How to use this directory
Start broad, then narrow. Begin with General Search and Google Dorks to see what is publicly indexed, then move to the specialised categories (Username, Email, Phone, Image) as you find identifiers. Record every source as you go — the Web Archives tools let you preserve pages that might disappear.
Verify with two independent sources. Reverse image search hits, geolocation guesses and people-search records are leads, not facts. Confirm each finding with a second, unrelated tool before you rely on it.
Stay lawful and ethical. These tools only access publicly available information. Do not use them to harass, stalk or access accounts you do not own. Investigations involving specific individuals should have a lawful basis and, where required, written authorisation.
