Details checked against each provider's official pages on October 9, 2026. This guide is based on that research, not on classroom testing. Plans and eligibility rules change, so check the linked official page before you rely on them.
Teachers spend hours every week on lesson plans, quizzes, differentiated worksheets and feedback. AI can take a real chunk of that work off your plate, and several of the best teacher-focused tools are free. This guide covers five options, who can use them, and what the free versions include.
Quick comparison
| Tool | Best for | Who can get it free |
|---|---|---|
| MagicSchool | Lesson plans, quizzes, rubrics | Any individual teacher (free plan) |
| Canva for Education | Worksheets, slides, class visuals | Verified K-12 teachers and their students |
| Gemini for Education | Planning inside Google Workspace | Schools on Workspace for Education |
| Khan Academy teacher tools | Practice, feedback and progress tracking | Teachers (free platform) |
| General AI chatbots | Anything else | Anyone with a free account |
1. MagicSchool
MagicSchool is built specifically for teachers. Its "Forever Free" plan for individual teachers includes 80+ teacher tools (for things like lesson plans, rubrics and worksheets), the Raina chatbot, quizzes, and class writing feedback.
- Not in the free plan: unlimited generations, unlimited output history, the 50+ student-facing tools, and student learning insights. MagicSchool doesn't publish the free plan's exact generation limit.
- Paid option: Plus is $8.33/month billed annually, or $12.99 month to month.

2. Canva for Education
If you teach K-12 (primary or secondary school), Canva for Education gives you nearly all of Canva's premium features for free, plus classroom tools such as LMS integrations, assignments and thousands of education templates. Canva says it offers classroom-appropriate AI at no cost and that it "never uses student data to train AI models."
- How to qualify: sign up with a school email or upload proof of employment. Canva says verification takes a few days.
- Students: they can't sign up on their own; a verified teacher invites them.
- Not eligible: university lecturers. The program is for K-12.

3. Gemini for Education (Google Workspace for Education)
If your school uses Google Workspace for Education, you may already have access. Google says Workspace for Education includes Gemini for Education, Gemini Notebook and Gemini in Classroom at no cost, with "enterprise-grade data protection."
- Who qualifies: the free Education Fundamentals edition is for qualifying institutions, so your school's IT admin sets it up, not individual teachers.
- Advanced features: some need the paid Education Plus edition or add-ons.

4. Khan Academy teacher tools
Khan Academy describes its rebuilt teacher platform as "still free", with "no paywalls" and "no ads." It covers math, reading, writing and science, and includes AI-powered tools to help you plan, give feedback and track student progress in one place.
- Note: the teachers page doesn't say which AI features are free in every country, so check availability where you teach.

5. A general free AI chatbot
ChatGPT, Gemini, Claude and Microsoft Copilot all have free plans that work well for teaching tasks. Some prompts to try:
- "Create a 45-minute lesson plan on [topic] for [grade], with a starter, main activity and exit ticket."
- "Rewrite this text at three reading levels for mixed-ability students." (paste the text)
- "Write 10 multiple-choice questions on [topic] with an answer key and one common misconception per question."
See what each one includes for free in our guide to the best free AI chatbots. For slides, see free AI presentation makers.
Using AI responsibly in the classroom
- Protect student privacy. Don't paste student names, grades or personal details into general chatbots. Prefer tools your school has approved.
- Check your school's policy before using AI tools with students, and check each tool's age requirements.
- Review everything. AI can get facts wrong or misjudge the level. You're still the expert.
- Keep your voice. Use AI for first drafts and ideas, then adapt them to your students.
