Complete digital intelligence across thousands of platforms. Trusted by professional investigators.
100% local. 100% free. Verifiable by anyone.
A browser extension that captures web pages as evidence, not screenshots — sealed, timestamped, filed into cases, and verifiable by anyone, offline. Everything runs inside your browser, on your machine — your evidence never touches a cloud.
No cloud, no account, no telemetry — everything runs on your machine
SHA-256 fingerprints and a tamper-evident seal, the moment you capture
Evidence filed into cases beside a permanent, hash-chained notebook
Every export ships its own verifier — no internet, no install, any machine
There are no tiers to compare, so here is the whole column of ticks. Tools like this usually cost hundreds of dollars a year — Forensic Capture ships the full toolkit to everyone.
The only plan there is
Part of the UserSearch toolkit — free because investigators shouldn’t have to pay to keep their own evidence intact.
A screenshot is a picture. A Forensic Capture is a sealed record — here is what happens in the second after you click.
Full page, region, element or screen recording — stored as the image, the page snapshot and the raw server response.
Every artifact gets its own SHA-256 fingerprint, computed on your machine the moment the evidence is captured.
The fingerprints combine into one master fingerprint, signed by your installation — a tamper-evident seal on exactly what was captured.
An anonymous fingerprint — never the evidence — goes to two independent timestamp services (RFC 3161 + OpenTimestamps), showing the evidence existed no later than the anchor time.
A SHA-256 fingerprint is a short code calculated from a file’s exact contents — like a fingerprint for data. Change even one pixel and it comes out completely different, and no computer on earth is known to be able to fabricate a different file with a matching fingerprint. Verification simply redoes the math and compares: the same fingerprint means the file is bit-for-bit unchanged since capture — checkable by anyone, offline, on any machine, with the verifier shipped inside every export.
Every capture lands in a case — tags, subjects, a chain-of-custody timeline, and a notebook rebuilt for the web era.
Entries are timestamped, operator-attributed and hash-chained — never editable or deletable. Corrections are appended, like a paper notebook.
Evidence archives but never deletes or moves between cases — the record you show later is the record you built at the time.
One PDF: every capture with its fingerprints and timestamps, linked notes, exhibits and the full timeline — strictly factual, designed for evidential use.
One passphrase-encrypted file. When a colleague opens it, their copy re-verifies every item against its seals on arrival.
Opened case. Subject profile URL received from client intake.
Captured subject profile page — listing shows item as “new / boxed”.
Seller responded in chat. Captured conversation overlay.
Correction to 09:41 — intake email arrived 09:38, not 09:40. (Appended; originals are never edited.)
Forensic Capture is a browser extension — it runs entirely on your device, not in a cloud. Your captured evidence never leaves your machine — only anonymous cryptographic hashes go to timestamp authorities. That isn’t a promise buried in a policy: the extension keeps a local network activity log of every request it has ever dispatched, so you can audit it yourself.
Even text recognition and video processing are bundled inside the extension — nothing ever loads from the internet.
Yes — completely. No tiers, no capture caps, no scroll limits, no subscriptions, no license keys, and no account needed. Forensic Capture is part of the UserSearch toolkit, and the full feature set is free for everyone.
UserSearch Forensic Capture is on its way to the Chrome, Edge and Firefox stores. A free extension that runs entirely in your browser — never in a cloud — and produces evidence anyone can verify. This page links straight to the stores the moment they go live.
