Recall — spaced repetition tutor

Recall turns any PDF, article link, or pasted text into a personalized study course — then quizzes you at exactly the moment you're about to forget it. WHAT IT DOES Give Recall a PDF, a web link, or a block of pasted text. It reads the material, keeps any questions you or the author already wrote, turns clear definitions and statements into flashcards, and leaves equations and formulas exactly as written — never guessed at or blanked out. Recall then builds a review schedule based on the spacing effect: short intervals at first, widening as you prove you remember. Sessions take minutes, timed to your day. WHY SPACING WORKS Most of what you read is gone within a week. Spaced repetition fixes that by reviewing material right before you'd normally forget it, on a schedule tailored per card rather than per deck.
