## What is Cleo?

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.
