MagicSchool AI
A set of AI tools built for teachers: lesson plans, rubrics, quizzes, feedback on student work, parent letters and reading-level adjustments, all as guided forms rather than a blank chat box. Widely used in K-12 schools and free to start on an individual account.
Why I recommend it: Freemium: an individual teacher account is free with monthly usage limits, and the paid plans add unlimited use plus school and district features. Two cautions — never paste a named student's work or personal details into it, and read everything it produces before it reaches a classroom or a parent. The guided forms are also worth borrowing if you write training material outside a school.
