Show HN: I made an AI language learning tool for intermediate and above learners

So I made Lezan for myself. Whenever I was watching anime or reading manga and saw an interesting word/phrase in Japanese, I wanted something to not just translate the phrase/word but also help me practice it and see a description and examples of it.

It works by providing it a phrase/word, and then it will generate some flashcards and then afterward it will generate a quiz for you just like Duolingo.

It uses gpt-4o-mini for now, but I'm considering using 4o if I see ppl are liking it.

I would really appreciate any feedback.
