Prove Your Documents Existed
Timekeeper creates a tamper-proof timestamp for any file — a contract, photo, idea, or report — so you can prove it existed at a specific moment in time.
Upload Any File
Upload a PDF, image, Word document, or any other file. We generate a unique fingerprint of its contents.
Sealed in a Secure Record
Your file's fingerprint is recorded on a tamper-proof ledger with an exact timestamp — like a digital notary.
Verify Anytime
Anyone can upload the original file to confirm it's genuine and unchanged — no account needed to verify.
