Verify a document
Check a document against AXO's public record. Everything is computed in your browser: the file is fingerprinted here and never uploaded. Verification is free.
Check the document in front of you
You arrived from a certificate's QR code, which only points to a record. The record cannot tell you whether the paper or file you are holding is the sealed one. Pick that file (or its digital copy): it is fingerprinted on this device and compared with the sealed fingerprint below.
Look up a fingerprint or a file
Paste a document fingerprint (64 characters), or pick the file and it is fingerprinted here.
Check a certificate file
Drop a certificate file you downloaded. This page recomputes it from the file alone: the sealed entry, its path to the day's record, the signatures, and the on-chain anchor read from the public chain. AXO's stamp records are not used for the verdict.
A stamp proves a file existed in this exact form by its seal day. It does not say the contents are true or legally binding.
