Which AI tool should a teacher use? A plain-language guide for 2026

Free teacher editions from OpenAI, Google and Anthropic, Microsoft Copilot through your school account, and teacher-specific platforms — how to choose without getting lost.

By Teacher Tools · · 3 min read

There are now more AI tools aimed at teachers than anyone could try in a year. The good news: for most teachers, the choice comes down to a few questions, and several of the biggest assistants now offer free versions built for education.

We’re not affiliated with any company mentioned here, and nothing in this post is sponsored. Product details change often — check each provider’s current terms before you sign up.

Start with three questions

  1. What does my school or district already provide or approve? If there’s an approved tool, use it for school work. It likely comes with a data agreement your district has reviewed, and your IT team can support it.
  2. Where do I already work? If your school runs on Google Workspace, Gemini is built into the tools you use daily. If it runs on Microsoft 365, Copilot is. Fewer accounts and less copy-pasting is a real time saver.
  3. What are the privacy terms? Look for a clear commitment that your conversations aren’t used to train the company’s models, and for education-specific protections such as a student data agreement.

General assistants with education versions

These are full-featured AI assistants: they can draft, rewrite, brainstorm, analyze documents you upload, and more.

ChatGPT for Teachers (OpenAI)

OpenAI offers ChatGPT for Teachers free to verified U.S. K–12 teachers through June 2027. It includes the full ChatGPT feature set (file uploads, search, image tools, data analysis and shared workspaces). OpenAI says data shared there isn’t used to train its models by default, and districts can add administrative controls.

Gemini for Education (Google)

For schools on Google Workspace for Education, Google includes Gemini for Education at no additional cost, along with Gemini features inside Google Classroom for tasks such as lesson planning, vocabulary lists and differentiated materials. Google states that education users’ data isn’t used to train its models or reviewed by humans for model improvement. Whether it’s turned on is up to your school’s Workspace administrator.

Claude for Teachers (Anthropic)

Anthropic launched Claude for Teachers in July 2026: free premium access for verified U.S. K–12 educators, with a year of access for anyone who signs up by June 30, 2027. It includes lesson planning aligned to state standards, differentiation tools, integrations with several education platforms, and the ability to schedule recurring tasks. Anthropic states it never trains its models on Claude for Teachers conversations and covers student information with a K–12 data processing addendum.

Microsoft Copilot (through your school account)

Many schools on Microsoft 365 give staff access to Copilot Chat through their school account, often with enterprise data protections. Availability and features depend on your district’s license — ask your IT team what’s enabled.

Teacher-specific platforms

A second category is platforms built specifically for teachers, such as MagicSchool, Brisk Teaching, Diffit and Khanmigo. Instead of a blank chat box, they offer ready-made tools — “make a rubric,” “level this text,” “write report card comments” — with forms designed around teaching tasks. Some run inside your browser alongside Google Docs or Slides.

They can be faster to learn than a general assistant, and many offer free tiers. The trade-off is that you’re limited to the tools they’ve built, and you’re adding another account and another privacy policy. Check whether your district has an agreement with the provider before you use one with any student-related content.

Which one should you pick?

  • Your district provides one: use it. That’s usually the end of the decision.
  • You’re on Google Workspace: try Gemini first — it’s already where your documents are.
  • You’re on Microsoft 365: check what Copilot access your account has.
  • Neither, or you want a dedicated assistant: ChatGPT for Teachers and Claude for Teachers are both free for verified U.S. K–12 teachers right now. Try the same three tasks in each — a worksheet, a leveled passage, a rubric — and keep whichever fits the way you work.
  • You want buttons, not prompts: a teacher-specific platform may suit you better.

Honestly, the differences between the top assistants matter less than how you use them. Clear prompts with context, careful checking, and no student data will get you good results in any of them. Our starter guide and prompt builder work with every tool on this list.
