This extension replaces kana in etoeto by known Kanji from Wanikani
Add your WaniKani api key in the chrome extensions options.
It will convert kana into kanji you know from WaniKani (depending on your level):
- It does not convert single kana (に into 二)
Warning: It's a proof of concept, I have not made any caching and since it is only based on the kana, you might get another character that uses similar kana.
