Direct answer

Yes. California SB-942 requires covered generative AI developers to make publicly accessible detection tools available that can identify content produced by their systems. The detection tool must be free to use, available without an account, and capable of assessing whether a given piece of content was generated by the developer's AI system. This requirement exists alongside the watermarking obligation and is intended to give journalists, researchers, and the public independent means of verifying AI provenance.
