The point that may matter later.

Add proof where it matters.

Create a verifiable fingerprint for an important file, AI conversation or record. Keep the proof in the way that fits, then check it later.

Ways to ProofStamp

Start with what you need to preserve.

ProofStamp a file

Create verifiable evidence for a photo, document or other important file.

ProofStamp an AI conversation

Keep a portable, verifiable record of an important AI session.

Make it publicly verifiable

Anchor a fingerprint publicly when independent timestamp evidence matters.

How it works

Make the record verifiable before you need it.

Record

Start with the exact file, conversation or record.

ProofStamp

Create its fingerprint and preserve the evidence.

Check later

Recreate the fingerprint and compare.

What it proves

Useful proof has clear limits.

It can help show

  • A file or record checked later matches an earlier recorded fingerprint.
  • A dated receipt can support chronology.
  • A public timestamp can show a fingerprint existed no later than its recorded time.

It does not prove

  • That the content itself is true.
  • Who originally created it.
  • When the original content was first created.

Add proof to a workflow without replacing the workflow.

For approvals, inspections, handoffs, AI-assisted work and records that may matter later.
