Real cameras can lie now. Witness proves yours didn't.
Every photo and video you take in Witness is sealed the moment you capture it: a tamper-evident fingerprint, a Secure Enclave signature, Apple device attestation, and a Bitcoin timestamp. Anyone can check it later, and no account is needed to verify.
WHAT YOU CAN DO
• Capture verified photos and videos in seconds
• Share a proof link anyone can open and check
• Publish a capture to the public Witness map, so people can see what happened and where
• Turn on Public Mode to auto-publish as you shoot
• Sign in with Apple in one tap. No username, no password.
WHY IT MATTERS
Anyone can fake a photo now. Witness gives you a way to prove a real one is real, from the moment of capture to the place it is shown. Built for journalists, creators, and anyone who needs their word backed by proof.
