From confident statement to source-linked receipt.

A phone connects a receipt, a redacted document, and a photograph into one evidence-review path.

The Truth Calculator helps you make one claim specific, preserve the records connected to it, see the unresolved gap, and choose a safer next step.

1. Capture one consequential claim. State exactly what you may rely on.

2. Preserve the receipts. Keep the source, origin, date, and reviewed passage connected.

3. Connect claim to source. Show support, conflict, and unresolved states.

4. See the evidence gap. Keep the missing receipt visible.

5. Choose the next step. Preserve, verify, seek human review, prepare a private packet, or do not rely yet.

Integrity is useful—but it is not truth. A cryptographic file hash can help identify whether the same bytes were compared. It does not prove authenticity, authorship, completeness, or truth.
