Kanji you canactually remember.
A mnemonic story for every one of 2,000+ characters. Each character is built from parts, and the parts are tied together with stories. Lessons are laid out by JLPT level from N5 up to N1. A probabilistic SRS adapts to your pace so reviews don't pile up.
JLPT N5 kanji, and the radicals and supporting characters they need, are free.
A story you can remember is a character you keep.
A large cartoon mouth (口) with four (四) teeth and a pair of stocking (儿) covered legs sticking out.
This is one of 2,000+. Tap any part for its own story, follow it into the constellation to see what else it builds, then write the character out in the correct stroke order.
Nothing about a character is arbitrary.
時 (time) is 日 beside 寺, and 寺 is 土 over 寸, which is 十 plus a single stroke. Open the composition tree on any kanji and it unfolds that far every time, down to the last stroke.
Every node is a character in its own right, so you can tap through to its readings, its story, and the other kanji built from it.
All 2,000+ in one sky, and the ones you know are lit up.
Every character has a place in a single map, wired to the components it shares with its neighbours. The kanji you have studied burn bright; the rest stay dim until you reach them.
It is also how you explore: search a character, land on its star, and follow the lines out to everything built from it.
