What 20 AI tools give teachers for free, read on each company's own pages: which you can use alone, which check that you teach, and which come only with your school's account.

Checked by hand on 16 October 2026, on each company’s own pages.All 79 quotes re-checked 23h ago and still there.

The short answer

If you read nothing else, read this.

  • Free for any teacher, no school plan: MagicSchool gives 20 AI uses a week. Brisk is a free Chrome and Edge extension with 20+ tools. Khanmigo's teacher tools are free in nearly every country, and SchoolAI, Diffit and Eduaide have free plans too.
  • No cap for teachers: SchoolAI puts no cap on teacher chat, Tools and Assistants. Curipod lets you build lessons without limits, with 2 class sessions a week. K-12 teachers Canva has checked get its standard AI tools as much as they like.
  • Only for verified US K-12 teachers: ChatGPT for Teachers is free through June 2028, with unlimited messages. Claude for Teachers gives a full year free if you sign up by June 30, 2027. Both check your school email. Teachers at colleges or outside the US cannot get them.
  • Free with your school's account: Gemini for Education and Gemini in Classroom are free when your school uses Google Workspace for Education and an admin turns Gemini on. Copilot Chat is free on a school Microsoft 365 A1, A3 or A5 account. You cannot switch these on alone.
  • Free AI grading and feedback: CoGrader grades 150 student submissions a month free. Class Companion gives students instant AI feedback on its free teacher plan. Curipod gives every student feedback, in 2 free class sessions a week.
  • For students: free on Canva (when you invite them), Curipod (no student accounts), Brisk Boost, Wayground, Kahoot, Formative and Class Companion. MagicSchool student rooms need Plus, Khanmigo for students needs a district partnership or a paid plan, and the ChatGPT and Claude teacher plans are not for students.
  • Free with a catch: Kahoot's free plan has no AI tools. Twee gives 5 trial runs, Padlet 3 active padlets and Conker 5 shared quizzes. Wayground's own pages disagree on how much AI free accounts get.

New accounts get 30 days of Plus first, then move to Free, which has no exports, though its help center lists the Presentation Generator as exportable on Free. Plus has unlimited uses, with caps for extreme cases. Its pricing page and a help page put student rooms on Plus, but another help page lists student tools under Free, so check in the app.
