Start keeping a record before your next piece

General information, not legal advice.

A record made at the time, and anchored with OpenTimestamps, shows that the files existed by the time of the stamp. The clock of your own device alone is not independent.

What to do

  1. Keep working files, not only exports: save drafts and intermediate versions under their own names as you go.
  2. Use the tools' own history where it exists (version history in documents, history panels in drawing apps).
  3. Add each saved version to the recorder. It computes a fingerprint (SHA-256) of the file in your browser and appends it to a log on your device. The file itself is never uploaded.
  4. Now and then, export the log and have its fingerprint stamped by OpenTimestamps, a public timestamping service. The recorder page explains the steps.
What this gives you: a record that these files existed at these times. What it does not give you: proof that no AI was used, or that anyone will accept it. Retyping generated text produces the same kind of record.
