OSINT—short for Open Source Intelligence—is basically finding cool info from stuff anyone can access online. It’s like digital detective work, minus the trench coat. Journalists use it to check facts, security experts track threats with it, and curious folks use it to dig up surprising stories hiding in plain sight.
All you need is your browser. You poke around websites, peek at metadata, chase down digital crumbs—and you don’t need to be a hacker. Just sharp eyes and some solid logic.
Each puzzle is just a single file that runs right in your browser. No accounts, no logins, no servers. Just open it, start exploring, and follow the clues—just like a real OSINT pro would.
Because everything stays on your device, it’s great for class demos, hacker workshops, or just leveling up your skills in private.
When you solve a puzzle, you get a PDF certificate on the spot—name, date, title, boom.
And don’t worry, your data never leaves your browser. We use JavaScript to generate everything right on your machine. Private and safe.
