How it works.

SaveProof records a Document Fingerprint and signed time without storing your original content or composition.

01

Build a composition

Add one text note, one or more files, or both. Your browser fingerprints every item and the complete ordered composition.

02

Create Proof

SaveProof receives only the Document Fingerprint, records the time, signs the canonical Proof, and returns a Verification ID.

03

Keep and verify the Certificate

The Certificate carries the signed composition and recorded text. Use Verify later to check it and match original files locally.
