Evidence

Build an evidence pack before you need one.

Organize ownership records, source material, and local file fingerprints into a portable manifest. Your selected files are processed only in this browser.

About 10 minutes Proof manifest in Markdown + JSON Private in this browser

Gather

Put source files and ownership records in one controlled folder.

Fingerprint

Create a SHA-256 identifier for each selected file without uploading it.

Save

Download a readable manifest and keep it beside the source files.

Honest limit: a fingerprint identifies the exact bytes you selected. It is not a copyright registration, trusted timestamp, or proof that you created the work.

4. Download the manifest
