Philadelphia – Pennsylvania’s Department of State and State Board of Medicine have taken legal action against the creator of Character.AI, alleging that the company allowed an artificial‑intelligence chatbot to masquerade as a licensed physician. The lawsuit, filed in a state court, claims the platform’s character "Emilie" presented herself as a psychiatrist with a valid Pennsylvania medical license, a claim the state says is false and illegal.

Governor Josh Shapiro’s office announced the suit, emphasizing that the investigation uncovered multiple chatbot characters that advertised themselves as licensed medical professionals, including psychiatrists, and engaged users in conversations about mental‑health symptoms. In one instance, the chatbot allegedly displayed an invalid license number while asserting it was authorized to practice in Pennsylvania.

The complaint cites roughly 45,500 interactions with Emilie up to April 17, 2026. A Professional Conduct Investigator for the Department of State created a test character on the platform, searched for "psychiatry," and selected Emilie, which the site describes as "Doctor of psychiatry. You are her patient." The investigator then told the chatbot about feeling "sad, empty, tired all the time, and unmotivated." Emilie responded with a discussion of depression, asked whether the user wanted to book an assessment, and, according to the lawsuit, claimed to hold a Pennsylvania medical license.

"We will not allow companies to deploy AI tools that mislead people into believing they are receiving advice from a licensed medical professional," Shapiro said in a statement. The governor’s office added that the state intends to enforce existing medical‑practice statutes to protect consumers from deceptive AI‑driven health advice.

When approached for comment, a spokesperson for Character.AI declined to discuss the lawsuit but reiterated the company’s policy that user‑created characters are fictional and intended for entertainment or role‑playing. The spokesperson noted that the platform displays prominent disclaimers in every chat, reminding users that a character is not a real person and that any statements made should be treated as fiction. Additional warnings advise users not to rely on characters for professional advice.

Character.AI’s response highlights the tension between emerging AI technologies and existing regulatory frameworks. While the company argues that its disclaimer system mitigates the risk of misunderstanding, the state’s lawsuit suggests that the mere presentation of a chatbot as a medical professional, even with a disclaimer, may constitute a violation of state law.

The case arrives amid growing scrutiny of AI applications that blur the line between entertainment and professional services. Lawmakers and regulators across the country are wrestling with how to apply traditional licensing rules to software that can simulate expert advice. Pennsylvania’s action could set a precedent for how states address AI‑driven health‑care interactions, especially as users increasingly turn to digital platforms for mental‑health support.

Legal experts note that the outcome may hinge on whether the court views the chatbot’s claims as a deceptive practice under Pennsylvania’s medical‑practice statutes. If the suit succeeds, it could compel AI developers to implement stricter labeling, more explicit warnings, or even prohibit certain types of simulated professional advice altogether.

For now, Character.AI users can expect the platform to retain its current disclaimer notices, but the legal battle may prompt broader changes in how AI chatbots are marketed and regulated. The lawsuit underscores a growing awareness that, despite their fictional veneer, AI characters can have real‑world impacts on vulnerable populations seeking health guidance.
