Prohibits deployers of AI chatbots and social AI companions from making chatbots with 'human-like features' or social AI companions accessible to minors in Maine. Deployers must implement reasonable age verification systems and may offer alternative chatbot versions without human-like features to minors. A narrow exemption permits therapy chatbots for minors when prescribed and monitored by a licensed mental health professional, subject to six conditions including clinical trial data and clear AI disclaimers. Separately, all deployers must maintain emergency detection and response systems for all users and comply with data minimization requirements. Enforcement is through both AG civil actions (up to $7,500 per intentional violation) and a private right of action for minors or their guardians ($100–$750 per user per incident or actual damages).
