DocProof
Cryptographic timestamps for documents — no file storage
DocProof proves a document existed at a specific moment — without storing the file. Upload any file → SHA-256 fingerprint computed in memory → file discarded immediately. You get a UTC timestamp, a Proof ID, a shareable verification link, and a PDF certificate. Perfect for founders, freelancers, and developers who need to prove ownership before sharing. $9 one-time per proof — no subscription, no account required.
I built DocProof after realizing there was no simple, privacy-first way to timestamp a document. Existing solutions either stored your files (privacy risk) or required blockchain (overkill).
DocProof just hashes your file in memory, timestamps it, and gives you a PDF certificate — the file is never stored. $9 one-time, no account needed.
Would love your feedback, especially on use cases I might have missed!
