Hey Product Hunt! 👋 I'm a frontend developer with 5+ years of experience — and I kept forgetting things I already knew. Not complex stuff. Basic things. How localStorage differs from sessionStorage. Useful JS methods I'd learned once and then lost. Patterns I'd used on a project six months ago and couldn't quite recall. I'd look them up, understand them again, and forget them again two weeks later. I tried writing notes. I tried bookmarks. Nothing stuck. I knew about spaced repetition — the science is solid. Hermann Ebbinghaus proved in 1885 that we forget 70% of new information within 24 hours, but reviewing at the right intervals locks it in permanently. The problem was every tool I looked at felt like it was built for medical students memorizing anatomy. Heavy, complicated, desktop-only. I just wanted something simple I could open in a browser, add a card, and move on. So I built study-lingo for myself. One month of evenings and weekends. The idea was simple: a clean web app powered by the SM-2 algorithm (same science as Anki), but with a modern interface that doesn't get in the way. You add a card, study it, rate how well you remembered it, and the app figures out when to show it to you again. No installs, no configuration, no friction. Somewhere along the way I realised other developers — and students, and anyone who wants to keep their mind sharp — probably have the same problem. So I kept going: rich text answers, hierarchical topics to organise knowledge the way your brain actually works, study analytics so you can see your streak and progress, and a full session flow with keyboard shortcuts. It's still early. But it works — I use it myself every day. If you've ever re-learned the same thing twice and wished you hadn't, I built this for you. Would love to hear what you'd actually use it for.
