A cryptographic seal on every document, and open verification for anyone who needs to check it.
Start free → See all capabilitiesArguments about documents are usually arguments about versions: which copy is the real one, and whether a figure or a clause was changed after the fact.
FINIS seals every document with a cryptographic fingerprint on arrival. Anyone can verify a document against its seal and get a definitive answer — without a FINIS account.
Automatically, when it enters FINIS.
The seal travels with the document.
The check returns authentic, or not a match.
Every FINIS document carries a cryptographic seal — a fingerprint that changes if a single byte does.
Verification confirms a document against its seal — and tells you plainly whether it matches.
The recipient reads and signs in the same place — and a decline is recorded just as carefully as a signature.
No. Verification is open.
Any change to the document's content breaks the seal.
