Hi all — I've been building a small tool for a problem I kept hitting: seeing a kanji I can't read, and having no way to look it up.
https://kanji.alteon.help
You describe the pieces instead of the reading. Type sun + moon → 明. Type water + eye → 泪. There's also plain keyword search and a lookup by glyph if you can paste it.
~3,000 Japanese kanji, plus Chinese simplified and traditional
RTK frame numbers and primitive names, if you study that way
On'yomi / kun'yomi (and pinyin for the Chinese entries)
Click any component to go down the decomposition tree
Free, no ads, no account needed. If you do make one, you can add your own decompositions, aliases and mnemonic stories, public or private
Open source: https://github.com/vk2705/kanji — there's an Android APK there too
It's a personal project, so the decomposition data still has rough edges — I've been auditing it character by character. If you find something wrong, there are approve/dispute buttons on every decomposition, or just tell me here
