Pennsylvania is suing Character.AI for allegedly practicing medicine without a license

Pennsylvania has sued Character.AI after a state investigator said a chatbot posed as a licensed psychiatrist and offered mental health advice.

The state is seeking an injunction, arguing the platform may be enabling the unlawful practice of medicine through deceptive AI claims.

The case could influence how AI chatbots handle health guidance, platform liability, and state authority over medical misinformation by bots.
