Paste a report, or drop the .json file. Verification runs entirely in this page: the signature is checked against the public key the report carries, using the browser's own WebCrypto. The report never leaves this page, and you do not need a Humanize AI account — or to trust us.
The document hash, the findings and the edit trail are exactly as they were when the report was signed. Change one character of the draft, or one number in the trail, and the check fails.
It does not prove authorship. The key is generated in the writer's browser, so a valid signature shows a consistent device and an unaltered record — evidence to weigh, not a verdict. Read the cadence figures alongside it.
