Hi Product Hunt! I’m Andrii, and I built Watt. I built Watt because I love learning unexpected things, but useful facts are scattered across the internet and vary in quality. Watt brings them together with sources and turns each one into a small learning loop: a fact, a clear explanation, audio you can listen to, and a quiz. You can browse by topic and choose a child, adult, or expert explanation. Watt currently has around 1,500 facts, and I’m working toward 5,000, with more languages and voice options on the roadmap. The hardest part has been connecting research, writing, audio, quizzes, and publishing into a reliable system that can keep improving the product. I’ve also learned from early testers that discovery is only the beginning: people need a reason to come back, so I’ve been building progress and game-like features around the facts. I’d love for you to try a fact and tell me where the experience feels useful, confusing, or worth returning to. What would make Watt part of your learning routine?
