What Article 50 and SB 942 actually require.

Fifteen questions, about four minutes. It scores five areas — scope, disclosure, transparency, detection and evidence — and names the gaps a regulator, a distributor or an insurer would find first. Results appear immediately; the email is optional.

What it reads against

Two regimes, one set of artifacts.

The duties differ in wording and overlap in practice: both end up asking whether what was published carries provenance somebody else can read.

European Union

AI Act, Article 50

Providers must ensure synthetic output carries machine-readable disclosure that is effective, interoperable, robust and reliable. Deployers must disclose deepfakes and AI-generated text published on matters of public interest, with or without intent to deceive.

California

SB 942, as amended by AB 853

Covered providers must attach latent disclosures carrying provider, system name and version, creation time and a unique identifier, offer a user-visible disclosure that is hard to remove, and publish a free detection tool. Large online platforms must read provenance data from 1 January 2027.

Where this goes next

2027 and 2028

Platform provenance reading duties land on 1 January 2027 and capture device disclosure on 1 January 2028. China's labelling measures already apply. The assessment flags the ones that need planning now.

A score is not a control.

Disclosure is the easy half. Governing who may claim, keeping provenance durable through distribution, and being able to show what was asserted a year later is the half that needs infrastructure.
