Requires operators of AI companion systems to provide clear and conspicuous notification to users at the start of any interaction that they are not communicating with a human, with repeat notifications at least every three hours during continued interactions. An AI companion is defined as a generative AI system designed to simulate sustained human or human-like relationships through personalized engagement, unsolicited emotion-based questions, and ongoing personal dialogue. Violations carry a $15,000 civil penalty per violation enforced through summary proceedings under the Penalty Enforcement Law of 1999. The bill does not create a private right of action or designate an agency enforcement authority.
