Guide
Protect, timestamp and verify — without the complexity
Start with what you want to do. The Guide connects every HashMyWords workflow and explains the proof underneath it.
What do you want to do?
Choose the task that matches what you are trying to protect or prove. You can move into the deeper technical guides afterwards.
Harden and timestamp a reference copy before uploading it to ChatGPT, Claude, Gemini, Microsoft Copilot or another AI tool.
Read the workflow → TimestampTimestamp a fileLearn how file proofs work, what stays on your device, what SHA-256 is public, and how to verify the exact file later.
Read the file guide → TimestampTimestamp textUnderstand public and private text proofs, then create a timestamp for the exact words you want to preserve.
Read the text guide → VerifyVerify an existing proofUnderstand secret-code verification and exact-file verification before checking a saved proof.
