Upload any file — a contract, a photo, a report. Get a tamper-proof certificate proving exactly when it existed. Permanently recorded. Verifiable by anyone.
Inventory fraud and unverifiable documentation prevent supply chain assets from being used as bankable collateral. Regional banks cannot lend against what they cannot verify.
AI agents generate contracts, decisions, and critical outputs with no record of what was produced, when, or by whom. The emerging AI economy has no accountability layer.
Your document never leaves your device. We compute a unique fingerprint locally and record it permanently — so you hold the original and we hold the proof.
Uncompromising privacy: The original file never leaves your device. Anyone can verify the certificate — only you hold the document.

Every AI proposal, contract, or high-stakes output gets a permanent, human-readable audit trail — attached at the moment it is created.
A contract, a compliance report, an approval — any output that needs to be trusted.
Via the web app, API, or AI agent integration — no manual steps required.
The document's unique ID is generated on the client. The file itself is never transmitted.
The fingerprint is anchored to an immutable, publicly auditable ledger. Timestamp is locked forever.
A human-readable PDF certificate with QR code is returned. Anyone can verify it, anytime.
Deployed locally with strict data residency. Every certificate is permanently verifiable — from the warehouse floor to the boardroom.
Eliminate ghost deliveries with point-of-scan document timestamping. Every delivery note, every invoice — cryptographically proven at the moment it happens.
