Generate a full set from a one-line prompt. Study with spaced repetition. Works offline. Syncs across devices.
Describe any topic and the app builds a full flashcard set in seconds. Edit, study, or share — it's yours.

FSRS schedules every card for the exact moment you'd start to forget. No grinding, just the right review at the right time.

Learn with spaced repetition, browse the whole set, shuffle for random review, or test yourself by typing answers. Different brains, different ways.
