PageWitness preserves public web pages, social-media posts and videos as digital evidence. Paste an address: an isolated browser captures the page with everything the server sent (a whole-page screenshot, the network archive, media and a PDF), every file is fingerprinted with SHA-256 and locked in WORM storage, and the evidence pack is signed with Ed25519 and timestamped by two independent RFC 3161 authorities. Anyone can verify a pack offline with the open verifier, without trusting us. Packs include a PDF report in Hebrew or English and a chain-of-custody report. Built for lawyers, investigators, compliance and trust-and-safety teams who need to show what a page or post said at a given time. PageWitness proves integrity and provenance; it does not prove the content is true, and admissibility is for the court to decide.
