DocProof
Prove your document existed before you shared it
Prove a document existed at a specific moment. SHA-256 fingerprint + UTC timestamp + PDF certificate. No account, no file storage. $9 one-time.
Hey Product Hunt! I built DocProof after a frustrating experience where I had no way to prove a pitch deck existed before a meeting.
The idea is simple: upload any file, get a SHA-256 fingerprint computed in memory, a UTC timestamp, and a PDF certificate. Your file is never stored. The proof is permanent and publicly verifiable by anyone, no account needed.
$9 one-time per proof. Pro plan at $12/month includes 5 proofs. REST API available for developers who want to integrate it.
Would love to hear your feedback and use cases. What documents do you wish you had timestamped in the past?
