Early access. Upload any file. itexisted.app computes a SHA-256 hash and anchors it to the Bitcoin blockchain via OpenTimestamps. Within an hour you have a self-proving proof that this exact file existed at that moment, verifiable by anyone, without trusting us.
No account required. No file leaves your device. The proof is a small .ots file that works offline, works in court, and survives even if itexisted.app disappears.
Built on the same infrastructure that anchors 4,000+ production commits per day. One file, zero friction, independent proof.
