- Pull known kanji from WaniKani
Background:
Learning by reading is the best approach, supported by many actual researchers (unlike me), one example is Steve Kaufmann (check his youtube).
Wanikani is a paid tool that teaches kanji over time using their own repetition system. This tool has a simple API that can let you, with a user generated key, pull all the kanji the user has currently learnt.
Value: Combining your amazing plugin to get the text in japanese from videos, with the progress a user has made over time. Allows a very powerful learning experience, as you not only learn a new kanji, but then you see and learn how its actually used (from the videos + your scripts). Of course this will increase people that pay for your auto-generated subtitles.
