1. ChatGPT for Teachers
Best for: teachers who want one broad workspace for planning, research, files, images, data analysis and reusable custom workflows.
OpenAI currently makes ChatGPT for Teachers free through June 2028 for verified U.S. K–12 educators. The product includes education-focused protections plus tools such as file uploads, web/deep research, image generation, data analysis, memory, custom GPTs and shared workspaces.
School and district administrators can also use controls such as SSO, RBAC, domain claiming and analytics.
Watch for: this offer is U.S. K–12 specific and is not currently a student-account product.

2. Claude for Teachers
Best for: teachers who want educator-specific lesson-planning and differentiation skills plus standards/curriculum context.
Anthropic says verified U.S. K–12 educators who sign up by June 30, 2027 receive a full year of free Claude for Teachers access. The plan includes Pro-level features, teaching skills, the Learning Commons connector and education-specific data terms.
Anthropic also now offers a separate free Enterprise setup for qualifying U.S. K–12 schools and districts.
Watch for: individual Claude for Teachers accounts do not expose every Team/Enterprise administration feature.

3. MagicSchool
Best for: teachers who prefer a large menu of task-specific education tools rather than starting every workflow with a blank chatbot.
MagicSchool's current Free plan is $0 and described as “Forever Free” for individual teachers. The provider lists 80+ teacher tools, its Raina chatbot, quizzes, class writing feedback and basic support/professional development.
Free-plan limitation: MagicSchool lists unlimited generations as a Plus feature, so teachers should expect more constraints on the free tier.
Check MagicSchool's current plans.
4. Brisk Teaching
Best for: teachers who want AI to work inside the web pages, documents, slides and resources they already use.
Brisk's teacher plan is currently $0. Its Free Forever plan includes 20+ AI-powered tools such as quiz, lesson-plan, rubric, podcast and presentation creation.
Free-plan limitation: school and district features are separate premium offerings. New sign-ups may also see a temporary premium trial before reverting to the free plan.
5. Diffit
Best for: teachers who need differentiated reading and classroom resources.
Diffit maintains a Basic free option that can create classroom-ready content, download/print materials and allow editing or adaptation.
Free-plan limitation: Diffit's official pricing page describes the free plan as having limits and access to content made within the last 90 days. More advanced exports and alignment options are school-plan features.
Check Diffit's current pricing.
6. Canva Education
Best for: visual classroom materials—slides, posters, infographics, worksheets and student-facing designs.
Canva Education is currently 100% free for eligible K–12 educators and students and is available globally rather than being restricted to one country. Canva says its education offer includes most premium features, LMS integrations and AI tools for teacher tasks such as quiz generation, slides and lesson planning.
Eligibility limitation: Canva Education is for eligible primary/secondary educators and institutions rather than higher-education teachers.
Check Canva Education eligibility.
7. Gemini for Education
Best for: schools using Google Workspace or institutions that want an admin-managed education AI assistant.
Google currently offers Gemini for Education at no cost for qualifying institutions, including through Education Fundamentals. Google highlights lesson planning, differentiation, assessments, practice materials and administrative writing.
Free-plan limitation: the no-cost edition has limited access to premium models and Deep Research compared with the paid Google AI Pro for Education add-on.
8. Khan Academy / Khanmigo Teacher Tools
Best for: teachers who want AI assistance connected to a large standards-aligned learning platform.
Khan Academy currently describes its classroom platform as free for teachers, students and families and includes AI-powered Khanmigo teacher support in its teacher experience. Khanmigo teacher tools include planning and other classroom workflows.
Limit to check: Khan Academy's terms note geographic and school-based restrictions for some Khanmigo teacher features, while district partnerships add additional student and administrative capabilities.
See Khan Academy for teachers.
9. Gemini Notebook
Best for: teachers who want answers grounded in their own documents rather than a general-purpose chat.
Google's education version of Gemini Notebook is free of charge for qualifying institutions and is designed to work from sources you provide. Google currently publishes free limits including up to 100 notebooks, up to 50 sources per notebook and 50 chat queries per day, plus limited Audio and Video Overviews.
Why it stands out: source-grounded responses with inline citations can be useful for curriculum documents, readings, research packets and study guides.
See Gemini Notebook for education.
Best Free AI Tools for Teachers
If “free” is the main requirement, start by checking eligibility before comparing features. U.S. K–12 teachers currently have unusually strong free offers from ChatGPT and Claude. Canva Education is free for eligible K–12 educators globally. MagicSchool, Brisk and Diffit maintain free individual-teacher tiers. Google offers Gemini for Education and Gemini Notebook at no cost for qualifying institutions.
Best AI Tool for Lesson Planning
There is no single winner for every planning style. ChatGPT and Claude are flexible general assistants, MagicSchool and Brisk offer task-specific teacher workflows, while Khanmigo and Gemini also include planning support. If you want a no-account planning structure first, use the NGSS Lesson Plan Generator.
Best AI Tool for Differentiation
Diffit is purpose-built around adapting instructional materials, while Claude for Teachers includes a dedicated differentiation skill. Gemini for Education and other general assistants can also adapt materials when given clear grade, objective and student-access requirements.
Best AI Tool for Quizzes and Rubrics
MagicSchool and Brisk both include task-specific assessment tools, while ChatGPT, Claude and Gemini can generate assessments from a structured prompt. For a local browser option that does not call an AI API, use our Worksheet Generator, Exit Ticket Generator and Rubric Generator.
How to Choose an AI Tool for Your School
- Start with the task. Pick the tool that removes the most repeated work from your week.
- Check the real free limit. “Free” can mean unlimited core tools, limited generations, or institutional eligibility.
- Check student-data rules. Vendor protections do not replace district policy.
- Test one real workflow. Compare output quality and editing time using the same lesson or assessment brief.
- Avoid unnecessary tool sprawl. One well-integrated tool can be more useful than five overlapping subscriptions.
