1. Upload or paste
Add a file or text and choose the source context for the proof record.
Proof Registry
Prove it existed first
Protect your idea, file, prompt, or document with a timestamped proof record. Receive a Proof ID and verify it later through a public proof page.
How It Works
Simple proof registration
The product keeps the flow simple while generating a verifiable SHA256 fingerprint and UTC timestamp.
2. Register proof
The system creates a SHA256 fingerprint, records the UTC timestamp, and issues a unique Proof ID.
3. Verify later
Use the Proof ID to open the verification page or download the certificate PDF.
