How this list works: Numbered picks are chosen by our editors and are never for sale. We may earn a commission from some links. Full disclosure.
The right AI tools for teachers don’t replace your judgment. They take over the repetitive parts of the job, such as drafting lesson plans, building quizzes, adapting texts for different readers and writing feedback, so you can spend your time on students. We reviewed the most popular options and picked the five that are worth trying in 2026. All five have a free plan or free teacher access, so you can test one before paying for anything.

#1: MagicSchool AI
The most complete all-in-one platform, with 80+ ready-made tools for lesson plans, rubrics, quizzes and parent emails. The free plan is genuinely usable, but its generation limit isn't published and the output still needs editing.
#2: Brisk Teaching
A free Chrome extension that works inside Google Docs, Slides and Classroom. Teachers praise its rubric-based feedback most, though it runs only on desktop Chrome or Edge and the free plan's limits are unclear.
#3: Diffit
Turns any text into versions at different reading levels, with vocabulary and questions. Reviewers rate its leveling as the best in the category, and it collects no student data, but it does only this one job.
#4: Curipod
Generates lessons where students answer polls, draw and write responses live on their own devices. The free plan covers real lessons, but you'll need devices in class and should check the AI's facts.
#5: Khanmigo for Teachers
Khan Academy's free AI assistant for lesson plans, rubrics, exit tickets and differentiation, available to teachers in nearly every country. Expect useful first drafts rather than polished material.
How we chose these tools
We looked at four things: what each tool does well and where it falls short, how much you get for free, what teachers and independent reviewers say about it, and how it handles student privacy. Our rankings are based on official documentation and pricing, teacher reviews and community discussions, and independent write-ups. We have not run our own classroom trials, and each review says so. Scores are editorial judgments, and we update them when products change.
Quick picks
Best all-in-one: MagicSchool AI is the safest starting point if you want one platform for planning, assessment and communication.
Best for feedback: Brisk Teaching puts rubric-based feedback and quiz tools directly inside the Google apps you already use.
Best for mixed reading levels: Diffit adapts one text into several levels and is especially useful for English learners.
Best for engagement: Curipod turns a topic into a lesson where every student responds.
Best free planning help: Khanmigo offers structured planning tools at no cost, with a strong fit if you use Khan Academy.
Which one should you choose?
Start with the job that costs you the most time. If it’s writing feedback on student work, try Brisk. If your class has a wide range of reading levels, try Diffit. If you need general planning and paperwork help, try MagicSchool AI or Khanmigo, and compare their output on the same task. If your lessons feel too passive, try Curipod.
Many teachers end up using two tools, such as MagicSchool AI for planning and Diffit for reading levels. Because each has a free plan, you can combine them without paying.
Using AI safely in your classroom
Always read AI-generated material before you use it. Lesson plans, quiz answers and facts can contain mistakes, and simplified texts can lose important details. Treat every output as a first draft.
Before using any tool with students, check your school’s or board’s policy on AI and student data. Don’t enter student names, medical details or other personal information into a tool your school hasn’t approved. Diffit is teacher-only and collects no student data, while tools with student-facing features, such as Curipod, collect student responses, so read their privacy terms first.
Frequently asked questions
Are AI tools for teachers free?
All five tools here have a free plan or free teacher access, but the limits differ. MagicSchool AI’s free plan has no expiry but doesn’t publish a generation limit. Brisk offers 20+ tools free, with unclear usage limits. Diffit has a free version plus a 60-day Premium trial. Curipod’s free plan limits AI usage. Khanmigo’s teacher tools are free in nearly every country.
Should I use ChatGPT instead?
A general chatbot is flexible but starts from a blank prompt every time. Teaching-specific tools give you ready-made templates for lesson plans, rubrics and quizzes. Discussions among teachers suggest many use both, with a dedicated tool for routine documents and a general chatbot for brainstorming.
Can AI replace teachers?
No. These tools help with preparation and paperwork. Teaching itself, including relationships, judgment and responding to students in the room, still depends on the teacher.
Do these tools work outside the US?
Khanmigo’s teacher tools are available in nearly every country, with a few regional exceptions, and Hindi is among its fully quality-tested languages. Some tools are built around the US school system, so check that grade levels and standards options fit your curriculum.
Which tool is best for English learners?
Diffit is the strongest choice for adapting texts to reading levels and languages. Always have a fluent speaker check translations before classroom use.
