Use case · Spaced repetition
Brainfy uses spaced repetition to show each flashcard at the moment you’re about to forget it — so cards you know fade into the background and the ones you miss come back sooner. Build decks by hand, import them, or let the AI draft them from your notes.
Cramming fights forgetting with brute force. Spaced repetition works with your memory instead: each correct review pushes the next one further out (a day, then a week, then a month), while a miss resets the card to short intervals. The result is durable recall for a fraction of the review time.
After flipping a card you tap Again, Hard, Good, or Easy — the same four-button scale serious learners rely on.
An SM-2-style algorithm grows the interval for cards you know and collapses it for cards you miss, with a daily cap so new decks never bury you.
Your home screen surfaces exactly the cards due today — no more, no less — so a session stays short and finishable.
Yes. The spaced-repetition engine — scheduling, the four-button rating, and daily review queue — is free during beta with no deck limits.
An SM-2-style algorithm (the family Anki popularised): correct reviews grow the interval via an ease factor, misses reset it, and new cards are capped per day so you don’t burn out.
Yes — paste or upload CSV, tab-separated, Anki plain-text, or Quizlet exports from any deck’s Cards tab, and they slot straight into the schedule.
No. You can write cards by hand, import them, or let the AI generate a deck from your notes, a PDF, or a photo — all three feed the same SRS.
