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, preserved entirely on your own machine. UserSearch Forensic Capture saves web pages and social media posts as tamper-evident records for online investigations and OSINT. Full-page screenshots, screen recordings and page-source snapshots are each SHA-256 hashed, sealed and independently timestamped the moment you save them. Everything runs locally. Your files never leave your device: no cloud, no telemetry, no analytics. Free and unlimited. ━━━━━━━━━━━━━━━━━━━━ 🕵️ INVESTIGATION FEATURES ━━━━━━━━━━━━━━━━━━━━ 📱 SOCIAL MEDIA AS IT REALLY LOOKS — dedicated handlers for the major social platforms, with one click to expand comment threads and reply chains first. 🤖 AI CONVERSATIONS — preserve full chats from popular AI assistants as sealed, dated exhibits. 🔗 CONNECT THE DOTS — usernames, emails and phone numbers are extracted automatically, and you're flagged when the same identifier turns up in different items. Subject links are suggested automatically for you to confirm. 📍 SUBJECTS — pin photo GPS to a subject and build searchable dossiers, exportable as a single PDF. 🎥 DYNAMIC CONTENT — screen-record any page as it plays, with audio, hashed and sealed like every other exhibit. 🔎 SEARCHABLE SCREENSHOTS — on-device OCR makes every image full-text searchable. 👁️ CHANGE MONITORING — watch a URL and automatically save a new copy the moment the page changes. ━━━━━━━━━━━━━━━━━━━━ 📸 FAST, COMPLETE PAGE SAVING ━━━━━━━━━━━━━━━━━━━━ - Full-page screenshots of unlimited length (scroll-stitch); handles infinite scroll and lazy loading - Visible area, any element, a drag-selected region or the comments section in one click - Every mode available from the right-click menu or a keyboard shortcut - Runs in the background and resumes after interruptions - Dismisses cookie and consent banners automatically - Self-contained DOM snapshot, single-file MHTML archive and raw HTTP response - Cookies, tokens and credentials redacted automatically - Full URL and redirect-chain provenance; HiDPI/retina-aware - Branded footer stamp with time, URL and operator ━━━━━━━━━━━━━━━━━━━━ 🔐 INTEGRITY ━━━━━━━━━━━━━━━━━━━━ - SHA-256 on every file, with streaming hashing for large videos - Tamper-evident Merkle manifest, Ed25519 seal per install and append-only audit log - RFC 3161 trusted timestamps (bring your own authority), corroborated on the Bitcoin blockchain via OpenTimestamps - Machine-clock integrity check; write-once, immutable records - Operator identity stamped on every item ━━━━━━━━━━━━━━━━━━━━ ✅ ANYONE CAN CHECK IT — OFFLINE ━━━━━━━━━━━━━━━━━━━━ - One-click integrity check with a plain PASS / FAIL - Offline fixity and signature checks — no internet or extension needed - Drag-a-folder verifier included in every bundle - Trusted time proofs checkable against public infrastructure ━━━━━━━━━━━━━━━━━━━━ 📁 CASES & CHAIN OF CUSTODY ━━━━━━━━━━━━━━━━━━━━ - Everything filed under a case, stored on your device - Per-case timeline and chain-of-custody view - Append-only contemporaneous notes with time and date; corrections keep the original - Subject dossiers, tags and bulk tagging - Encrypted, passphrase-protected backup, restore and sharing - Full-text search across everything - Blocklist domains, usernames and URLs (regex or exact match) ━━━━━━━━━━━━━━━━━━━━ 📑 REPORTS & EXPORT ━━━━━━━━━━━━━━━━━━━━ - One-click PDF and Word (.docx) reports, generated on your device - Whole-case report in one click - Portable, self-verifying BagIt bundles - Annotate with boxes, arrows and highlights; burn-in redaction leaves the original untouched - CSV export of extracted comments and identifiers ━━━━━━━━━━━━━━━━━━━━ 🛡️ PRIVACY & ACCESSIBILITY ━━━━━━━━━━━━━━━━━━━━ - The only data that leaves your device: opaque sign-in tokens and, if you enable it, anonymous hashes sent to independent time-stamping authorities. A hash reveals nothing about the page. - Inspect the network-activity log yourself — a single, build-enforced egress point - No cookie access, ever - Least-privilege permissions, requested in context with a plain-language reason - Keyboard, screen-reader and reduced-motion support ━━━━━━━━━━━━━━━━━━━━ ACCOUNT ━━━━━━━━━━━━━━━━━━━━ A free UserSearch account is required — just a verified email. No name, card or payment. Sign-in exchanges only opaque tokens; your files and case data never touch the account. When signed out, you can still view, verify and export work already on your machine. Free forever — no tiers, no locked features. Published by UserSearch.com for the OSINT community.
