Photo Authenticity,
Verified on the Blockchain

Notchd lets you prove a photo is real, unedited, and yours — the moment you take it.

How It Works

Every photo captured with Notchd is fingerprinted using SHA-256 hashing and optionally registered on the Polygon blockchain, creating a permanent, tamper-proof record of authenticity. No one can alter the photo after the fact and claim it's the original.

  • fingerprintGenerate a cryptographic hash of your image
  • linkRegister that hash on-chain (Polygon) for immutable proof
  • grid_viewBrowse your feed and search verified photos
  • lockSign in securely via email link, Google, or Apple

Why It Matters

In a world of AI-generated and doctored images, Notchd gives photographers, journalists, and creators a verifiable chain of custody for their work — from the moment the shutter fires to forever.
