How it works
OSINT (open-source intelligence) is finding information from publicly available sources. This tool is a pivot dashboard: you give it one starting clue and it hands you a fan of links to check across many sites at once.
It builds links — it doesn't fetch them
Every platform has a predictable URL for a profile (github.com/<user>, reddit.com/user/<user>). The tool slots your input into ~60 known patterns and shows them as links. You click to confirm which actually exist.
Why it can't auto-verify
Browsers block a page from silently loading another site and reading the result (a security rule called CORS). Auto-checking needs a backend server — which would break the "nothing leaves your browser" promise. So this stays a link builder.
The Gravatar trick
Gravatar finds an avatar from a hash of an email, never the email itself. The hash is computed locally in your browser via the Web Crypto API (SHA-256), so even that keeps the raw email private.
