ProofSnap
ChatGPT pluginWeb pages as signed evidence
ProofSnap captures a public web page as an evidence package: screenshot, HTML, page text, network metadata, SHA-256 hashes, a signed manifest, chain of custody, an OpenTimestamps Bitcoin proof and, on request, an eIDAS qualified timestamp.
In ChatGPT you can capture a page, compare it with an earlier capture and see what changed, watch a page on a schedule, organize captures into matters, verify your stored captures and check a manifest hash in ProofSnap's public ledger. Each finished capture comes with a download link and its manifest hash.
Intended for lawyers, compliance teams, journalists, investigators and anyone who needs to show later what a web page displayed. Sign in with a ProofSnap account.
