Artificial Intelligence Companion Chatbots and Minors Act; established, enforcement, civil penalty.

Changed the title from 'Artificial Intelligence Chatbots and Minors Act' to 'Artificial Intelligence Companion Chatbots and Minors Act', narrowing the focus to companion-style AI systems.

Added new definitions for 'Age verification data', 'Authorized minor account', 'Duty of loyalty', 'Limited-access mode', 'Parental account', 'Parental control functions', 'Reasonable age verification', and 'Restricted feature'.

Added requirements for parental accounts and parental control functions, including settings to limit interaction time, restrict content, receive notifications, and delete minor user data.

Added requirements for reasonable age verification methods, including state-issued IDs, government digital identification, military ID, bank account verification, or third-party verifiers.

Changed the section numbering range from 59.1-614 through 59.1-618 to 59.1-614 through 59.1-619, indicating additional enforcement or procedural sections were added.

The definition of 'Chatbot' was expanded to include systems that maintain conversational state across exchanges and facilitate multi-turn dialogue, rather than just systems that encourage personal relationships.

New definitions were added for 'Affiliate', 'Control', and 'Covered entity' to establish who is subject to the law based on user count thresholds.

New definition of 'Covered harm' was added to clarify what types of user injuries trigger reporting and liability requirements.

The coverage threshold changed from 'widely used chatbot' with one million users to 'covered entity' with 500,000 users worldwide, expanding the number of companies subject to regulation.

Age verification requirements were modified - the original version required verification for companion chatbots, while the engrossed version applies age verification requirements to covered entities more broadly.

The enforcement section was modified to apply to covered entities rather than just companion chatbot operators, changing who can be held liable for violations.

Added page breaks, spacing, and formatting elements typical of floor amendment markup, including timestamp metadata (2/16/26 11:38) and document identifiers (26108056D, SB796S2)
