How it works

Three steps to permanent proof

01

Upload

Drop your file, paste text, or describe your idea. We compute a SHA-256 hash client-side — your content never leaves your device unencrypted.

02

Timestamp

We apply a trusted RFC 3161 timestamp and optionally anchor the hash to the Polygon blockchain, creating a permanent, independent record.

03

Prove

Download your certificate, share a public proof link, or generate a dispute evidence pack. Your timestamp is permanent and verifiable by anyone.

Your ideas deserve a timestamp.

Free to start. No crypto wallet needed.
