Hey Product Hunt 👋 I'm Sami, and I built Curio. I built it for one feeling: being the person in the room who actually gets it. Knowing why a 1% fee can quietly eat a quarter of your savings. Why coffee doesn't really give you energy. Why a pill that "halves your risk" might barely change it. Small ideas that make everyday decisions easier and conversations more fun. The catch: we read this stuff and forget it by Friday. Reading more wasn't the fix. Remembering was. So Curio does two things: 1. One idea a day, taught in a few minutes with visual cards and questions that make you think. 2. It brings each idea back right before you'd forget it (FSRS spaced repetition), with a new question every time, until it's locked in. Gand-written ideas across 16 topics, from money and health to space and persuasion. Free, no ads, no account, works offline. Curio Plus is optional: three ideas a day plus Ask Curio. I'd love your honest take: which topic should I write next, and did your first lesson make you want a second one? Sami
