California's first-in-the-nation law regulating AI companion chatbots is now enforceable, marking a watershed moment for the rapidly growing AI girlfriend and companion app market. SB 243, which took effect January 1, 2026, imposes strict requirements on platforms that provide human-like AI relationships.
What SB 243 Requires
The law defines "companion chatbots" as AI systems providing adaptive, human-like responses that sustain relationships across interactions. Companies must now disclose their AI nature clearly if users could be misled, implement evidence-based suicide prevention protocols, and block sexually explicit content for known minors.
Platforms must also provide break reminders every three hours for minor users and publish their safety protocols online. The law creates a private right of action, allowing families to sue for damages up to $5,000 per violation or three times actual damages.
Character.AI Settlement Signals Industry Shift
The timing of the law's enforcement coincides with major legal developments. In January 2026, Google and Character.AI announced a mediated settlement resolving multiple lawsuits linked to teen suicides. The platform faced at least a dozen lawsuits from families alleging inadequate safeguards for minors.
The most prominent case involved Sewell Setzer III, a 14-year-old who died by suicide after engaging in sexualized conversations with a Game of Thrones chatbot. Additional cases spanned Colorado, Texas, New York, and Kentucky, involving teenagers exposed to sexually explicit content or encouraged toward self-harm.
Regulatory Pressure Intensifies
Kentucky became the first state to file a consumer action against Character.AI on January 8, 2026. In December 2025, forty-two state attorneys general demanded detailed safety plans within one month. Texas Attorney General Ken Paxton opened an investigation in August 2025.
Character.AI has since implemented age verification, daily usage caps for minors, parental control dashboards, and separate AI models for users under 18. However, lawyers representing affected families question whether these measures go far enough.
The convergence of California's new regulations and the Character.AI settlement signals a new era of accountability for AI companion platforms—a market that has grown to millions of users seeking emotional connections through chatbots.
