Official summary

Legislative Counsel’s Digest (official, as of the latest version). Written by nonpartisan legislative staff; reproduced verbatim.

Existing law requires that if a reasonable person interacting with a companion chatbot, as defined, would be misled to believe that the person is interacting with a human, an operator of a companion chatbot platform must issue a clear and conspicuous notification indicating that the companion chatbot is artificially generated and not human. Existing law requires a chatbot operator to maintain a protocol for preventing the production of suicidal ideation, suicide, or self-harm content to the user, as specified, and would require an operator to publish details on that protocol on the operator’s internet website. Existing law requires an operator to take certain actions with respect to a user the operator knows is a minor, including instituting reasonable measures to prevent the companion chatbot from producing sexually explicit visual material or proposing sexually explicit conduct.

This bill would instead require a companion chatbot operator to take the above actions when it has constructive knowledge that a user is a minor. This bill would instead require an operator to prevent its companion chatbot from producing or facilitating the exchange of any sexually explicit material or proposing sexually explicit conduct.
