Powered by FSRS — modern spaced-repetition science

Free core, forever · No card limits · iOS, Android, web & desktop
One card, on cadence
Each correct answer pushes the next review further out — dense at first, then spaced wide. That widening beat is the cadence.
Language-first, not generic
Everything a language asks of a flashcard — built in.
FSRS, auto-tuned
An open, research-backed free-spaced-repetition scheduler, tuned to your own review history. Grade-A retention with zero interval-fiddling.
Native-speaker audio
Real voices on every card, with instant text-to-speech fallback for any word you add. Hear it the way it's meant to sound.
Pronunciation feedback
Record yourself, compare against the native take, and get speech-recognition scoring on the sounds you keep missing.
Scripts & diacritics
Kanji stroke order, hanzi, accent marks, right-to-left — handled as first-class citizens, not afterthoughts.
Auto-generated cards
Type a word; get the definition, an example sentence, audio, and gender or conjugation pulled in automatically.
Conjugation & grammar
Built-in card types for verb tables and grammar patterns — the parts of a language generic flashcards quietly ignore.
Sentence mining
Paste an article or a subtitle file and turn every unknown word into a ready-to-study card in one pass.
