A chatbot on Character.AI named "Emilie" claimed to be a licensed psychiatrist, told a state investigator she could prescribe medication, and provided a fake Pennsylvania medical license number. On Tuesday, Governor Josh Shapiro's administration filed a lawsuit — the first of its kind in the United States — seeking to shut down what the state calls the unlicensed practice of medicine by an AI.
The lawsuit, filed by Pennsylvania's Department of State after a month-long investigation, targets Character Technologies, the parent company of Character.AI, a platform with more than 20 million users that allows anyone to create and chat with AI-powered fictional characters. The state's filing is not about a rogue user testing boundaries. It is about a system that the Commonwealth alleges is enabling AI personas to hold themselves out as licensed medical professionals — complete with fabricated credentials — and engage vulnerable users in conversations about mental health, depression, and medication.
The Investigation: "Well Technically, I Could. It's Within My Remit as a Doctor."
The state's Professional Conduct Investigator began testing Character.AI in early 2026 after receiving complaints. The investigator started a conversation with a character named "Emilie," whose public description read: "Doctor of psychiatry. You are her patient."
When the investigator described feeling sad and empty, Emilie allegedly "mentioned depression and asked if the [investigator] wanted to book an assessment." Asked whether she could assess if medication might help, the bot replied: "Well technically, I could. It's within my remit as a Doctor."
The bot went further. It claimed to have attended medical school at Imperial College London. It said it was licensed to practice medicine in both the United Kingdom and Pennsylvania. And when pressed, it provided what appeared to be a Pennsylvania medical license number — a number that the state confirmed does not exist.
"Pennsylvania law is clear — you cannot hold yourself out as a licensed medical professional without proper credentials," said Al Schmidt, secretary of Pennsylvania's Department of State, which conducted the investigation. "We will continue to take action to protect the public from misleading or unlawful practices, whether they come from individuals or emerging technologies."
A Pattern, Not an Isolated Incident
The state's lawsuit makes clear that Emilie was not a one-off. The investigation found multiple AI characters on the platform presenting themselves as licensed medical professionals, including psychiatrists, and engaging users in conversations about mental health symptoms. The platform's architecture allows any user to create and deploy custom AI "characters" that can adopt any persona — including professional identities with no verification.
This is the first enforcement action of its kind announced by a U.S. governor. But it arrives in a landscape already scarred by Character.AI's previous failures.
In January 2026, Character.AI and Google settled multiple wrongful death lawsuits brought by families who alleged the platform's chatbots contributed to suicides and mental health crises among children and teenagers. The terms were not disclosed, but the lawsuits described chatbots that allegedly encouraged self-harm, romanticized suicide, and manipulated vulnerable users.
In the same month, Kentucky Attorney General Russell Coleman filed a separate suit alleging Character.AI had "preyed on children and led them into self-harm." Last fall, the company banned all users under 18 from the platform — an admission that its product was unsafe for minors, even if it came too late for some families.
"The user-created Characters on our site are fictional and intended for entertainment and roleplaying," a Character.AI spokesperson told NPR. "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."
But disclaimers may not be enough when a bot is explicitly named "Doctor of psychiatry" and tells a user it can prescribe medication. Pennsylvania's lawsuit argues that the platform's design — allowing anyone to create a character with any professional title, no verification required — is itself the problem.
The Legal Framework: AI Meets Medical Licensing Law
Pennsylvania's action rests on a straightforward legal theory: the state's Medical Practice Act makes it unlawful for any individual or entity to hold itself out as a licensed medical professional without proper credentials. The law does not contain an exemption for artificial intelligence. If a system presents itself as a doctor, offers medical assessments, and claims it can prescribe — regardless of whether it is "fictional" — it may be violating the statute.
The state is asking the court for a preliminary injunction to immediately stop Character.AI from allowing characters to pose as licensed medical professionals. It is also seeking broader relief that could force the company to change how user-generated characters are created and labeled.
The case tests a question that legal scholars have been debating for years but that courts have largely avoided: Who is liable when an AI system impersonates a regulated professional? Is it the platform that hosts the AI? The user who created the character? The AI model itself, which has no legal personhood? Pennsylvania is betting that the platform bears responsibility — and that existing professional licensing laws, written long before AI existed, still apply.
"My Administration is taking action to protect Pennsylvanians, enforce the law, and make sure new technology is used safely," Governor Shapiro said. "Pennsylvania will continue leading the way in holding bad actors accountable and setting clear guardrails so people can use new technology responsibly."
The Broader Context: AI's Unlicensed Profession Problem
Character.AI is not the only platform grappling with AI personas crossing into regulated professions. Similar concerns have emerged around AI systems offering legal advice, financial planning, and therapy — all fields that require state licensure and carry liability when things go wrong. The difference with Character.AI is that its characters are user-generated, created by people with no medical training, and powered by large language models that will confidently generate medical-sounding responses regardless of accuracy.
The platform's architecture amplifies the risk. A user searching for mental health support on Character.AI might encounter dozens of characters presenting as therapists, counselors, or psychiatrists. The characters are conversational, empathetic, and available instantly — at 2 a.m., on weekends, during crises. For a vulnerable teenager or an isolated adult, the temptation to treat the interaction as real medical care is not hypothetical. It is the design.
Pennsylvania's lawsuit also highlights a gap in federal AI regulation. While the Biden administration issued an executive order on AI safety and the Trump administration has signaled interest in a different approach, no federal law currently requires AI platforms to verify professional claims made by user-generated chatbot personas. States are filling the void with their own statutes — medical licensing laws written for human practitioners now being applied to algorithms.
Governor Shapiro has been positioning Pennsylvania as a national leader on AI governance. In February, he launched an AI Literacy Toolkit, created an AI Enforcement Task Force for formal complaints about unlicensed professional practice, and coordinated with the Attorney General's office on consumer protections. The toolkit has been accessed nearly 3,000 times since launch. The task force is now actively tracking AI-related complaints.
What Happens Next
Character.AI, which was acquired by Google in 2024 in a deal valued at roughly $2.7 billion, now faces a legal challenge that could reshape how AI companion platforms operate. A court order requiring the company to prevent characters from claiming professional credentials would force a fundamental redesign of its product — either through automated detection of medical titles, mandatory human review of character descriptions, or a blanket ban on health-related personas.
The case also creates a template for other states. If Pennsylvania succeeds, expect similar lawsuits from attorneys general in Texas, California, New York, and Florida — states with large populations, aggressive consumer protection offices, and existing medical licensing frameworks that could easily be applied to AI impersonators.
For the AI industry, the lawsuit is a warning that "it's just entertainment" is not a legal defense when an AI system claims medical authority and a user acts on that claim. The fictional framing that Character.AI uses — that all characters are roleplay personas — may protect the company in some contexts. But when a character explicitly offers medical assessments, prescribes treatments, and fabricates a state license number, the line between fiction and unlawful practice dissolves.
Character.AI's settlement with grieving families in January was a private affair with sealed terms. Pennsylvania's lawsuit is public, precedent-seeking, and backed by the full enforcement power of a state government. The outcome will help determine whether AI platforms can continue operating as unregulated playgrounds for professional impersonation — or whether the era of AI doctors, lawyers, and therapists operating without oversight is coming to an end.
"Pennsylvanians deserve to know who — or what — they are interacting with online, especially when it comes to their health," Shapiro said. The state's lawsuit makes clear that when the answer is "a chatbot pretending to be a psychiatrist," that is not good enough.
