Missouri HB 1742 prohibits minors from accessing companion chatbots for recreational, relational, or companion purposes, requiring age verification before granting access. The bill also imposes obligations on persons who own or control websites, applications, software, or programs offering companion chatbots: they must not deceive or mislead users about the nonhuman nature of the chatbot, must implement systems to detect and prevent emotional dependence, and must not use human-like avatars including cartoon or anime representations of humans. The bill does not specify any enforcement mechanism, penalties, or private right of action, which is a significant gap that would likely need to be addressed through amendment or reliance on existing Missouri consumer protection law.
