# ProofSnap Discussions

ProofSnap turns a web page into a sealed evidence package that anyone can verify. It is built for lawyers, investigators, OSINT analysts, journalists and compliance teams who need to show what a page displayed and when. It works as a browser extension for Chrome and Edge and as a server-side REST API with a web dashboard. The extension captures the page you are looking at, including content behind a login: full-page screenshot, HTML and text, metadata (URL, NTP-verified time, DNS, WHOIS, HTTP headers), an evidence PDF, a forensic log and a chain of custody record aligned with ISO/IEC 27037. It has dedicated capture for WhatsApp Web, Telegram, Discord, Slack, Messenger and LinkedIn, plus video recording, multi-tab sessions and certification of local files. With the API, captures run on ProofSnap servers in the EU, independent of the person who requests them. Schedule captures, receive webhooks, organise them into matters, place them on legal hold and download packages from the dashboard. Every file is hashed with SHA-256 and listed in a manifest signed with an RSA-4096 key. Depending on plan, the manifest is anchored to Bitcoin via OpenTimestamps and can carry an eIDAS qualified electronic timestamp from Disig a.s., a Qualified Trust Service Provider on the EU Trusted List. Packages can include a pre-filled FRE 902(13)/(14) declaration template for US filings. Anyone can verify a package without ProofSnap, using the bundled scripts, the free web Trust Verifier or the MIT-licensed command-line verifier. The evidence PDF is available in 29 languages. Subscriptions start at 8.99 USD per month with a 7-day trial, and pay-per-use packs are available.
