I’m working on this with Manabi Reader for Japanese

https://reader.manabi.io

It has Anki integration or its own SM2 flashcards app (soon FSRS). And it passively collects a personal corpus of sentences from any web/ebook material you open (manga up next).

I plan to add more sophisticated sync between the reading and reviewing such that cards can be more dynamically based on relevant personal corpus content, and where reading (on the web or in books, outside flashcards) would auto-review any flashcards you have (or which you create in the future).

There really shouldn’t be any difference between encountering a word in something you’re reading and reviewing it on a flashcard. And it would be nice to revisit reading material with guidance from FSRS, to find N+1 sentences for learning new words and to find excerpts containing words that are due for review.
