Most OSINT tools are great at one thing. You run holehe for emails, sherlock for usernames, sublist3r for domains. But you're the one deciding the workflow, switching between tools, copy-pasting results.

I wanted to remove that middle layer. So I built OpenOSINT — you describe a target in plain English, the AI figures out what to investigate and how, runs the tools, and hands you a report.

How it works

The core idea is simple: instead of hardcoding a fixed pipeline, I use Claude's native tool use API to let the model decide at each step what to do next based on what it found so far.
