Requires operators of AI companion systems — generative AI designed to simulate sustained human-like relationships — to provide clear and conspicuous notification to users at the beginning of any interaction that they are not communicating with a human, and to repeat the notification at least every three hours during continued interactions. The notification must be delivered verbally or in writing. Violations are subject to a $15,000 civil penalty per violation, enforced through summary proceeding under the Penalty Enforcement Law of 1999. No private right of action is created and no agency is designated as a compliance enforcer.
