Master Chinese characters.
Look up any word. FluentBits handles the rest: FSRS spaced repetition, character decomposition, native audio.
Understand every character
Every word broken into its radicals and components. See why 明 (bright) is 日 (sun) + 月 (moon).
See how words connect
Deep context for every word you look up: example sentences, usage notes, common pairings, and cultural background.
Picks that learn from you
Every morning, 15 words picked for your level and what you've been studying. Open the app, browse today's list, add what you want to learn.
Learn what you choose
No fixed lessons. Look up any word and FluentBits adds it to your spaced-repetition queue.
Know where you stand
Organized by HSK level, topic, and part of speech. Review stats show exactly what to study next.
Structured from day one
FSRS spaced repetition, the algorithm that outperforms Anki's SM-2 in independent research. You review each word at the exact moment you're most likely to forget, so nothing slips away.
