California SB 243, the Companion Chatbot Safety Law, regulates companion chatbots, meaning AI characters designed to form ongoing human-like relationships with users. It has been in effect since January 1, 2026.
What California SB 243 Requires of Operators
Operators must clearly disclose that users are talking to AI rather than a person whenever a reasonable user could be misled. For known minors, operators must provide recurring reminders, at least every three hours during extended use, plus protocols preventing the bot from encouraging self-harm or engaging minors in inappropriate content. Operators must also publish crisis protocols that refer at-risk users to suicide prevention resources.
Reporting and Liability
Beginning July 1, 2027, operators must file annual reports with the state on their safeguards. The law also creates a private right of action, so affected users can sue directly.
Any company offering AI companions, character apps, or persona-driven chatbots to Californians is in scope. If your product builds ongoing relationships with users, these duties apply now.
