Papiers.ai: free workspace for everything you read — helps you make sense of info overload when your attention can't keep up
It's a web workspace for reading and research — open it in your browser, no install, and start making sense of what you read. The idea is sharp: AI is producing more worth reading than ever, but your time and attention aren't growing to match, so the software should do the heavy lifting. It just hit Show HN, so it's early — a great moment to try it and see where it's headed. If your tabs and saved papers are a graveyard, this is built for exactly that mess. 📚
🎯 More to read than ever, same 24 hours — a workspace that helps you process it beats 40 open tabs every time.
