If you've ever looked at a photo or video and wondered, is this real or was it generated by AI? This is for you. Meet Witness by Real Human. Here's why this is awesome. When you snap a photo or record a video using Witness, it's instantly cryptographically signed right inside the app. That means proof of authenticity is embedded directly into the file itself. No cloud uploads, no ads, no tracking, just real verifiable content. Each capture is linked to your unique Witness ID, basically a digital fingerprint that proves you created it and anyone can verify it. If someone tampers with the file, verification fails instantly. That's huge. This is perfect for anyone who values privacy, truth, and being represented accurately online, whether you're sharing memories, documenting events, or protecting your work. And the best part, it's ridiculously easy. Capture, sign, validate. So if you want to take control of your digital content and make sure what you share is undeniably real, download Witness on Android or iOS today. Let's make authenticity the new standard.

Why this matters

  • AI-generated media makes “real” hard to prove.
  • Identity alone does not prove when media was created.
  • Provenance without capture integrity is incomplete.
Core promise
Prove this exact media is authentic at capture — and optionally prove who captured it.
Privacy stance
Anonymous by default. Identity is opt-in and scoped.

How Witness works

1) Capture
Create photo or video in the Witness app.
2) Sign at capture
Media is cryptographically signed immediately.
3) Optional attestations Attach identity only when appropriate.
4) Verify anywhere Independent tools validate integrity and disclosure.
Trust model: Trust the math, not the platform.

In one sentence

Witness proves that this media is authentic at capture, and allows identity to be attached only when and where it makes sense.
