KANJIBOX IS SMART
— — — — — — — — — — — — —
KanjiBox adapts to your performance by prioritising items you struggle with, and reducing repetition of material you already know. As you progress, it will introduce new kanji and vocabulary, but always while following your pace.
Spend more time on what needs work, and less time reviewing what you have already mastered.

KANJIBOX IS A MEAN TEACHER
— — — — — — — — — — — — —
Behind the deceptively simple Multiple Choice Question format, is a well-oiled algorithm designed to trip you up: similar-looking kanji, subtle pronunciation differences, closely-related grammatical words…
Because the goal is to learn the language, not how to beat the test.

KANJIBOX IS ENGAGING
— — — — — — — — — — — — —
Exhaustive stats across levels and categories show you what you have mastered, what needs more practice, and how your results improve over time. Quiz mode adds a fun competitive element to your studying.
Because serious should not mean tedious!
