Would Love Feedback on an AI Study Tool I'm Building I’m a high school student currently building Vulty, an AI study tool that organizes and turns lecture notes and PDFs into interactive, editable note summaries, flashcards, quizzes, and even 1 to 15 minute audio podcasts. We’re starting early access testing before launch, and we would love feedback and beta testers. You can test Vulty out at https://vulty.org/ . If you'd like to access Pro or Premium mode for testing for free, DM me and I c

Dense reading shouldn’t stop your momentum. Highlight the passage that isn’t clicking. Strang turns it into a short visual explanation, right inside your browser. One complete video is free.

I got tired of juggling 5 different apps to learn a language, so I built one that does it all For the last while I was learning German using Memrise for vocab, Anki for flashcards, iTalki for speaking practice, Youtube for listening, a bit of Duolingo and a notebook to (badly) track actual progress.

Instead of asking "what should I learn next?", I built a tool that diagnoses your actual gaps and tells you One pattern I keep seeing here (and had myself): you're learning a field - say backend development or ML - and at some point you don't know what you don't know. You've done tutorials, watched videos, maybe built some projects. But you can't tell if you actually have real understanding or just surface-level familiarity. I built a free tool called Cascade AI that tries to solve this.

Most AI learning tools explain concepts for you through summaries, notes, quizzes, and flashcards. But recognising an answer is not the same as understanding it. That’s why I built ReExplain ( for the @OpenAI Build Week Hackathon. ReExplain flips the roles - the AI becomes the curious learner, and you become the teacher. You explain the material in your own words, while the AI listens, identifies gaps, and asks follow-up questions that challenge you to think deeper. Powered by GPT-5.6 Luna and built with Codex, ReExplain is now live on Product Hunt! If the idea resonates with you, I’d really appreciate your upvote and support 😄 🔗 Product Hunt Launch Link: Watch the demo, try it, and share your feedback! #ProductHunt #OpenAI #BuildWeek #AI #EdTech #Hackathon
