I contacted the people at Japanese.io because I think it would be an amazing tool if we can selectively add furigana based on our WaniKani level. We could build our personal libraries of reading material, tailored to our levels, in a nice clean environment.
They seemed interested in supporting this for WaniKani and I’d like to make it as easy as possible for them to get started.
The question: Who / where can I point them to?
(A) For a maintained list of kanji by WaniKani level? This would be for a simple solution where you would select your level manually and they would add furigana accordingly.
(B) To incorporate an API that will maintain updated lists of WaniKani kanji for each user? Satori Reader does this to selectively add furigana based on WaniKani level. I found this API page, but doesn’t appear to be public.
