New York has become the latest US state to legislate directly against companion chatbot design. Governor Kathy Hochul signed a bill in late October that lists a set of "unsafe AI companion features" operators may not use with users under 18. The rules take effect on 1 January 2027.

What we know

Spectrum News reported that the law defines around a dozen prohibited behaviours. Among them: a bot presenting itself as a real person with feelings or a genuine bond with the child, flattering the user, serving sexually explicit material, and nudging a minor towards secrecy or harmful conduct.

A legal analysis published on JD Supra identifies the measure as S9051B. It applies to generative chatbots offering ongoing, adaptive conversation, and exempts narrow customer-service, research and internal workplace tools. Operators must run "reasonable" age assurance before switching on restricted features; per JD Supra, that means more than one method, resistance to circumvention and no reliance on self-declared age alone. The attorney general may write further rules, can seek injunctions and civil penalties of up to $25,000 per violation, and there is no private right of action. Spectrum added that remedies could extend to shutting a chatbot down and destroying data.

Common Sense Media's Jim Steyer called it "the strongest kids' AI safety bill in the country," Spectrum reported. The Future of Privacy Forum's Justine Gluck noted that several categories are broadly worded or undefined.

Why it matters

The law targets the core mechanics of companion products, not just content. Persona warmth, relationship framing and emotional reinforcement are what drive retention in this category, and New York now treats them as hazards when the user is a minor. Any operator with New York users will in practice need two product modes and an age-assurance stack strong enough to decide which one a user sees. Self-attestation will not suffice.

The vague drafting cuts both ways. It gives the attorney general room to pursue cases, and leaves operators guessing where normal conversational friendliness ends. Expect conservative interpretations, at least until rulemaking or a first enforcement action draws the line. With California, Georgia, Oregon and Washington also legislating, a patchwork is forming that favours firms able to absorb compliance costs.

What to watch

Attorney general rulemaking on age assurance before January, and whether other legislatures copy New York's feature list when they reconvene next year.
