Cleo: Japanese that Sticks

Learn Japanese that sticks. Spaced repetition, native audio, and JLPT decks from N5 to N1, plus hands free audio loops for review anywhere you go.

Learn Japanese vocabulary and kanji, and actually remember it.

Cleo is built on modern spaced repetition, the same method serious learners rely on. It shows you each card right before you would forget it, so you spend less time on what you already know and more on what you don't.

STUDY YOUR WAY Start in seconds with curated JLPT decks, N5 to N1, covering vocabulary and kanji. Or build your own: type a word and Cleo fills in the reading, meaning, and examples with built in dictionary autocomplete.

LEARN BY EAR Every card has clear, natural Japanese audio. Turn any deck into a hands free audio loop and keep reviewing while you walk, commute, or cook. It keeps playing when your screen is locked, with play, pause, and skip on the lock screen.
