docuProof — Blockchain-Anchored Proof

Your file's alibi. Timestamped proof of any file, forever.

What it does

When someone claims your photo is AI-generated or your contract was edited — how do you prove them wrong? With docuProof. In 60 seconds, docuProof creates a unique hash of your file and permanently anchors it to the blockchain. That timestamp can never be faked, altered, backdated, or destroyed — not by us, not by anyone. Your file never leaves your device. Only the hash is recorded. Proof lives forever. $2.89. Code PRODUCTHUNT for one free.
