Alongside solidifying my knowledge of the Kanji themselves, I’m interested to also solidifying my knowledge of their readings, including whether a given on-yomi is Kan-on, Go-on, Tou-on, or Kan’you-on. Is there any support (officially through WaniKani or unofficially through Chrome Extensions or something similar) for me to learn this, or is this going to be more of a DIY process as I go through the course?
That info is on kanjipedia. And there is script that link kanji WK pages to the corresponding kanjipedia page
(I use it on my laptop, but I don’t remember the name right now)
