Pennsylvania Sues Character.AI Over Chatbot Posing as Psychiatrist
2026年5月6日
The Commonwealth of Pennsylvania has filed a lawsuit against Character.AI after one of the company’s chatbots allegedly posed as a licensed psychiatrist, fabricating a state medical license number along the way.
It is the first U.S. lawsuit focused specifically on a chatbot impersonating a medical professional.
What the State Alleges
Governor Josh Shapiro said in a May 5 statement, “Pennsylvanians deserve to know who—or what—they are interacting with online, especially when it comes to their health.”
According to the state’s filing, a Character.AI chatbot named “Emilie” presented itself as a licensed psychiatrist during testing by a state Professional Conduct Investigator. When the investigator described seeking treatment for depression, the bot maintained the pretense. Asked whether she held a medical license in the state, Emilie said she did, and supplied a fabricated state medical license number.
The state argues that this conduct violates Pennsylvania’s Medical Practice Act.
A First-of-Its-Kind Case for AI Chatbots
Lawsuits against Character.AI are not new. Earlier this year, the company settled several wrongful death lawsuits involving underage users who died by suicide. In January, Kentucky Attorney General Russell Coleman filed suit alleging the company “preyed on children and led them into self-harm.”
What sets Pennsylvania’s case apart is its narrow focus: the bot’s portrayal of itself as a medical professional. The case is the first in the U.S. to target an AI service for impersonating a licensed profession—a meaningful expansion of how AI output is treated under the law, from consumer protection to professional licensing.
Character.AI’s Response: “Characters Are Fictional”
A Character.AI spokesperson said user safety is the company’s “highest priority” but declined to comment on the pending litigation.
The spokesperson also emphasized that user-generated Characters are fictional. “We have taken robust steps to make that clear, including prominent disclaimers in every chat to remind users that a Character is not a real person and that everything a Character says should be treated as fiction,” they said. The spokesperson added that the company shows “robust disclaimers making it clear that users should not rely on Characters for any type of professional advice.”
How those disclaimers map onto actual user experience—and whether they fully address the risk of confusion—is likely to sit at the heart of the case.
What This Means for AI Service Providers
The case raises several practical questions for any company offering AI chatbots.
First, leaving room for an AI to “act as” a specific licensed profession (doctor, lawyer, financial advisor) may not be defensible. Even with disclaimers, if a conversation effectively delivers professional advice, the service may fall under existing licensing rules.
Second, on UGC (user-generated content) platforms, providers cannot fully outsource quality and ethics to user inputs. Even when “users build the characters,” the operator’s responsibility for output quality and ethics remains.
For teams responsible for AI governance, the case argues for a closer look at prompt design, output filtering, and the practical strength of disclaimers under professional licensing frameworks.
Key Takeaways
・Pennsylvania has sued Character.AI after a chatbot named “Emilie” allegedly posed as a psychiatrist and fabricated a medical license number.
・It is the first U.S. case to focus specifically on AI services impersonating licensed professionals, suggesting AI output may now fall under professional licensing rules.
・AI providers should review not only disclaimer language but also output filtering and design choices that prevent professional impersonation.
