🍎
MagicSchool AI
Free tierBest overall
MagicSchool is a teacher’s swiss army knife, with dozens of purpose-built tools: lesson plans, rubrics, quizzes, feedback, IEP helpers, and more. It is designed around real classroom needs and built with teacher privacy in mind. The free plan covers a huge amount. For teachers who want one trusted place to handle most AI tasks, MagicSchool is the clear starting point.

2. Diffit — Best for Reading Materials

📖
Diffit
Free tierBest for differentiation
Diffit solves a huge classroom challenge: adapting content to different reading levels. Paste any article, topic, or text, and it generates a leveled version with vocabulary, questions, and summaries for each student ability. This makes differentiation, which normally takes hours, almost instant. For teachers with mixed-ability classes or English learners, Diffit is transformative and mostly free.

3. Curipod — Best for Interactive Lessons

🎮
Curipod
Free tierBest for engagement
Curipod turns a topic into a full interactive lesson — slides with polls, open questions, word clouds, and activities students respond to live on their devices. It takes minutes to generate and keeps students engaged rather than passive. For teachers who want participation, not just presentation, Curipod builds the kind of lessons that hold a room’s attention, with a genuinely useful free tier.

4. Khanmigo — Best AI Tutor

🧮
Khanmigo (Khan Academy)

Khanmigo is Khan Academy’s AI tutor, designed to guide students to answers with questions rather than simply handing over solutions — a crucial difference for real learning. It also helps teachers with planning and analytics. Built with strong safety guardrails for students, it is one of the most trusted classroom AI tutors. Teachers can often access it free through Khan Academy’s education programs.

5. Google Gemini for Education — Best Free All-Rounder

🆓
Google Gemini
Free tierBest free general tool
For general tasks — drafting lesson ideas, writing parent emails, explaining concepts, brainstorming activities — a free general AI like Google Gemini is endlessly useful and integrates with Google Classroom and Docs that many schools already use. It lacks the purpose-built teacher tools of MagicSchool, but for flexible everyday help at no cost, it is a reliable companion for any teacher.
