The Best AI Tools for Teachers

Teachers spend hours on prep that AI can shrink to minutes: lesson plans, slides, worksheets, differentiated versions, quizzes. Used thoughtfully, it gives you back time for actual teaching. Here are the tools that help most, and how to use them responsibly.

Lesson plans, quizzes and differentiation

ChatGPT and Claude are the core: draft lesson plans aligned to your objectives, generate quizzes, create differentiated versions for different levels, and rephrase explanations. Always review for accuracy, AI can be confidently wrong, so you stay the expert in the room.

Lesson slides and decks: Gamma

Gamma turns a topic or outline into a clean slide deck in minutes, perfect for lesson presentations and unit overviews without spending an evening in slide software.

Worksheets, visuals and handouts: Canva

Canva has huge education template libraries for worksheets, posters, handouts and classroom visuals, with simple editing and built-in AI to speed up first drafts.

Research and reliable sources: Perplexity

Perplexity gives cited answers, useful for prepping content and finding sources you can verify, which matters when accuracy is part of the job.

Feedback and writing support: Grammarly

Grammarly helps with clarity and consistency in your own materials and communications, and can support writing instruction, used as a tool, not a substitute for teaching the skill.
