Hi Product Hunt! I'm Duy, the engineer on Concept Dangle. Yen (Ngô Hải Yến) is the founder, and I'm posting for both of us. Concept Dangle is for anyone learning anything: a uni course, a new programming framework, a research paper, a language. The problem is always the same. You hit a paragraph that quietly assumes five things you don't know, and you can't tell which one to learn first. Paste the text in, and Concept Dangle picks out the concepts it takes for granted and lays them out as a concept graph. Mark each one Unknown, Learning or Mastered, expand any of them to find their own prerequisites, and share the graph with someone you're learning with. It works in English and Vietnamese, and you can try it without signing up. It's early and there are rough edges. The AI only picks concepts that actually appear in your text, so it won't invent things, but it can miss prerequisites the text never names. We'd love you to try it with something you're reading today and tell us where it gets it wrong.
