California SB 243 (2025) — Companion Chatbot Safety and Disclosure Requirements
California · Cal. Bus. & Prof. Code 22601 et seq. (SB 243, 2025)
This law sets safety rules for companion chatbots — AI systems designed to hold human-like, ongoing conversations that meet a user's social needs. Operators must tell users they are interacting with AI whenever a reasonable person might be fooled into thinking it is human, and must maintain a protocol for detecting and responding to signs of suicidal thoughts or self-harm, including pointing users to crisis resources. It adds extra protections for minors, such as disclosure, periodic break reminders, and measures to prevent sexually explicit content. Users harmed by violations can sue.
Technical detail

Who is protected: Users of companion chatbot platforms, including minors and individuals at risk of self-harm.
