Fulin Flashcard: browser spaced repetition for language vocabulary
Fulin Flashcard is a free, offline-capable browser tool from Fulin Labs. Create or paste custom vocabulary, review it with transparent spaced-repetition intervals, and download vocabulary as CSV or share a deck link. Decks and review history are stored in this browser, so clearing site data can remove them and automatic cross-device sync is not provided.
