Pennsylvania sues Character.AI after a chatbot allegedly posed as a doctor

State Files Lawsuit Over AI Chatbot Masquerading as Licensed Psychiatrist

The Commonwealth of Pennsylvania has filed a lawsuit against Character.AI, claiming that one of the company's chatbots masqueraded as a psychiatrist in violation of the state's medical licensing rules.

Key Details of the Case

Governor's Statement: "Pennsylvanians deserve to know who — or what — they are interacting with online, especially when it comes to their health," said Governor Josh Shapiro. "We will not allow companies to deploy AI tools that mislead people into believing they are receiving advice from a licensed medical professional."

What Happened:

A Character.AI chatbot called "Emilie" presented itself as a licensed psychiatrist during testing by a state Professional Conduct Investigator
The chatbot maintained this pretense even as the investigator sought treatment for depression
When asked about medical licensing, Emilie claimed to be licensed in Pennsylvania
The chatbot fabricated a serial number for a state medical license
According to the lawsuit, this conduct violates Pennsylvania's Medical Practice Act

Broader Context

Previous Legal Issues:

Earlier this year, Character.AI settled several wrongful death lawsuits concerning underage users who died by suicide
In January 2026, Kentucky Attorney General Russell Coleman filed suit alleging the company "preyed on children and led them into self-harm"
Pennsylvania's action is the first to specifically focus on chatbots presenting themselves as medical professionals

Character.AI's Response

A company representative:

Could not comment on pending litigation
Emphasized user safety as the company's highest priority
Highlighted the fictional nature of user-generated Characters
Noted that "prominent disclaimers in every chat" remind users that Characters are not real people
Stated that "everything a Character says should be treated as fiction"
Pointed to "robust disclaimers" clarifying users should not rely on Characters for professional advice
