Remember kanji by the story inside them.

Kanjihook breaks every kanji into familiar parts and gives you a mnemonic you won't forget.

休
亻木

A person leans against a tree to rest.

キュウ · やす(む)

A story for every kanji

Each character is split into parts you already know and tied together with a short, memorable mnemonic.

Write your own

Replace any mnemonic with one that sticks for you. Your version always shows first.

Review at the right time

Kanji come back just before you'd forget them, so daily practice stays short.
