Cleo helps you learn Japanese vocabulary and kanji, and actually remember it.
At its core is a modern spaced repetition system, the same approach serious learners rely on. Cleo shows you each card right before you would forget it, so you spend less time on words you already know and more on the ones you don't.
Start studying in seconds with curated JLPT decks from N5 to N1, covering both vocabulary and kanji. Prefer your own list? Build a deck in seconds: type a word and Cleo fills in the reading, meaning, and examples for you with built in dictionary autocomplete.
Every card comes with clear, natural Japanese audio, so you learn correct pronunciation from day one. Turn any deck into a hands free audio loop and keep reviewing while you walk, commute, or cook. Playback continues when your screen is locked, with full play, pause, and skip controls right on your lock screen.
