Spaced repetition
Review material at increasing intervals instead of repeating everything at once.

An AI flashcard maker turns your own study material into editable question-and-answer cards. GoodOff identifies the important ideas in a PDF, notes, slides, lecture or web page, then schedules each card with FSRS spaced repetition so the right review returns before the memory fades.
Choose the source-specific workflow you need. Your generated cards stay connected to the material in your GoodOff library.
FSRS uses each rating to estimate when a card should return. Difficult cards come back sooner. Strong memories wait longer. Your review queue stays focused instead of becoming another pile of work.
Review material at increasing intervals instead of repeating everything at once.

Study the cards the scheduler says are due today.
