I'm working on etoku (https://etoku.app), what I believe is the most efficient and fun way to learn Japanese. You pick the works (TV, movies, books) that you want to understand and each new card is a sentence from native content with one word or grammar point you don't know yet. All of the cards have audio and a screenshot. Nothing is AI generated, everything is taken from real native content.

The platform isn't ready for real usage yet. I keep reworking the "course" (I curated the first 150 concepts because the most frequent concepts in native material don't make a great intro to the language).

I'm scraping lots of content and improving the analyzer (breaking a sentence down into the concepts needed to understand it) right now!

I love talking about language learning! If you're interested in the platform let me know at will @ <the domain>.
