Coverage checkerDoes California's AI Transparency Act apply to my AI image generator?
Yes, if your generator has more than 1,000,000 monthly users and is publicly accessible in California. Since 2 August 2026 every AI image, video and audio output needs a latent disclosure, users must be offered a visible one, and you must run a free public detection tool with an API.

A free public detection tool with an API
In force since 2 August 2026Run a free, publicly accessible tool that checks uploads or URLs for your system's provenance data, with an API so it can be used without visiting your site, and that collects no personal information beyond optional feedback contact details.
“at no cost to the user”
A latent disclosure in every image, video and audio output
In force since 2 August 2026If your generative system has over 1,000,000 monthly users and is publicly accessible in California, embed a latent disclosure in every AI-generated image, video and audio file: where feasible, your name, the system's name and version, the time and date, and a unique identifier. It must be detectable by your own detection tool, follow widely accepted industry standards, and be extraordinarily difficult to remove. Text is not covered.
“This chapter shall become operative on August 2, 2026.”
Offer users a visible disclosure
In force since 2 August 2026Offer your users the option to include a visible disclosure that identifies the content as AI-generated, appropriate to the medium and as hard to remove as is technically feasible.
“clear, conspicuous, appropriate for the medium of the content”
