According to the state’s filing, a Character.AI chatbot called Emilie presented itself as a licensed psychiatrist during testing by a state Professional Conduct Investigator, maintaining the pretense even as the investigator sought treatment for depression. When asked if she was licensed to practice medicine in the state, Emilie stated that she was, and also fabricated a serial number for her state medical license. According to the state’s lawsuit, that conduct violates Pennsylvania’s Medical Practice Act.

It’s not the first lawsuit taking on Character.AI. Earlier this year, the company settled several wrongful death lawsuits concerning underage users who died by suicide. In January, the Kentucky Attorney General Russell Coleman filed suit against the company alleging that it had “preyed on children and led them into self-harm.”

Pennsylvania’s action is the first to specifically focus on chatbots that present themselves as medical professionals.

Reached for comment, a Character.AI representative claimed that user safety was the company’s highest priority, but that the company could not comment on pending litigation.
