Hi Product Hunt, I'm Wojtek, the solo maker of Cosminds. I read a lot. Or I told myself I did. The honest version: I'd finish a book, feel smart for a week, then forget almost everything. Not the general idea, the specific arguments, the facts, the lines I underlined because they mattered to me. I spent a year on books about addiction and behavioral science, Never Enough, Predictably Irrational, Sapiens, and when someone challenged me on it, I had nothing. I knew I'd known it once. That was all. That's the problem. You read a lot and it scatters by source: this book, that video, a dozen articles. One idea ends up in twenty places and you never find it again. Cosminds organizes what you read and watch by idea, not by source, and then makes you remember it: • Feed it books, PDFs, YouTube, articles, your own notes. It pulls out the specific claims and groups every source that touched one idea together. • It drills you until you can write the idea back from memory, and an AI coach grades the meaning, not the exact words. • Its AI Wiki answers only from your own library, with the source cited. When you haven't read about something, it says so instead of guessing from the internet. I started building it in February this year, for myself. Five months later it's live. The thing I got clearer on the whole way through: a summary from the internet misses the point. What you want back is your own highlights and notes, the things that were important to you, not a generic AI answer. Who it's for: people who read or watch a lot and are tired of forgetting it. It's early and I'm solo, so I'd rather hear what's broken than what's polished. Free to start, no card. For Product Hunt, the code PRODUCTHUNT takes 50% off Pro or Scholar for 3 months. What I'd love to know: what's the first thing you'd forge, and where does it break for you? Wojtek
