The short answer
The best AI tools for teachers in 2026 are MagicSchool for all-round planning, Brisk for feedback inside Google Docs, and Khanmigo for standards-aligned lesson help, and all three have a free plan for individual teachers. However, if your school already pays for Google Workspace for Education or Microsoft 365 Education, start with the AI that is already built in, because your district has likely vetted it for student privacy.
- Best overall: MagicSchool (80+ teacher tools on the free plan)
- Best for grading feedback: Brisk (free Chrome and Edge extension)
- Best general chatbot: ChatGPT for Teachers (free for verified U.S. K-12 staff)
- Best if your school uses Google or Microsoft: Gemini in Classroom or Teach in the Microsoft Copilot app
- Golden rule: never paste names, grades or IEP details into a tool your district has not approved

AI tools for teachers are apps that use generative AI, the technology behind chatbots like ChatGPT, to draft lesson plans, quizzes, rubrics, differentiated readings and written feedback. In 2026, the market splits into two camps. First, there are teacher-specific platforms such as MagicSchool, Brisk and Khanmigo, which wrap a large language model in classroom templates and school privacy agreements. Second, there are the big general assistants, which now ship education editions.
This guide ranks the best AI tools for teachers by job to be done, so you can pick one for lesson planning, one for grading feedback and one for student-facing practice. Instead of hands-on test scores, every limit and price below comes from each vendor’s published plan details, checked on October 24, 2026. Plans change often, so treat the free-tier notes as a snapshot.
What Are the Best AI Tools for Teachers in 2026?
The short list is MagicSchool, Brisk, Khanmigo, ChatGPT for Teachers, Gemini in Classroom, Microsoft Teach, SchoolAI, Diffit and Curipod. Each one has a no-cost way in, but the free tiers differ a lot in what they cap, so the table below puts the limits side by side.
| Tool | Best for | Free tier | Main free limit | Paid tier | Student-facing? |
|---|---|---|---|---|---|
| MagicSchool | All-round planning | Yes, Forever Free | Generations and history not unlimited | Plus $8.33/mo billed yearly or $12.99/mo | Plus and Enterprise |
| Brisk | Feedback in Docs and Slides | Yes, 20+ tools | Batch feedback upload limit | School and district quotes only | Paid (Brisk Boost) |
| Khanmigo | Standards-aligned lessons | Yes, for educators 18+ in eligible countries | Teacher tools only | District partnerships; families pay | Paid or district |
| ChatGPT for Teachers | Open-ended drafting | Yes, verified U.S. K-12 staff | Not for students; U.S. only | Pricing may change after the free period | No |
| Gemini in Classroom | Google Classroom schools | Yes, Workspace for Education accounts | Needs a school Google account | Google AI Pro for Education add-on | Teacher-led Gems and NotebookLM |
| Teach (Microsoft Copilot app) | Microsoft 365 schools | Yes, A1/A3/A5 faculty and staff | Needs a school Microsoft license | Microsoft 365 Copilot add-on | Learning Activities, 13+ |
| SchoolAI | Supervised student chat | Yes, no expiry | 5 Space sessions per year | Pro and Scale via schools only | Yes |

Pro tip. Before you sign up for anything, ask your tech coordinator which AI tools the district has a signed data privacy agreement with. Those are the only ones you should use with real student work.
The 9 Best AI Tools for Teachers, Ranked by Use Case
Ranked by how much a classroom teacher can do on the free plan, MagicSchool comes first and Curipod rounds out the list. Also, each card says who should skip the tool, because the right pick depends on your school’s platform as much as on features.
1. MagicSchool: Top pick among the best AI tools for teachers
MagicSchool is a teacher AI platform with ready-made generators for lesson plans, rubrics, IEP drafts, quizzes and parent emails, plus a chatbot called Raina. Because the free plan already includes more than 80 teacher tools, it is the easiest single starting point for most K-12 teachers.
- Free plan: 80+ teacher tools, Raina chatbot, quizzes, class writing feedback; generations and output history are not unlimited
- Paid: Plus is $8.33 per month billed annually ($99.96 per year) or $12.99 month to month, and adds unlimited generations plus 50+ student tools
- Privacy: lists FERPA, COPPA and SOC 2 compliance; custom data privacy agreements only on Enterprise
- Skip it if: you want students to use it and your school won’t buy a license, since student tools sit on paid plans
2. Brisk: Best for grading feedback
Brisk is a browser extension for Chrome and Edge that adds an AI button inside Google Docs, Slides, YouTube and your LMS. As a result, you can draft feedback on an essay, re-level an article or turn a video into a quiz without leaving the page you already have open.
- Free plan: 20+ tools, unlimited usage on the standard model, materials in 50+ languages, glow-and-grow feedback, batch feedback with an upload cap
- Paid: Premium and Intelligence are custom-priced for schools and districts and add 35+ tools, Brisk Boost for students and admin dashboards
- Privacy: says it is FERPA and COPPA compliant and does not sell student data; SOC 2 Type II is still in progress
- Skip it if: you work on an iPad or outside a Chromium browser, because Brisk lives in the extension
3. Khanmigo: Best for standards-aligned lesson plans
Khanmigo is Khan Academy’s AI assistant, and its teacher side is free with sign-up for educators aged 18 and over in eligible countries. Notably, its lesson plans tie into Khan Academy’s own content library, so the output tends to point at practice students can actually do next.
- Free for teachers: lesson planning, learning objectives, rubrics, exit tickets, quiz questions, student groupings, hooks and summaries of recent student work
- Paid: students and families pay a monthly or annual fee (U.S. billing address); schools buy through district partnerships
- Skip it if: you teach a subject Khan Academy barely covers, since much of its value comes from that library
4. ChatGPT for Teachers: Best general-purpose assistant
ChatGPT for Teachers is OpenAI’s education workspace for U.S. K-12 staff, launched in November 2025. It is free for verified teachers, staff, school leaders and district administrators at accredited U.S. K-12 schools, and OpenAI’s help center says information shared in it is not used to train models by default.
- Free period: OpenAI’s help center currently lists free access through June 2028 (the launch post originally said June 2027); pricing may change after that with advance notice
- Sign-up: verify at chatgpt.com/k12-verification with a school or district email
- Skip it if: you teach outside the U.S. or want a student-facing tool, because the plan is for staff only
5. Gemini in Classroom: Best for Google Classroom schools
Gemini in Classroom is Google’s set of more than 30 AI features inside Google Classroom, free for educators with Google Workspace for Education accounts since June 2025. For example, it drafts a lesson plan from a grade and topic, builds a quiz you export to Google Forms and generates rubrics.
- Free: lesson plans, quizzes, rubrics, lesson hooks, teacher-led Gems and NotebookLM study guides for students
- Paid: Gemini inside Docs, Sheets and Slides and premium features come through Google AI Pro for Education
- Skip it if: your school runs on Microsoft 365, or you only have a personal Gmail account
6. Teach in the Microsoft Copilot app: Best for Microsoft 365 schools
Teach is Microsoft’s educator hub inside the Copilot app, and Microsoft says it does not require a paid Copilot license. Instead, it is on by default for faculty and staff with Microsoft 365 A1, A3 or A5 (or Office 365 A1, A1 Plus, A3 or A5) licenses with Copilot Chat enabled.
- Free: lesson plans and rubrics saved as Word files, Forms quizzes, flashcards, reading-level and standards adjustments
- Students: Learning Activities practice works for students; generation is off for under-18s by default and unavailable under 13
- Skip it if: you have a personal Microsoft account, since Teach is not offered to consumer accounts
7. SchoolAI: Best for supervised student chat
SchoolAI lets teachers build Spaces, guided AI chats for students that the teacher can watch in real time. Its free plan never expires, but it now caps you at five Space sessions per year, so it works as a pilot rather than a daily tool unless your school buys Pro.
- Free: uncapped teacher chat with its assistant Dot, tools and assistants, most PowerUps, student chat observability and critical alerts
- Paid: Pro and Scale are sold only to schools and districts; there is no individual paid plan
- Skip it if: you need students on it every week and your school won’t buy a plan
8. Diffit: Best for leveled readings
Diffit turns a topic, article or video into reading passages at different levels, with vocabulary and questions attached. Consequently, it is a fast way to differentiate one text for an entire mixed-ability class.
- Free (Basic): create, edit, print, share and download to PDF; you can only access content from the last 90 days
- Paid: school licenses priced by enrollment, plus individual licenses; adds Google, Canva and Microsoft exports, standards alignment and full history
- Skip it if: you want to build a reusable resource library without paying, because of the 90-day window
9. Curipod: Best for student writing practice
Curipod runs live writing sessions where students answer prompts and get AI feedback that the teacher reviews first. In addition, it deliberately has no student chatbot, and it says student and teacher data are not used to train AI models.
- Free: unlimited student writers, a limited number of live sessions that renew weekly, responses up to 1,000 characters
- Paid: School and District plans are custom-priced by student count and add PDF downloads, reports, SSO and bilingual writing
- Skip it if: you need long essays scored, since free responses stop at 1,000 characters
Which Free AI Tools for Teachers Are Actually Free?
All nine tools above have a free way in, but only a few are generous enough for daily use. In short, MagicSchool, Brisk, Khanmigo’s teacher tools and the school-licensed Google and Microsoft features are the free AI tools for teachers you can lean on every day, while SchoolAI and Curipod free plans are better for trying the idea first.
Is MagicSchool AI free for teachers?
Yes. MagicSchool’s own pricing page labels its individual teacher plan Forever Free. However, unlimited generations and output history are Plus features, and student tools need Plus or a school Enterprise plan.
Is Brisk free for teachers?
Yes. According to the Brisk plans page, the free plan for individual teachers includes 20+ tools with unlimited usage on its standard model. The paid tiers are sold only to schools and districts, so there is no individual upgrade to buy.
Can teachers use ChatGPT for free?
Yes, in two ways. Any teacher can use the regular free ChatGPT, but verified U.S. K-12 educators can get ChatGPT for Teachers at no cost, which OpenAI’s help center describes as a workspace whose content is not used for training by default. Because it is built for schools, it is the better choice of the two.
What Is the Best AI Lesson Plan Generator?
For most teachers, the best AI lesson plan generator is MagicSchool or Khanmigo, because both start from grade, standard and objective rather than a blank chat box. Still, if your district runs Google or Microsoft, the built-in planners are a strong second choice since they save straight into Docs, Forms or Word.
| Lesson planning need | Best pick | Why |
|---|---|---|
| Free AI lesson plan generator, any platform | MagicSchool | Dedicated lesson plan, unit plan and rubric generators on the free plan |
| Standards-aligned plans with practice | Khanmigo | Plans tied to Khan Academy content; free for teachers |
| Plans that drop into Google Classroom | Gemini in Classroom | Drafts plans and Forms quizzes inside Classroom |
| Plans saved as Word documents | Microsoft Teach | Guided plans and rubrics saved to Word |
| Worksheets and leveled texts | Diffit | Leveled passages with questions, PDF download free |
| Custom or unusual lessons | ChatGPT for Teachers | Open-ended prompting for anything templates miss |
How to get a usable lesson plan from AI
- First, give the grade, subject, exact standard code and lesson length.
- Next, describe your class in general terms, such as several English learners or a wide reading range, without naming students.
- Then ask for a hook, guided practice, an exit ticket and one differentiation idea.
- Finally, check every fact, date and answer key yourself before it reaches students.
Can AI Grade Student Work? AI Grading Tools for Teachers
AI can draft feedback and suggest rubric scores, but the teacher should still assign the grade. That is also how the main AI grading tools for teachers are built: Brisk, MagicSchool’s class writing feedback and Curipod all produce suggestions you review, while Curipod requires teacher review before students see output.
For essays, Brisk is the most convenient free option because it works inside the Google Doc a student already shared with you. Meanwhile, Curipod is better for short, frequent writing practice, and Microsoft Teach or Gemini in Classroom can generate the rubric you grade against.
Watch out. Student essays are often education records. So, only run them through a grading tool your school has approved, remove names first where you can, and never let an AI score be the final grade without your own read.
Should teachers rely on AI detectors?
Treat an AI detector score as a reason to talk with a student, not as proof. Instead of policing, many teachers now design assignments with drafts, in-class writing and short oral check-ins, which makes the question matter less.
Is It Safe? Student Privacy Rules for AI Tools for Teachers
AI tools are safe to use with students only when they meet two U.S. laws, FERPA and COPPA, and your district has approved them. In practice, that means using tools covered by a district agreement and keeping identifiable student data out of anything else.
FERPA in plain English
FERPA, the Family Educational Rights and Privacy Act, gives parents rights over their children’s education records, including some control over sharing personally identifiable information, according to the Department of Education’s Student Privacy site. Those rights pass to the student at 18. Similarly, the Department’s July 2025 guidance on AI in schools says AI systems used with federal funds must comply with federal privacy laws, including FERPA.
COPPA in plain English
COPPA, the Children’s Online Privacy Protection Act, protects children under 13 online. The FTC’s COPPA FAQ says a school can consent on a parent’s behalf, but only for the school’s educational use. If a company uses student data for its own commercial purposes, such as advertising, it needs a parent’s consent instead.
| Before you use an AI tool with students, check | Why it matters |
|---|---|
| Is it on your district’s approved list? | Approval usually means a signed data privacy agreement |
| What is the minimum age? | COPPA covers under-13s; many tools limit features for minors |
| Does it train on your data? | Curipod and ChatGPT for Teachers say no by default |
| Can students chat freely? | Teacher-monitored tools like SchoolAI or none, like Curipod, are safer for kids |
| Can you delete student data? | COPPA gives schools the right to review and delete a child’s data |
How Should Teachers Use AI in the Classroom Responsibly?
Use AI to draft, and use your own judgment to decide. Because every tool on this list can produce confident mistakes, the safest routine is simple: generate, check, edit, then share.
- Keep it anonymous: describe needs, not names, in any tool outside your district’s approved list.
- Fact-check everything: answer keys, dates, quotations and math steps are where errors hide.
- Tell families: the Department of Education’s AI guidance stresses transparency so parents understand how tools are used.
- Teach AI literacy: show students when AI is allowed and how to cite it, then point older students to free AI tools for students that fit your rules.
- Keep the human role: the same federal guidance encourages AI that supports educators without replacing them.

Our verdict
If you only try one of the best AI tools for teachers, make it MagicSchool, since its free plan covers the most everyday planning jobs. Then add Brisk if you grade in Google Docs, and claim ChatGPT for Teachers if you are a verified U.S. K-12 educator.
That said, your school’s existing platform should break any tie. Gemini in Classroom and Microsoft Teach cost nothing extra, sit inside tools you already use and are far more likely to be covered by your district’s privacy agreements. For student-facing AI, wait for a school license to SchoolAI, Curipod or MagicSchool rather than stretching a free plan.
Frequently Asked Questions
What is the best AI tool for teachers?
MagicSchool is the best all-round AI tool for teachers for most people, because its free plan includes more than 80 teacher tools for lesson plans, rubrics, quizzes and parent emails. However, if your school already uses Google Workspace for Education or Microsoft 365 Education, try Gemini in Classroom or Microsoft Teach first, since they are included at no extra cost.
Are there free AI tools for teachers?
Yes. MagicSchool, Brisk and Khanmigo all have free plans for individual teachers, and verified U.S. K-12 educators can use ChatGPT for Teachers at no cost. In addition, Gemini in Classroom and Teach in the Microsoft Copilot app are free with eligible school accounts. SchoolAI, Diffit and Curipod also have free tiers, but with tighter limits.
Is MagicSchool AI free for teachers?
Yes. MagicSchool offers a Forever Free plan for individual teachers with more than 80 teacher tools, the Raina chatbot, quizzes and class writing feedback. However, generations and output history are not unlimited on the free plan. MagicSchool Plus costs 8.33 dollars a month billed annually or 12.99 dollars month to month and adds student tools.
Can teachers use ChatGPT to grade papers?
Teachers can use ChatGPT to draft feedback or check work against a rubric, but they should keep the final grade decision themselves. Also, student essays can count as education records under FERPA, so use only tools your district approves, such as ChatGPT for Teachers if your school allows it, and remove student names wherever possible.
What is the best free AI lesson plan generator?
MagicSchool and Khanmigo are the best free AI lesson plan generators for most teachers, because both build plans from grade level, standards and objectives. If your school uses Google Classroom, Gemini in Classroom drafts plans and quizzes inside Classroom, while Microsoft Teach saves guided lesson plans as Word documents for Microsoft 365 schools.
Are AI tools for teachers FERPA compliant?
Some are, but compliance depends on how your school uses them. MagicSchool and Brisk say they are FERPA and COPPA compliant, and ChatGPT for Teachers is built for U.S. schools. Still, the safest approach is to use only tools covered by your district’s data privacy agreement and to keep identifiable student information out of everything else.
