Open-source alternative to Duolingo for learning anything

I built an open-source tool for learning anything using AI:- Type what you want to learn - It creates a full interactive course for youMove from beginner to mastery of any subject, even complex things like Quantum PhysicsIt has three formats:- Explanation: bite-sized lessons that you swipe like TikTok/Instagram - Practice: solve problems in real-world situations - Quiz: test your knowledge in Duolingo-like lessons - Language courses have a different format covering vocabulary, reading, and listening skillsIt's more hands-on than reading a long textbook or watching a videoPlus, it uses everyday language, so it's easier to connect complex concepts to your reality. I built the tool I wish I had when I was in school/uniOf course, I'm biased but I've been using it for the past few weeks and I'm truly loving it. I can't imagine myself going back to learning through traditional waysIf you have some spare time, please give me your brutal feedback. No need to be soft in the comments: give me real, honest feedback. I’m sure current approach/version has tons of issues. I want to turn this into the best learning tool in the world and, eventually the go-to place for learning and career development, so any feedback is really helpfulGitHub repo: https://github.com/zoonk/zoonk
