Spaced repetition
Every quiz question you answer gets scheduled using the SM-2 spaced-repetition algorithm — the same method used by Anki, the world's most effective flashcard app. Items you get wrong come back the next day. Items you nail get spaced out by weeks, then months.
Everything you need to turn any YouTube tutorial into a structured learning experience — set up in under 2 minutes.
Add the LearnAnythingAI Chrome extension from the web store. One click, no config.
Navigate to any YouTube tutorial — coding, design, cooking, music, math, anything.
Click "Generate Classroom" in the extension panel. AI builds your course in ~30 seconds.
Watch with your syllabus, take quizzes, get assignments, and do daily spaced reviews.
