AI disclosure rules for YouTube in California
Yes — publishing realistic AI-generated or AI-edited content on YouTube in California can legally require a disclosure. Here is what applies and the exact wording to use.
YouTube requires disclosing realistic altered or synthetic content
When you upload content that is realistic and was meaningfully altered or generated with AI, you must tick 'Altered or synthetic content' in YouTube Studio. YouTube then shows a label in the description (and a more prominent label on the video for sensitive topics like health, news, elections, finance). Clearly unrealistic, animated, or trivially-edited content is exempt.

California AI Transparency Act (SB 942) — provenance & detection duties
SB 942 (California AI Transparency Act) targets large 'covered providers' of generative AI (systems with high monthly user counts): they must offer a free AI-detection tool and embed both latent (machine-readable) and optional manifest (visible) disclosures in AI outputs. Amended by AB 853 (signed Oct 2025): a covered provider is a GenAI system with over 1,000,000 monthly users; the operative date moved to 2 Aug 2026, and from 1 Jan 2027 the duties also reach generative-AI hosting platforms.
