Envie qualquer material. O LearnBook transforma em flashcards e quizzes com cronograma de repetição espaçada FSRS — para que o que você estuda realmente fique.
Com que facilidade você lembrou este cartão?
Three modules feed each other: what you import becomes review, review becomes mastery, mastery keeps you coming back.
Import a PDF, web page, note, caption, or transcript. In seconds you get cited flashcards, a layered summary, and a quiz — each traceable to the source.
Generated cards flow straight into an FSRS spaced-repetition queue. The 21-study-day habit challenge and per-concept mastery score turn passive notes into active recall.
Streaks, XP, levels, a team leaderboard, and friend PK turn review into something you want to keep up. Every reward is bound to a real recall, not a tap.
Each phase feeds the next — review data drives weak-point drills, mastery drives your streak.
Papers, textbooks, ebooks, and manuals
Articles, documentation, and clipped references
Class notes, markdown, pasted fragments
Lecture captions and course transcripts
Long-form audio transcripts and interviews
Long-running parsing, indexing, transcript processing, quiz generation, and review scheduling run as auditable jobs so failures stay visible.
Table of contents, source text, AI Tutor, citations, notes, quizzes, and review actions work together. Every answer and practice item can return to its source.

Backed by memory science
Most AI study tools stop at generating notes. LearnBook schedules review with the same spaced-repetition science behind Anki — so knowledge compounds instead of evaporating.
The Free Spaced Repetition Scheduler tunes each card's interval to your recall speed. Concepts resurface right before you'd forget them — not a day too soon or too late.
New knowledge gets a structured first three weeks: frequent early, gradually spacing out. It flattens the forgetting curve exactly where it's steepest.
Every recall updates a per-concept mastery score. Weak points get extra drills; mastered topics quietly fade into the background.
No long waits — import to understand, understand to practice.
Your materials and notes are never used to train any AI model.
Export or permanently delete all of your learning data, anytime.
All data is protected with TLS encryption in transit.
A study aid — not a ghostwriter, and never a detection-evasion tool.
