Flashcard Study Tool
Build flashcard decks and study with spaced repetition (SM-2 algorithm). Tracks your progress, schedules cards by difficulty, and saves everything to localStorage.
Study smarter with SolveBar's Flashcard Tool. Create decks, flip cards to test yourself, and use spaced repetition to review cards at the optimal time based on how well you know them. Progress and scheduling saves to localStorage — a free Anki alternative in your browser.
How spaced repetition works
Spaced repetition is the most evidence-backed study technique in cognitive science. Cards you struggle with appear more frequently, cards you know well appear less often. The SM-2 algorithm calculates the next review date based on your performance rating.
Creating effective flashcards
Each card should test exactly one fact. Break complex topics into atomic facts rather than combining multiple concepts on one card. Write cards in your own words — transcribing from a textbook produces worse retention than active reformulation.
Study session best practices
Study in shorter, more frequent sessions rather than marathon cramming. 20-30 minutes daily outperforms 3-hour sessions once a week for long-term retention. Rate cards honestly — inflating your rating delays cards inappropriately and defeats the algorithm.
Frequently Asked Questions
Is this compatible with Anki decks?
Not directly — Anki uses a proprietary format. You can manually recreate decks or use the import feature if your cards are in a supported CSV format.
How many cards can I have per deck?
No limit. However extremely large decks (500+ cards) benefit from being split into sub-topics for more focused study sessions.
What does the difficulty rating mean?
After flipping a card: Again (complete blackout — show again soon), Hard (significant difficulty — short interval), Good (correct with effort — normal interval), Easy (instant recall — long interval).
