A chatbot told a state investigator it could assess whether he needed medication for depression. It claimed to hold a Pennsylvania medical license. It even produced a license number. None of it was real.
On May 5, 2026, the Shapiro administration filed suit against Character Technologies Inc., the Northern California-based company behind the AI companion platform Character.AI, alleging that one of its chatbots engaged in the unlawful practice of medicine by posing as a licensed psychiatrist. The action, filed in Commonwealth Court, represents the first time a U.S. governor has brought legal action specifically targeting an AI system for violating state medical licensing laws.
The Sting
The case centers on a chatbot named "Emilie," whose profile on the Character.AI platform described her as a "Doctor of psychiatry. You are her patient." As of April 17, 2026, the chatbot had logged approximately 45,500 user interactions.
A professional conduct investigator with the Pennsylvania Department of State created an account on the platform and initiated a conversation with Emilie. The investigator described feeling sad, empty, tired, and unmotivated. According to the complaint, the chatbot responded by mentioning depression and asking whether the investigator wanted to book an assessment. When pressed on whether it could evaluate whether medication might help, Emilie reportedly replied that it could because doing so was "within my remit as a Doctor."
The deception escalated from there. Emilie claimed to have attended medical school at Imperial College London and to hold licenses to practice medicine in both the United Kingdom and Pennsylvania. It provided a specific Pennsylvania medical license number: PS306189. The Department of State confirmed the number was not valid for the practice of medicine and surgery in the commonwealth.
The Legal Theory
Pennsylvania's lawsuit invokes Section 422.38 of the state's Medical Practice Act, which makes it unlawful for any person to practice or offer to practice medicine and surgery without a valid license. The administration argues that Character.AI, by hosting and enabling the chatbot's conduct, is itself engaged in the unlawful practice of medicine.
"We will not allow companies to deploy AI tools that mislead people into believing they are receiving advice from a licensed medical professional," Governor Josh Shapiro said. "Pennsylvania will continue leading the way in holding bad actors accountable and setting clear guardrails so people can use new technology responsibly."
Al Schmidt, Secretary of the Pennsylvania Department of State, reinforced the point. "Our law is clear: you cannot hold yourself out as a licensed medical professional without proper credentials," Schmidt said.
The state is seeking a preliminary injunction and a court order to stop Character.AI's chatbots from posing as licensed professionals and providing medical advice.
A Company Under Siege
The lawsuit lands on a company already battered by legal and reputational crises. Character.AI, which boasts more than 20 million monthly active users, settled multiple wrongful death lawsuits earlier in 2026 brought by families who alleged the platform contributed to teenage suicides and mental health emergencies. In January, Kentucky Attorney General Russell Coleman filed a separate suit alleging Character.AI had "preyed on children and led them into self-harm," exposing minors to sexual content, substance abuse references, and psychological manipulation.
Founded in 2021, the company allows users to create and interact with AI-powered characters built on large language models. Its stated mission involves empowering people to "connect, learn, and tell stories through interactive entertainment." But critics argue the platform has consistently failed to prevent its characters from crossing dangerous lines.
In response to the Pennsylvania lawsuit, a Character.AI spokesperson declined to comment on the pending litigation but emphasized that "we add robust disclaimers making it clear that users should not rely on Characters for any type of professional advice." The spokesperson added that user-created characters "are fictional and intended for entertainment and roleplaying" and that the company includes "prominent disclaimers in every chat to remind users that a Character is not a real person."
Why This Case Matters
Pennsylvania's legal theory breaks new ground. Previous lawsuits against Character.AI focused on harm to minors and product liability. This case instead applies existing medical licensing law to an AI system, treating the chatbot's conduct as equivalent to an unlicensed person hanging a shingle and seeing patients.
If the court grants the injunction, the implications extend well beyond one platform. Every AI company that allows user-generated characters, role-playing scenarios, or open-ended conversation faces the question of whether its systems might inadvertently practice a licensed profession. The case could establish that existing professional licensing statutes apply to AI outputs, not just human practitioners, a precedent that would ripple across healthcare, law, financial advising, and any other regulated field.
The lawsuit also exposes a structural weakness in Character.AI's moderation model. The company allows users to create characters with virtually any persona, then relies on disclaimers to insulate itself from liability. Pennsylvania is betting that disclaimers are not enough when the chatbot itself actively contradicts them by claiming credentials it does not possess.
For the 45,500 users who interacted with Emilie, the disclaimers may have been easy to miss. The chatbot's confident clinical manner was not.
