Capture the Web as Evidence

To create new captures, yes — a free UserSearch account (just a verified email; no name, no payment). It only exists to confirm you have a valid account: the sign-in exchanges anonymous tokens and never carries your evidence, page content or email, and your evidence is never tied to it. Evidence you have already captured stays fully usable without signing in — you can view, verify and export it in read-only mode.

Right now for Chrome and Edge — install it from the Chrome Web Store using the Download button on this page. Safari and Firefox support are on the way, and this page will link their stores the moment the listings are live.

No. Your captured evidence never leaves your machine — only anonymous cryptographic hashes go to timestamp authorities, and only if timestamping is enabled. No cloud storage, no telemetry. Signing in to capture exchanges only opaque account tokens — never your evidence, page content or email. A local network activity log records every request the extension has ever made, so you can audit it yourself.

A screenshot is a loose picture with no history. A Forensic Capture is a sealed record: multiple fingerprinted artifacts, a signed master fingerprint, optional third-party timestamp verification, a case file and notebook behind it, and an export anyone can verify offline.

Yes, on your terms. One-click focused presets grab just the part that matters — like the comments — on supported sites. On-page tools can dismiss a cookie or consent banner (using the banner’s own neutral control, never “reject all”) and expand comments and threads so hidden replies are on the record — you choose which. Nothing happens automatically: every action is something you trigger, each one is written into that capture’s audit trail, and a one-click “reset page” undoes it all.

A fingerprint match shows a file is bit-for-bit unchanged since capture — the record is tamper-evident, meaning any alteration becomes visible. Seals and signatures show the record is intact; who captured it is attributed by the declared operator identity stamped on every capture.

That the evidence existed no later than the anchor time. An anonymous fingerprint — never the evidence itself — is anchored two independent ways: an RFC 3161 timestamp authority and OpenTimestamps (anchored in Bitcoin). The anchor policy is chosen per case at creation and locked once chosen.

Forensic Capture is designed for evidential use: it produces a factual, verifiable record with strictly factual reports — no certifications or legal claims — usable in any jurisdiction. How a specific item may be used in a given proceeding is always a question for your counsel and the venue; what the tool gives you is a record anyone can verify, offline, on any machine.

No. The interface is plain-language throughout: every technical term has a “?” explainer, there is a built-in glossary, and guided tours walk you through the popup and the Evidence panel. Students and first-time investigators are a core audience.

Chrome and Edge get the full experience, including the side-panel Evidence workspace. Firefox runs the same core, with the Evidence panel in the browser sidebar and video via the browser’s screen-share picker. Saving the original media a page plays ships on Edge and Firefox. Everything — including text recognition and video processing — is bundled inside the extension, so nothing loads from the internet.
