About

Reality Check generates cryptographic receipts that prove a digital artifact existed at a specific time and has not been altered since.

You can create receipts for:

Files

Text

URLs

All hashing and receipt generation happens locally in your browser. No data is sent to external servers.

Each receipt includes:

SHA-256 hash

Timestamp

Artifact metadata

Explicit non-claims

What it proves:

That a specific hash existed at a specific time

That the artifact has not changed since the receipt was created

What it does not prove:

That the content is true or accurate

Who created or authored the artifact

The meaning or intent of the content

Version 0 stores receipts locally and does not integrate with external timestamp authorities.
