Show HN: Open-source alternative to Duolingo for learning anything

https://www.zoonk.com/
6•ceolin•12h ago
I built an open-source tool for learning anything using AI:

- Type what you want to learn - It creates a full interactive course for you

Move from beginner to mastery of any subject, even complex things like Quantum Physics

It 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 skills

It's more hands-on than reading a long textbook or watching a video

Plus, 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/uni

Of 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 ways

If 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 helpful
