Process
From URL to verifiable record
-
01
Paste a URL
Any public page. We load it in Chromium and wait for the rendered DOM — not the first byte off the wire.
-
02
We seal the artifacts
Rendered HTML, full-page screenshot, Markdown extract, and response headers — each with its own SHA-256.
-
03
Anyone can verify
Hashes sit on the capture page. Recompute them in this browser, or offline from the downloaded files.
Use it when
A page “never said that.”
Counsel, reporters, and brand teams keep a timestamped record that a third party can hash themselves. We are not a notary.
