Forensic Web Capture: Court-Grade Evidence for OSINT | UserSearch

Forensic capture of social media, chats & any web page. Sealed, timestamped, 100% local & free. Built for OSINT & investigators.

🔒 Court-grade web evidence, captured entirely on your own machine. UserSearch Forensic Capture is a forensic web capture tool for online investigations. Capture and preserve any website or social media page as tamper-evident digital evidence — full-page screenshots, screen recordings, and page-source snapshots, each SHA-256 hashed, sealed, and independently timestamped the instant you capture. Built for OSINT investigators, fraud examiners, journalists, trust & safety teams, lawyers, and law enforcement who need web evidence that holds up in court. Everything runs locally — your captures never leave your device. No cloud, no telemetry, no analytics. Free and unlimited, on Chrome, Edge & Firefox. ━━━━━━━━━━━━━━━━━━━━ 🕵️ BUILT FOR INVESTIGATIONS ━━━━━━━━━━━━━━━━━━━━ 📱 CAPTURE SOCIAL MEDIA AS IT REALLY LOOKS — dedicated handlers for Facebook, Instagram, X, YouTube & TikTok, with one click to expand comment threads and reply chains before you capture. 🤖 PRESERVE AI CONVERSATIONS — capture full ChatGPT, Claude & Gemini chats as sealed, timestamped evidence. 🔗 CONNECT THE DOTS — automatically extract usernames, emails & phone numbers, and get flagged when the same identifier turns up across different captures. Auto-suggested subject links you confirm. 📍 SUBJECTS — pin photo GPS to a subject and build searchable subject dossiers, exportable as a single PDF. 🎥 RECORD DYNAMIC CONTENT — screen-record any page as it plays, with audio, sealed and hashed like every other exhibit. 🔎 SEARCH YOUR EVIDENCE — on-device OCR makes every screenshot full-text searchable. 👁️ WATCH FOR CHANGES — monitor a URL and auto-capture the moment the page changes. ━━━━━━━━━━━━━━━━━━━━ WHY IT'S DIFFERENT ━━━━━━━━━━━━━━━━━━━━ 🔒 100% LOCAL — Captures, hashes, reports, and verification all happen on your device. The only things that ever leave are opaque tokens and, if you enable it, anonymous hashes to independent timestamp authorities. A hash reveals nothing about the page. ⚖️ COURT-GRADE, NOT SCREENSHOT-GRADE — SHA-256 on every artifact, a tamper-evident Merkle manifest, an Ed25519 seal per install, and RFC 3161 trusted timestamps corroborated on the Bitcoin blockchain via OpenTimestamps. 🛡️ PRIVACY-FIRST — Least-privilege permissions, requested only in context with a plain-language reason first.
