26 Best AI Tools for Teachers in 2026 (Free Plans Verified)

Most lists of AI tools for teachers are either fifty links with no judgment or five tools the author happens to sell. This one is 26 tools sorted by the classroom job they do, from lesson planning and slides to live quizzes, grading and the platforms schools roll out to a whole staff, with each free plan written down the way the vendor states it.

A word on how much of this we have used ourselves. We build Sheelon, and we tested Edcafe AI directly for our quiz comparison. We tried Chalkie on its free plan on September 20, 2026: one lesson, one worksheet, one AI edit, one PDF export and its live follow-along mode. For the quiz section we also ran one prompt, once, through the generators of Kahoot, Edcafe AI, Sheelon, Wayground, Formative and QuestionWell on 19 and 20 September 2026 and had the output graded blind; the results are in that section. Everything else about those tools, and every other entry, is reported from the vendor’s own pages, checked on September 19, 2026. Where a vendor publishes no number, the entry says so instead of guessing.

Quick picks

• Best free all-rounder: MagicSchool AI, 80-plus teacher tools on a free plan whose caps are not published.
• Best for lesson planning: Brisk Teaching, 20-plus free tools that draft inside the Google Docs and Slides you already have open; Chalkie if what you need is a finished slide lesson from one topic.
• Best for slides: Canva for Education, free for verified K-12 teachers, with an AI quiz built from your slides; Gamma if you are not K-12.
• Best for live quizzes: Sheelon, and yes, that is us: 50 players, PIN join with no student account, AI generation and homework mode on the free plan. Wayground if you need 100 free participants.
• Best for grading: Gradescope, whose free Basic plan grades scanned paper work against rubrics; the AI grading is institutional.

All 26 tools compared

One row per tool, in the order the entries appear below, as each vendor published it on September 19, 2026. “Not published” means we found no number on a vendor page.

How we chose and what we tested

Three things had to be true for a tool to make the list. It does a real classroom job: drafting, presenting, assessing, differentiating, grading or managing, not AI for its own sake. A teacher can find out what it costs, from a free tier, a published price or at least a clear statement that it is a school purchase. And its claims are checkable: everything in these entries traces to the vendor’s public pages, and we flag where a vendor keeps its own limits vague.

We build Sheelon, and we tested Edcafe AI directly while researching our best AI quiz generator for teachers comparison. We also tried Chalkie on its free plan on September 20, 2026, and its entry says which parts we used. For the quiz generators we went one step further. On 19 and 20 September 2026 we gave six of them one fixed prompt: a 10-question multiple-choice quiz on photosynthesis for grade 7, four options, one correct answer, testing understanding rather than recall. Each tool got the prompt in whatever fields it exposed, with grade, type and count set to 7th grade, multiple choice and 10 where a control existed. We timed the seconds from clicking generate to a quiz that could be saved or hosted. Two graders, blind to each other, scored every key, reading level, cognitive level and distractor set, and an adjudicator ruled on every disputed key. A script counted where the correct answer sat and how often it was the longest option. Kahoot, Edcafe AI, Sheelon, Wayground and Formative ran on 19 and 20 September, and QuestionWell last, on 20 September, once a signed-in teacher account had passed its sign-in wall; one run each, generator step only. You can download the raw data (JSON): every question, both graders’ scores and the rulings.

Updated September 20, 2026. Prices and free tiers verified September 19, 2026 against each vendor’s own pages. Vendors change plans often, so confirm on the tool’s site before committing a class or a budget.

Lesson planning and content creation for the classroom

Prep is where teachers lose the most hours. Two assistants that draft from a prompt, a slide-lesson generator we tried on its free plan, an extension that works inside the files you already have, and a notebook that answers only from sources you give it.

1. MagicSchool AI

Best for: Everyday planning admin: lesson drafts, rubrics, report card comments, IEP paperwork.

MagicSchool AI is the broadest teacher assistant platform: more than 80 single-purpose tools for lesson plans, rubrics, quizzes and report comments, plus the Raina chatbot for everything else. Its homepage lists Google Classroom, Canvas, Schoology, Clever and ClassLink.

• 80-plus teacher tools on Free, including Raina
• Safeguards that flag PII leaks, bias and factual errors
• Plus adds unlimited generations and student tools

Limitation: the Free plan caps generations and output history without publishing the numbers, so you find the ceiling by hitting it; student tools and Google and Microsoft exports sit on Plus.

Free tier: $0, labeled forever free, 80+ teacher tools, unpublished generation limits. Paid: Plus at $8.33 per user per month billed annually, or $12.99 monthly; Enterprise custom. Verified September 19, 2026.

Students need an account: not stated; student tools are Plus features. Integrations: Google Classroom, Canvas and Schoology; SIS, LMS and SSO on Enterprise.

2. Eduaide.Ai

Best for: Guided lesson planning and resource creation instead of a blank prompt box.

Eduaide.Ai builds lesson plans, worksheets, graphic organizers, classroom games and assessments through guided workflows rather than free-form prompting. The pricing page calls Free “always free with generation limits” and gives Pro the same tools with unlimited AI generations.

• AI lesson and unit plan generators
• Graphic organizers and classroom games from a guided form
• School-wide subscriptions through a contact page

Limitation: the Free plan caps generation on the core workflows (lesson plans, worksheets, organizers, games, assessments) and limits the input you can give it for topics, standards and uploaded documents, without publishing the number, so you find the ceiling by hitting it.

Free tier: always free, with a generation limit on the core creation workflows and limited input context; the number is not published. Paid: Pro at $5.99 a month, with unlimited AI generations, document chat for revisions, image generation, YouTube transcripts as a source, 3x longer prompts, 5 standards and 3 uploaded documents; schools and districts request pricing. Verified September 19, 2026.

Students need an account: not stated. Integrations: none named on the pricing page.

3. Chalkie

Best for: A full, editable slide lesson from one topic in under a minute.

Chalkie turns a topic into a designed slide lesson through a three-step wizard: topic, refine, theme. When we tried it, a 10-slide grade 7 photosynthesis lesson arrived in 50 seconds with 9 images, three learning objectives, a key-words slide, one knowledge-check question and a recap. You edit in plain English (“make this slide simpler for a weaker reader” came back as 4 itemised, undoable edits in about 25 seconds) or type straight into any text box, and the same wizard builds worksheets from 10 templates and multi-lesson series.

• 10-slide lessons with images, objectives, key words and a knowledge check, from one topic
• Plain-English edits, itemised and undoable, on top of a real slide editor
• Worksheets from 10 templates, lesson series, and 32 themes with dyslexia, low-vision and ADHD filters

Limitation: the free plan is tight: 5 resources and 10 AI edits per 7 days, and every export carries a Chalkie badge until you pay for PRO. Standards alignment is PRO-only, and its 32-country list has no Israel and no Hebrew or Arabic curricula. A lesson holds one knowledge-check question, with no scoring and no student answers. The live Teach mode is follow-along only, and in our run the correct answer showed highlighted on the student device when the teacher reached the knowledge-check slide, which may have been the teacher’s own reveal carrying over; we could not tell. One generated diagram labelled a stack of thylakoids as “Chlorophyll”, a pigment rather than a structure; the slide text itself had no factual errors we could find.

Free tier: 5 resources and 10 AI edits per 7 days, lessons up to 12 slides, series up to 3 lessons. Paid: PRO at $6.65 a month billed yearly ($79.80) or $8.99 monthly, with 200 resources a month, standards alignment and badge removal; MAX at $12.99 a month billed yearly ($155.88). Tried on the free plan on September 20, 2026; caps and prices read from the app and its upgrade modal that day.

Exports to: Google Slides, PowerPoint and PDF on the free plan; the PDF we exported carried the Chalkie badge on every page, and badge removal is a PRO feature. Worksheets export to Google Docs, Word and PDF. Live interaction built in? Follow-along only: students see the current slide on their own device but cannot answer. Students need an account: no; the live mode uses a 6-digit code at chalkie.live. Output languages: 42, including Hebrew and Arabic; right-to-left rendering not verified. Privacy: the policy states FERPA school-official language and GDPR, does not mention COPPA, and tells teachers to avoid entering student PII.

4. Brisk Teaching

Best for: Feedback and content work inside the Google and Microsoft files you already have open.

Brisk Teaching is a Chrome and Edge extension, not a destination site. It drafts materials and writes feedback inside Google Docs, Slides, Forms and Classroom, Word, PowerPoint, Canvas, Schoology, YouTube, PDFs and web pages, in 50-plus languages.

• 20-plus tools on Free; paid tiers list 35-plus
• Glow and grow, next steps, rubric and batch feedback
• Brisk Boost student activities

Limitation: extension only, and the vendor’s pages disagree on free usage: the plans page says unlimited with a batch-feedback upload limit, the Educator Pro page says daily limits. Neither publishes numbers.

Free tier: Free (For Teachers) at $0, 20+ tools, the feedback toolkit, a batch-feedback upload limit. Paid: individual Educator Pro, price not published on a live page; Premium and Intelligence for schools and districts, custom. Verified September 19, 2026.

Students need an account: not stated; every activity is teacher created and controlled. Integrations: Google Docs, Slides, Forms, Classroom, Word, PowerPoint, Canvas, Blackboard, Schoology, YouTube.

5. NotebookLM (Gemini Notebook)

Best for: Grounded summaries, quizzes and audio recaps built from your own course materials.

NotebookLM, which Google’s help pages now call Gemini Notebook, answers only from the sources you upload, with citations back to them, and turns those sources into Audio and Video Overviews, quizzes, flashcards, mind maps and reports.

• Chat grounded in your uploaded sources, with citations
• Audio and Video Overviews, 3 a day each on free
• Quizzes, flashcards, reports and mind maps, 10 a day each

Limitation: the free caps are daily and firm, higher limits come only with Google AI Pro or Ultra, and there is no student join flow.

Free tier: 100 notebooks, 50 sources per notebook, 50 chats a day, 3 Audio and 3 Video Overviews a day, 10 Deep Research runs a month. Paid: higher limits through Google AI Pro and Ultra; no separate price published. Verified September 19, 2026.

Students need an account: not applicable; a teacher-side tool on a Google account. Integrations: none listed for Classroom, Slides or an LMS.

Presentations and slides for the classroom

Slides are where most lessons still live. An AI deck generator, a design platform that is free for K-12, a live writing platform and a PowerPoint add-in; each entry says what it exports to and whether students interact live.

6. Gamma

Best for: Fast AI-drafted lesson decks and one-page sites from a prompt or outline.

Gamma generates slide decks, documents and simple websites from a prompt or a pasted outline. It is a general productivity tool metered by credits: Free users get 400 at signup, and those do not refresh.

• Up to 10 slides per prompt on Free, 100 on Plus
• Plus removes the badge; Pro adds custom domains
• Referrals raise free credits to a 2,000 maximum

Limitation: free credits are one-time and the Gamma branding stays until you pay for Plus; every paid plan is priced per seat and billed annually.

Free tier: $0, 400 credits at signup that do not refresh, up to 10 slides per prompt, import from PDF and PPTX, Gamma branding. Paid: Plus at $9 per seat per month billed annually ($108 a year) with 1,000 monthly credits, up to 100 slides per prompt and no Gamma branding; Pro at $18 per seat per month billed annually ($216 a year); Ultra at $90 per seat per month billed annually. Verified September 19, 2026.

Exports to: PDF, PPTX, PNG and Google Slides, on the free plan. Live interaction built in? No. Students need an account: not applicable, an authoring tool. Integrations: none named on the pricing page, which does state SOC 2 Type II compliance.

7. Canva for Education

Best for: Student-facing design work: presentations, posters, videos and class projects.

Canva for Education is Canva’s design platform made free for verified K-12 teachers, their students and qualified districts. Canva’s education page calls it 100% free, with no paywalls or nasty surprises, and commits to keeping it that way for K-12 educators, their students and qualified school districts and institutions, with an AI quiz generator that turns lesson slides into quizzes.

• Free for verified K-12 educators, students and districts
• Students join through a teacher invitation
• AI quiz generator built from lesson slides

Limitation: K-12 only, meaning primary and secondary educators, their students and qualified districts and institutions, and access waits on verification: you sign up with an education email or upload proof of employment, and Canva verifies it within a few days.

Free tier: 100% free for verified K-12 educators, their students and qualified districts and institutions, with no paywalls. Paid: not applicable for eligible K-12 users. Verified September 19, 2026.

Exports to: not named on the education page. Live interaction built in? Not stated on the education page. Students need an account: yes, through a teacher invitation. Integrations: Google Classroom, Canvas, Schoology, Moodle, Blackboard, D2L and Microsoft Teams.

8. Curipod

Best for: Live, whole-class writing practice with AI feedback while the lesson is still running.

Curipod runs live lessons where students write in response to prompts on the board and get AI “Glow & Grow” feedback during the period, not days later. Lessons align to 55-plus curricula, and classroom reports capture every response and revision.

• Simultaneous student writing, entered by class code
• Real-time AI writing feedback, teacher controlled
• Test prep for reading and writing assessments

Limitation: no individual paid plan; both paid tiers are custom-priced school contracts, free ELA and Science practice is labeled limited usage, and responses stop at 1,000 characters.

Free tier: $0, weekly writing practice with instant feedback, unlimited student writers, 1,000-character responses. Paid: school and district plans, custom priced, with 5,000-character responses. Verified September 19, 2026.

Exports to: none published; lessons run inside Curipod. Live interaction built in? Yes, by class code. Students need an account: no; the homepage says students do not have accounts. Integrations: SSO via Google, Clever and ClassLink on district plans.

9. ClassPoint

Best for: PowerPoint on Windows with live questions and a leaderboard inside the deck.

ClassPoint, from Inknoe, is a PowerPoint add-in that turns slides into live quizzes, polls and gamified lessons. Its AI reads your slide content and writes questions from it, and students join at classpoint.app with a class code and a name.

• Eight question types, from word cloud to slide drawing
• AI question generator that reads the slides
• Stars, levels, badges and a leaderboard

Limitation: Windows only with desktop PowerPoint and, in the vendor’s words, not compatible with Macs; the free plan caps a class at 25 and gives 20 AI credits in total.

Free tier: Basic, free, class size 25, 5 question types, 20 AI quiz credits in total. Paid: Pro at USD 8 per month, USD 96 billed annually, for classes up to 200; Premium custom. Verified September 19, 2026.

Exports to: PPTX is the native file; Google Slides not published. Live interaction built in? Yes, with class-code join and a leaderboard. Students need an account: no. Integrations: PowerPoint on Windows; Classroom and LMS not published.

Quizzes and live games for the classroom

This is our home turf, so a disclosure first: we build Sheelon, the first tool below. The other five earn their places by doing jobs Sheelon does differently or not at all. Kahoot and Wayground get a longer look in our Kahoot alternatives comparison, and if a quiz tool is all you need, the best free quiz platform for teachers post is the shorter read.

Same prompt, six generators: what came back

One prompt, one run per tool, on 19 and 20 September 2026: a 10-question multiple-choice quiz on photosynthesis for grade 7, testing understanding rather than recall. Keys were judged by two blind graders with an adjudicator on disputes; positions and lengths were counted by a script. Generators are not deterministic, so a second run would give a different quiz and possibly a different tally. Sheelon is ours and was graded the same way. The full method is in how we chose and what we tested, and the questions, scores and rulings are in the raw data (JSON).

What the run showed, with the example behind each point:

• The correct answer clusters in one slot. Formative put it in A on six of ten questions, Kahoot in B on six of nine, Edcafe in B on five of ten and Wayground in D on five of ten. A student who notices the pattern can guess without reading. Sheelon’s spread was 3/2/2/3 across A to D, and QuestionWell’s 3/3/1/3 was balanced too.
• Formative keyed two of ten questions wrong. “What do plants use from sunlight to make food?” was keyed to Chlorophyll, which the plant makes itself, and “Which of these is a raw material in photosynthesis?” was keyed to Sunlight with neither carbon dioxide nor water on the list. QuestionWell keyed two wrong as well. It keyed carbon dioxide as the thing a plant photosynthesizing without water would not need, when carbon dioxide is an input the plant still needs and water, the only real answer, was not offered; and its sealed-box question asked which gas would be the main one after a day, then offered only “more” and “less” changes, never a gas. Kahoot, Edcafe and Wayground had clean keys; Sheelon had one ambiguous item, a chlorophyll colour question whose distractor B restates the key in looser words.
• Weak distractors were the shared weakness. Every tool scored between 2.5 and 3.3 out of 5 on distractor quality. Kahoot offered “Shelter and fur”, “Heat and sound” and “Water and bones” as wrong answers to what photosynthesis gives animals; Wayground offered “Milk from another plant” as a plant input; Sheelon, highest at 3.3, still produced “They capture underground light rays” as a root-hair option. Wayground also had the longest option as the key on five of ten, its tree-removal question pairing a hedged 17-word key against “all”, “immediately” and “ever”.
• Reading level drifted in both directions. Edcafe asked about mesophyll cells, xylem vessels and “the light reactions”, which are grade 9 or 10 material. Sheelon’s food-web question reads like a high school text (“foundational base of almost all terrestrial and aquatic food webs”) and several of its stems use stiff phrasing such as “primary chemical end products”. One grader rated six of Formative’s ten items as too easy for grade 7. QuestionWell’s ten stems fit grade 7 for both graders, though half the set was recall.
• Formatting costs time too. Edcafe printed chemical formulas as raw LaTeX in five of ten questions, so a student would see “$CO_2$, $H_2O$, and sunlight” unless the teacher cleans it up. Kahoot’s answers came out as one to four words, and its tenth card was a confidence poll with no correct answer that the free plan could not add, so the saved kahoot had nine questions. QuestionWell, given only a topic, first wrote itself a “reading” that was literally a ten-question quiz with an answer key, then generated the real questions from that reading, and took 50 seconds to do it, the slowest of the six.

10. Sheelon

Best for: Live quiz games and self-paced homework with AI drafting on the free plan.

Sheelon is our own product; we build it, so weigh this entry accordingly. Students join a live game with a PIN in any browser, no accounts, and the same quiz runs as homework on every plan. The AI quiz maker builds a quiz from a topic on every plan and from an uploaded PDF, Word file or slide deck on Pro.

• Live games by PIN, up to 50 players on Free
• AI quiz generation from a topic; from a document on Pro
• Homework free on every plan, post-game report on screen

Limitation: free AI is 5 quizzes for life, Free has 3 of the 10 question types, document upload is Pro, result exports are Pro, Google Classroom import is Ultimate, and there is no Slides or PowerPoint add-in. In the same-prompt test Sheelon keyed one of ten questions ambiguously (the chlorophyll colour question has a distractor that restates the key), wrote several stems in a high school register, spent a question on van Helmont’s 1643 experiment, which is history trivia the brief did not ask for, and at 25.5 seconds was slower than every generator except QuestionWell. Its topic field caps at 200 characters, so the shared prompt had to be trimmed. The run used the owner’s Ultimate account, so the free-plan caps above were not exercised.

Free tier: $0 forever, 50 players per game, 3 question types (multiple choice, true/false, type answer), 5 lifetime AI generations, unlimited hand-written quizzes, homework mode. Paid: Pro at $3.99 per month or $39 per year with 150 players, all 10 types and unlimited AI; Ultimate at $9.99 per month or $99 per year with 500 players. No free trial. Verified September 19, 2026.

Students need an account: no; they type a PIN in the browser. Integrations: Google Classroom import and LMS integration on Ultimate; LTI on the School plan.

11. Kahoot!

Best for: The best-known PIN game, if 40 players on free and AI from a topic or a PDF are enough.

Kahoot! is the live quiz most students already recognise: a PIN on the board, phones out, music on. The free Kahoot! Go plan covers live games and assigned kahoots, and its AI Assistant generates from a topic or a PDF. The URL, Wikipedia and slides sources, Add all and some of the card types it generates (the poll, for one) carried a premium mark on the free plan when we ran it.

• Live games by PIN plus assigned kahoots on free
• AI Assistant from a topic or PDF on free; URL, Wikipedia and slides sources on Kahoot!+
• Slides and PowerPoint import on Silver and up

Limitation: the free plan stops at 40 players with quiz and true/false questions only, and every paid plan is billed a full year upfront. In the same-prompt test the AI Assistant ran three times on a free Go account from the Topic source, but the confidence poll it generated as the tenth card carried a premium mark and could not be added, so the saved kahoot had nine questions; Add all was premium too. All nine quiz keys were correct, six of them in slot B.

Free tier: Kahoot! Go, free, 40 participants per live game, quiz and true/false types, assigned kahoots, basic reports. Paid: Bronze at $3 per month, $36 billed annually, for 50 players; Silver $84 a year for 100; Gold $144 for 200; Kahoot! One $228 for 800. Verified September 19, 2026.

Students need an account: not stated on the pages we read; a game is joined with a unique PIN. Integrations: Google Classroom assignments and Zoom on all plans; Slides and PowerPoint import on Silver and up; LTI 1.3 for Moodle, Canvas, Blackboard, Brightspace and Schoology on EDU Pro.

12. Wayground (formerly Quizizz)

Best for: A free plan with 100 participants and AI quizzes, if 5 question types are enough.

Wayground is the platform that used to be Quizizz: live and self-paced quizzes, lessons, flashcards and interactive video in one library, with AI generation on every plan. Wayground AI generates, imports and adapts content and writes answer explanations for students.

• Up to 100 participants on the free Basic plan
• AI generation and adaptation with answer explanations
• Read aloud, extra time and multiple attempts on free

Limitation: free accounts get 10 AI credits a month, 5 question types, a 20-activity storage cap and no premium question types, and the Individual plan is billed a year upfront. In the same-prompt test all ten keys were correct, but the correct option was the longest one on five of ten questions (48 characters on average against 38.5 for the wrong ones), and the correct answer sat in slot D on five of ten. No credit counter appeared anywhere during the run.

Free tier: Basic, free with no credit card, 100 participants, 5 question types, 10 AI credits a month, 20 activities. Paid: Individual at $18 per month, billed annually at $216, with 1,000 participants and a 7-day trial; school plans through sales. Verified September 19, 2026.

Students need an account: no; students join with the teacher’s code, and accounts only save progress. Integrations: Google Classroom (limited on Basic, grade passback on school plans); Canvas, Schoology, Clever, ClassLink and Teams on school plans.

13. QuestionWell

Best for: Generating aligned question banks that you play or assign somewhere else.

QuestionWell does one job and feeds everyone else: standards-aligned questions from a topic or a reading, in multiple choice, fill in the blank, short answer, true/false and multi-select, exported to the tool you teach with, from Kahoot and Blooket to Canvas and Google Forms. It also has its own self-paced assignment mode with a student code and a live dashboard, but no synchronous game.

• Unlimited multiple choice and discussion questions on Free
• Standards search so questions align to what you teach
• 21 export targets in the app, from Kahoot, Quizizz (now Wayground) and Blooket to Google Forms, Canvas and Moodle

Limitation: on Free, almost everything except generating questions is capped at 5 a month: exports, assignment codes, premium question types, AI edits, plus 2 classes and 3 months of storage; the generator sits behind a sign-in; and no FERPA or COPPA statement appears on the pages we read. In the same-prompt test it delivered ten questions in 50 seconds, the slowest of the six, and keyed two of them wrong: carbon dioxide as what a plant photosynthesizing without water would not need, and a sealed-box question that asked for a gas but offered only more-or-less changes. Its correct answers were spread 3/3/1/3 across A to D, and every stem fit grade 7 for both graders.

Free tier: $0, unlimited multiple choice and discussion questions, exports and most features 5 a month, 2 classes. Paid: Premium at $5.83 per month billed annually ($70 a year); School and District at $100 per seat per year for 5 to 50 seats. Verified September 19, 2026.

Students need an account: not verified; the Interactive Quiz option generates an assignment code for students, 5 codes a month on Free, and we did not generate one. Integrations: 21 export targets seen in the app, including Google Slides, Google Forms, Google Docs, Microsoft Forms, Word, Kahoot, Quizizz (now Wayground), Blooket, Gimkit, Quizlet, Canvas, Moodle, Schoology, Blackboard and Brightspace, 5 exports a month on Free; no Google Classroom export.

14. Formative

Best for: Watching student responses arrive live, question by question, during a lesson.

Formative is built around a live response view: deliver an activity and watch every student’s answers populate in real time, with auto-grading and rubrics. Its AI assistant Luna generates standards-aligned content from prompts, PDFs or documents and proposes Next Steps follow-up activities.

• Real-time response data with auto-grading and rubrics
• Luna AI generation from prompts and documents
• Roster sync via Google Classroom, Clever and ClassLink

Limitation: the Free plan appears only on the homepage, not the pricing page, with unpublished limits, and the Classroom plan is capped at fewer than 100 students and billed annually only. In the same-prompt test Luna was the fastest generator at 9.1 seconds but keyed two of ten questions wrong (Chlorophyll as what plants use from sunlight; Sunlight as a raw material with neither carbon dioxide nor water offered), put the correct answer in slot A on six of ten, and returned eight recall items out of ten. That run used the Paid Teacher trial new accounts get, not the free plan.

Free tier: assignment creation, basic question types and student responses; limits not published. Paid: Classroom at $20.75 per month billed annually ($249 a year) per teacher; Small School at $3,125 a year for up to 250 students; districts custom. Verified September 19, 2026.

Students need an account: not stated explicitly; students join by code or through rostering. Integrations: Google Classroom, Clever and ClassLink rostering; Google Slides integration.

15. Edcafe AI

Best for: Self-paced AI-drafted activities with a generous free drafting allowance, and no live mode.

Edcafe AI generates quizzes, flashcards, custom chatbots, slide decks and reading activities from a topic, a text, a web page or a YouTube video, hands them to students and tracks progress. Its 100 free AI generations a month is the most generous metered allowance in this section, ahead of our own; only QuestionWell’s unlimited multiple choice generation is looser.

• 100 monthly AI generations on Free, 1,000 on Pro
• Assignment graders with progress dashboards
• Chatbot conversations monitored for signs of distress

Limitation: from our hands-on testing, there is no live game mode, generating from your own files needs the paid plan, the free plan stops collecting after 40 responses per activity, and right-to-left languages such as Hebrew are not usable yet. In the same-prompt test all ten keys were correct, but five of ten questions showed chemical formulas as raw LaTeX in the options (“$CO_2$, $H_2O$, and sunlight”), two questions reached for grade 9 or 10 terms (mesophyll, xylem, “the light reactions”), and the correct answer sat in slot B on five of ten.

Free tier: $0, 100 AI generations a month, 3 chatbots, 3 graders, 40 participants per activity. Paid: Pro at $7.99 per month billed annually with 200 participants; Premium at $14.99 per month billed annually with LMS integration; no monthly billing. Verified September 19, 2026.

Students need an account: not stated; in our testing activities go out by QR code or link. Integrations: Canvas, Moodle and Blackboard on Premium; no Google Classroom, Slides or PowerPoint.

General assistants and tutoring

The two general assistants most teachers already have open in a tab, each with an education edition, and a tutor from a nonprofit that gives teachers its prep tools for free.

16. ChatGPT

Best for: One general assistant for planning, rewriting and differentiating materials.

ChatGPT is OpenAI’s general-purpose assistant and, for many teachers, the first AI tool they reach for: paste a text and ask for three reading levels or five exit-ticket questions. OpenAI also runs a separate ChatGPT for Teachers workspace, free for verified U.S. K-12 educators through June 2028: a secure workspace where content is not used to train models by default, built to help schools meet FERPA requirements.

• Free plan at $0 with unlimited text chats
• Business plan: no training on your data by default
• ChatGPT for Teachers: unlimited messages, search, file uploads and image generation, with Canva, Google Drive and Microsoft 365 connections

Limitation: nothing is classroom-specific on the consumer plan, no rosters, no student join, no gradebook, and the Teachers workspace is for verified U.S. K-12 educators only, with a free period that runs through June 2028.

Free tier: $0 per month, unlimited text chats with limited uploads, image generation, voice and deep research; ChatGPT for Teachers free for verified U.S. K-12 educators through June 2028, with unlimited messages, search, file uploads and image generation. Paid: Go at $8 per month, Plus at $20, Pro from $100; Business, Enterprise and Edu plans for organizations. Verified September 19, 2026.

Students need an account: consumer ChatGPT is a personal account; ChatGPT for Teachers is a workspace for educators. Integrations: Canva, Google Drive and Microsoft 365 connections in ChatGPT for Teachers, with admin controls and SAML SSO for districts.

17. Gemini

Best for: Schools on Google Workspace for Education that want quiz, rubric and lesson generation inside Classroom.

Gemini is Google’s assistant, free in the consumer app and included at no cost in every Google Workspace for Education edition. Gemini in Classroom puts the teacher tools where teachers already work: lesson outlines, quizzes, rubrics, re-leveled text, vocabulary lists and translation, with an admin console deciding who has access.

• Gemini in Classroom with every Workspace for Education edition
• Extra guardrails for students under 18
• Gems, Canvas, Deep Research and Gemini Live in the app

Limitation: the teacher tools need a Workspace for Education account and an admin who has switched Gemini on, and there is no live PIN-join quiz game.

Free tier: consumer app free plan; Gemini for Education included free of charge in all Workspace for Education editions. Paid: Google AI Plus at $4.99 per month for consumers; Google AI Pro for Education at $20 per user per month on a one-year commitment, or $24 monthly. Verified September 19, 2026.

Students need an account: yes for school use, a Workspace for Education licence with Gemini enabled by an admin. Integrations: Google Classroom on every education edition; Gmail, Docs, Meet and Forms through the AI Pro for Education add-on.

18. Khanmigo

Best for: Standards-aligned prep materials at no cost, especially if your classes already use Khan Academy.

Khanmigo is Khan Academy’s AI assistant. Its teacher toolkit, free in more than 180 countries and territories with Microsoft covering the Azure OpenAI costs, produces lesson plans, quiz questions, rubrics, exit tickets and student groupings; for learners it is a paid tutor.

• Free teacher tools: lesson plans, quiz questions, rubrics
• Writing Coach for student essays on district plans
• Google Classroom roster import from the teacher dashboard

Limitation: teachers cannot grant students Khanmigo access; student use comes only through a school or district implementation or a paid U.S. learner plan managed by a parent.

Free tier: teacher tools free with a sign-up and no published caps. Paid: learners and parents at $4 per month or $44 per year with a U.S. billing address; districts at $10 per student per year on Enterprise Starter. Verified September 19, 2026.

Students need an account: yes, Khan Academy accounts through a school, a district or a parent. Integrations: Google Classroom roster import and sync; Clever and ClassLink on district plans.

Differentiation and accessibility

Three tools for the gap between the text you have and the readers in the room: one rewrites materials to level, two make any text audible and readable.

19. Diffit

Best for: Leveled versions of the same text so the whole class works with the same ideas.

Diffit takes a topic, a text or a source you already use and produces print-ready reading materials at different reading levels and in different languages, with scaffolds and activities attached. It states that it collects no student data.

• Same content at several reading levels and languages
• Graphic organizers such as CER and Cornell Notes on paid
• Standards, MTSS tier and DOK alignment on paid

Limitation: the free Basic plan is limited to PDF, print or share output and shows only resources made in the last 90 days; editable exports and standards alignment are paid.

Free tier: Basic, free, full generation with PDF and print output and 90-day access. Paid: $14.99 per month or $149.99 per year for an individual teacher; Diffit for Schools is a flat annual rate tiered by enrolment, quoted. Verified September 19, 2026.

Students need an account: not applicable; a teacher-only tool. Integrations: exports to Google Docs, Slides, Forms and Classroom and to Microsoft 365 on paid plans.

20. Microsoft Immersive Reader

Best for: Read-aloud and reading supports already installed in a school running Microsoft 365.

Immersive Reader is not an app you buy but a free reading-support layer built into Word, OneNote, Outlook, Excel, Teams, Forms, Edge, Reading Progress, Reading Coach and Minecraft Education Edition. It reads text aloud with each word highlighted, shows one, three or five lines at a time, spaces text and splits syllables.

• Read Aloud with word-by-word highlighting
• Line Focus, Text Spacing, Syllables and Page Color
• Picture Dictionary and Translate in Word for the web

Limitation: it exists only inside host products, and some features are web-only in Word, so it is not an option for a classroom running entirely on other platforms.

Free tier: free inside Microsoft 365 apps. Paid: none; a built-in feature with no separate price. Verified September 19, 2026.

Students need an account: not stated; it runs inside whichever host app the student already uses. Integrations: Microsoft 365 and third-party apps; no Google Classroom or LMS integration published.

21. NaturalReader

Best for: Turning course readings into audio students can listen to anywhere.

NaturalReader reads documents, web pages, books and scanned pages aloud in AI voices on the web, in a mobile app and in a Chrome extension, with hundreds of voices across 90-plus languages.

• Reads PDFs, documents, web pages and scans aloud
• Hundreds of AI voices across 90-plus languages
• EDU licence with dyslexia-friendly font and captions

Limitation: the free plan caps the better voices by characters per day and cannot convert to MP3, and the pricing page URL still returns an error, so prices live in the help center.

Free tier: free forever, unlimited Free voices, 20,000 characters a day with Lite voices, 4,000 a day shared across Plus and Cloned voices, no MP3. Paid: Lite at $13.90 per month or $79 a year, Plus $20.90 or $119, Pro $25.90 or $159; EDU has a free group licence, a 30-day trial and a site licence from USD 3,300 for 2,000 users. Verified September 19, 2026.

Students need an account: yes for EDU, where every student receives one. Integrations: none published; Chrome extension plus web, desktop, mobile and Chromebook apps.

Feedback and grading

Two graders and one tool from the student side of the desk. Fair warning: this category is where public pricing goes to hide.

22. Gradescope

Best for: Grading stacks of paper exams and problem sets faster, with consistent rubrics.

Gradescope, part of Turnitin, digitizes grading of scanned paper work, online submissions and code against dynamic rubrics, question by question, with regrade requests and per-question statistics. Its free Basic tier continues after the institutional trial ends.

• Dynamic rubrics and question-by-question grading on Basic
• AI-Powered Grading and Roster Matching on Institutional
• Programming and bubble sheet assignments on Institutional

Limitation: AI grading, LMS integration, bubble sheets and programming assignments are Institutional only, and Institutional has no published price.

Free tier: Basic, free after the institutional trial, with rubrics, PDF assignments, statistics, regrade requests and data export; no AI. Paid: Institutional, contact the vendor; no public pricing. Verified September 19, 2026.

Students need an account: not stated; Basic lists student-uploaded PDFs and a student app. Integrations: LMS integration and SSO on Institutional only; Google Classroom not mentioned.

23. FeedbackFruits

Best for: Structured peer review and feedback workflows inside a university LMS.

FeedbackFruits is a suite of LMS-integrated learning activities for universities: peer review, group member evaluation, interactive video and documents, oral assessment and team-based learning, with an AI layer called Acai. It runs inside the LMS with live sync of grades, groups and deadlines and reports 200-plus institutions.

• Peer Review, Group Member Evaluation and Self-Assessment
• Interactive Video and Interactive Document
• Acai AI for feedback and coaching inside the LMS

Limitation: no free tier, no public pricing and no self-serve signup; access comes through an institutional deal and a demo, and the free Educators Initiative closed in January 2024.

Free tier: none. Paid: packages by number of learning activities, through a demo; no published price. Verified September 19, 2026.

Students need an account: no separate login; it is integrated in the LMS. Integrations: LMS only, with a dedicated Canvas page and a Moodle setup guide; no Google Classroom.

24. QANDA

Best for: Understanding the AI math helper your students are probably already using.

QANDA is here for the student side of the desk: a mobile study app from Mathpresso where a student photographs a problem and gets AI solutions and tutoring within seconds, and the company reports 8 million monthly users. For teachers it is less a tool to adopt than a reality to design homework around.

• Photo problem search with AI solutions in seconds
• QANDA Tutor, tablet-based 1:1 tutoring with screen sharing
• Mobile app plus a web site

Limitation: the vendor site publishes no pricing, plan or free-tier details, a Premium plan exists with no published price, and there is nothing for a teacher to adopt.

Free tier: not published; the app is presented as a download with no cost stated. Paid: a Premium plan exists; no published price. Verified September 19, 2026.

Students need an account: not stated; a student-facing app. Integrations: none published.

Classroom management

Two platforms schools adopt wholesale rather than tools a teacher picks up on a free afternoon.

25. SchoolAI

Best for: Giving students a monitored AI assistant inside teacher-set guardrails.

SchoolAI gives K-12 students an AI assistant called Dot inside Spaces, experiences the teacher designs and controls, while a Mission Control dashboard shows who is engaged, who is stuck and what to do next. Its compliance page lists SOC 2 Type 2, FERPA, COPPA and 1EdTech TrustEd Apps.

• Spaces with teacher-set guardrails and a live dashboard
• PowerUps, focused AI apps for students
• Rostering through 30-plus SIS partners on paid plans

Limitation: the entry plan is literally named Free Trial and allows 5 Space launches a year, so real use of the headline feature needs Pro or Scale, neither of which has a published price.

Free tier: a plan named Free Trial with 5 Space launches a year and a standard data privacy agreement. Paid: Pro and Scale, contact sales; no published price. Verified September 19, 2026.

Students need an account: no; students joining with a Space Code type their name. Integrations: Canvas, Google Classroom and Schoology; SSO via Clever, ClassLink, Microsoft and Google.

26. Kiddom

Best for: Schools adopting a full digital curriculum with AI-assisted grading built in.

Kiddom is a K-12 curriculum platform rather than a single-purpose tool. It delivers open curricula such as Illustrative Mathematics, EL Education and OpenSciEd digitally, with AI grading of open-ended responses, AI feedback, and Atlas, which analyzes assessments, builds student groups automatically and prepares warm-ups for them.

• Illustrative Mathematics, EL Education and OpenSciEd, delivered digitally
• AI grading and feedback on open-ended responses
• Atlas groups students from assessment data

Limitation: a school or district purchase; teacher access is free only alongside a school’s student licences, and no individual teacher signup is published.

Free tier: none standalone; teachers get access free with their school’s student licences. Paid: curriculum licences on a national price list, for example Kiddom IM v.360 Math at $27 per student per year; platform bundles and district pricing by quote. Verified September 19, 2026.

Students need an account: yes, rostered by the school. Integrations: rostering listed as a support topic; Google Classroom, Clever and ClassLink not named on the pages we read.

AI tools students can use

Most of this guide is for the teacher’s side of the desk. Three of the tools also work in a student’s hands. Khanmigo has a learner tutor, but a student only gets it through a school or district plan or a parent-managed plan. NotebookLM lets an older student study from their own notes with every answer cited back to the source. And on Sheelon a student needs no account at all: they type a PIN in the browser to join a live game or a homework set, and the free community quiz library has ready-made quizzes a class can practise with.

What “free” actually means for teachers

Five different things hide behind the word free on vendor pages, and they are worth telling apart before you build a lesson on one.

• A free plan you keep forever with published caps: Sheelon (50 players, 5 lifetime AI quizzes), Wayground (100 participants, 10 AI credits a month), ClassPoint (25 students, 20 AI credits in total), Edcafe AI (100 generations a month), NotebookLM (3 Audio Overviews a day), QuestionWell (5 exports a month), Chalkie (5 resources and 10 AI edits per 7 days), Diffit (90 days of access) and Kahoot (40 players, AI from a topic or PDF). MagicSchool and Brisk have free plans too, but neither publishes its numbers.
• Free outright: Immersive Reader inside Microsoft 365, and Khanmigo’s teacher toolkit with a sign-up in 180-plus countries.
• Free for verified educators: Canva for Education for verified K-12 staff, and Gemini for Education for anyone on a Workspace for Education edition.
• A trial: SchoolAI’s entry plan is named Free Trial and stops at 5 Space launches a year. Sheelon has no trial at all; the free plan is the free plan.
• A school account: FeedbackFruits, Kiddom and Gradescope’s AI features are bought by an institution, not signed up for tonight.

If free is the whole question, we keep a separate list of free AI tools for teachers, and quiz-only readers should go straight to the best free quiz platform for teachers or the broader look at free quiz tools for the classroom.

Where AI output falls short

Every tool on this page can produce something you would not want a student to see. Rather than describe the failures in general, here is what one run of the same-prompt test put in front of us, from six generators asked for the same grade 7 photosynthesis quiz.

Wrong keys, in a confident tone. Formative keyed “What do plants use from sunlight to make food?” to Chlorophyll, which the plant makes itself; none of its four options was something a plant takes from sunlight. It keyed “Which of these is a raw material in photosynthesis?” to Sunlight, with neither carbon dioxide nor water offered. Both questions read like the correct ones next to them. QuestionWell did the same twice: it keyed carbon dioxide as the thing a plant photosynthesizing without water would not need, when the plant still needs it and water, the only honest answer, was not an option; and its sealed-box question asked which gas would be the main one after a day, then offered only “more carbon dioxide”, “less carbon dioxide”, “more nitrogen gas” and “less oxygen gas”, each a change in amount rather than an answer to “which gas”, so no option answers the stem. Sheelon produced one ambiguous key of its own: on the chlorophyll colour question, distractor B is a looser restatement of the keyed answer. Across the six tools the keys came out 10/10, 10/10, 9/10, 9/10, 8/10 and 7/10.

The answer sits in the same slot. Formative put the correct option in A on six of ten questions. Kahoot put it in B on six of nine, Edcafe in B on five of ten, Wayground in D on five of ten. Sheelon’s generator shuffles options in code after generation and runs a verifier that rejects a set where position or length gives the answer away; in this run its spread was 3/2/2/3 across A to D, and its correct option was the longest on one of ten. QuestionWell’s 3/3/1/3 was balanced without any such step.

The longest option is the answer. Wayground had the correct option as the longest on five of ten questions, with correct answers averaging 48 characters against 38.5 for the wrong ones; its tree-removal question pairs a hedged 17-word key with three short absolutes. Edcafe had it on four of ten, QuestionWell on three of ten with one tie, Kahoot on two of nine, Formative on two of ten. Several tools also set a hedged key (“could increase”, “may reduce”) against absolute distractors, which test-wise students spot.

Things that are not questions, and text that is not text. Kahoot’s tenth card was a confidence poll with four feelings and no correct answer, counted toward the ten you asked for and not addable on the free plan. Edcafe printed chemical formulas as raw LaTeX in five of ten questions, so students would see “$CO_2$, $H_2O$, and sunlight” unless the teacher cleans it up. Formative asked for the outputs of photosynthesis three separate times in one quiz, and returned eight recall items out of ten after a prompt that asked for understanding.

Five minutes on a ten-question quiz covers all of it. Before class, whichever tool you use:

1. Read every key. Not the questions, the keyed answers. Two of Formative’s ten and two of QuestionWell’s were wrong, and all four looked fine at a glance.
2. Check the position spread. Count how many correct answers sit in each slot. Six in one slot is a pattern students will find; move some.
3. Check option lengths. If the longest option is the key on more than three questions, trim it or pad a distractor.
4. Cut recall duplicates. If two questions ask the same fact in different words, keep one and rewrite the other to ask why or what would happen if.
5. Fix the reading level. Replace terms your class has not met (mesophyll, xylem, “reactants”) and shorten any stem that reads like a textbook two grades up.

How to build your stack

Nobody needs twenty-six tools. A workable classroom stack is one tool per job, and half the jobs may already be covered by what your school pays for.

• Start with what is already free for you. Immersive Reader if your school runs Microsoft 365, Gemini for Education if it runs Google Workspace, Canva for Education if you teach K-12.
• Pick one planning assistant, not three. MagicSchool for breadth, Brisk if your working life is inside Google Docs, NotebookLM when the output must stay grounded in your own sources, Chalkie when the output has to be a slide deck by tomorrow.
• Match the quiz tool to the mode you teach in. Live class play with no student accounts: Sheelon, and yes, that is us. Question banks to export elsewhere: QuestionWell. Self-paced with no live element: Edcafe AI.
• Differentiate the text, not just the task. Diffit for leveled versions of the same material, NaturalReader when audio is the accommodation that actually gets used.
• Grading and school-wide tools depend on who pays. Gradescope Basic is the only self-serve free option here; FeedbackFruits, SchoolAI and Kiddom are conversations for whoever holds the budget.

Frequently asked questions

What is the best AI tool for teachers in 2026?

There is no single winner, because the tools do different jobs. MagicSchool AI gives the widest free planning toolkit, Canva for Education is free for verified K-12 teachers who need slides, and for live classroom quizzes Sheelon (our product) gives 50 players, PIN join and AI generation on the free plan. Pick one tool per job rather than one tool for everything.

Is there a free AI tool for teachers?

Yes, most of the 26 tools here have a free plan, and a few are free outright. Microsoft Immersive Reader ships inside Microsoft 365, Khanmigo's teacher tools are free in 180-plus countries, Gemini for Education comes with every Google Workspace for Education edition, and Canva for Education is free for verified K-12 staff. The rest have free plans with real ceilings, listed tool by tool above.

Which AI teacher tools are actually free?

Free outright: Immersive Reader inside Microsoft 365, and Khanmigo's teacher toolkit with a sign-up in 180-plus countries. Free with published caps: Sheelon (50 players, 3 question types, 5 lifetime AI quizzes), Wayground (100 participants, 10 AI credits a month), ClassPoint (25 students, 20 AI credits in total), Edcafe AI (100 generations a month), NotebookLM (3 Audio Overviews a day), QuestionWell (5 exports a month) and Chalkie (5 resources and 10 AI edits per 7 days). Free in name only: SchoolAI, whose entry plan is a trial with 5 Space launches a year, and FeedbackFruits, which has no free tier.

Are AI tools safe for student data (FERPA and COPPA)?

Only if the vendor says so in writing, and only for the plan you are on. Tools publishing FERPA and COPPA statements on their own pages include MagicSchool, Curipod, Brisk, Wayground, ClassPoint, Formative, Edcafe, Diffit, NaturalReader, SchoolAI, Kiddom, Kahoot and Sheelon; Chalkie's policy has FERPA and GDPR language but no COPPA mention; several others publish nothing. Before students touch a tool, check whether student data trains the model and whether the free plan carries the same data agreement as the paid one.

Do students need accounts to use these tools?

It depends on the tool, and it decides how much setup a classroom needs. Sheelon, Wayground, Curipod, ClassPoint and SchoolAI let students join with a PIN or code and a name, no account. Kahoot games are joined with a PIN, but the pages we read do not say whether an account is needed. Chalkie's live follow-along mode takes a 6-digit code and no login. Canva for Education, Khanmigo, NaturalReader EDU and Kiddom put students on rostered accounts, and teacher-only tools such as Diffit and NotebookLM never involve students at all. QuestionWell has its own self-paced assignment mode that hands students a code; we did not generate one, so whether an account is needed there is unverified.

Can AI make a quiz from my lesson?

Yes, and on several tools it is free. Sheelon turns a topic into a playable quiz, 5 generations on the free plan; Pro makes generation unlimited and adds building a quiz from an uploaded PDF, Word file or slide deck. ClassPoint reads your PowerPoint slides and writes questions from them; QuestionWell writes standards-aligned questions you export to the platform you already use. When we ran one photosynthesis prompt through six generators in September 2026, the answer keys came out 10/10, 10/10, 9/10, 9/10, 8/10 and 7/10 correct (Edcafe AI, Wayground, Kahoot, Sheelon, QuestionWell, Formative), so every key still needs reading before you play it, for the reasons in the section on where AI output falls short.

Which AI tool is best for classroom presentations?

If you are a verified K-12 teacher, Canva for Education, because it is free and its AI can turn lesson slides into a quiz. If you present from PowerPoint on Windows and want live questions inside the deck, ClassPoint. If you need a deck drafted from an outline in minutes, Gamma, with the caveat that free credits are a one-time 400 and the Gamma badge stays until you pay.

Which AI tools are best for students?

Khanmigo, for its learner tutor, though students only get it through a school or district plan or a parent-managed plan. NotebookLM, for study from their own notes with citations back to the source. And any live quiz tool that lets them join without an account: on Sheelon they type a PIN in the browser and play.

How do teachers get started with AI in the classroom?

Start with one job that costs you time every week, such as writing a quiz or leveling a text, and pick one free tool for it from this guide. Use it for two weeks with your own materials, read every output before a student sees it, and keep it only if it saves time. Check your school's data policy before any student-facing tool.

Can AI replace teachers?

No. Every tool here drafts, grades, levels or summarises, and every one of them produces wrong facts, recall-only questions and odd phrasing often enough that a teacher has to read the output. What AI changes is where the hours go: less time writing the third version of a worksheet, more time on which students got question four wrong and why.
