Webinvestigator

WebInvestigator is a professional evidence capture and case management tool for investigators, intelligence analysts, legal professionals, and OSINT researchers. Built for anyone who needs to prove something happened online.
Courts reject plain screenshots every day — no timestamp, no source verification, no proof of integrity. WebInvestigator captures web evidence with automatic SHA-256 cryptographic hashing, chain of custody metadata, and full URL and device stamping from the moment of capture. Everything stays on your device. Nothing leaves your machine.
