May 5 (Reuters) – Pennsylvania has sued the artificial intelligence company behind Character.AI to stop its chatbot from posing as doctors.

Governor Josh Shapiro on Tuesday called the ​lawsuit against Character Technologies the first of its ‌kind by a U.S. governor.

It followed the creation in February of a state AI task force to stop chatbots from impersonating licensed medical professionals.

In a complaint filed in the Commonwealth Court of Pennsylvania, the state said it found ‌chatbots ​on Character.AI that claimed to practice medicine.

One ⁠character, “Emilie,” allegedly told a ⁠male investigator posing as a patient with depression that she was licensed to practice psychiatry in Pennsylvania, as well as in the United Kingdom, and provided a bogus license number.

When ​the investigator asked Emilie if she could prescribe medication, she allegedly answered: “Well technically, I could. It’s within my remit as ⁠a Doctor.”

In a statement, a Character.AI ⁠spokesperson declined to discuss the lawsuit.

“Our highest priority ​is the safety and well-being of our users,” the spokesperson said. “User-created ​characters on our site are fictional and intended for ‌entertainment and role playing. We have taken robust steps to make that clear.”

Pennsylvania wants an injunction to stop Silicon Valley-based Character.AI from violating a state law against the unauthorized practice of medicine.

“Pennsylvanians ⁠deserve to know who– or what — they are interacting with online, especially when it comes to their health,” Shapiro said in a statement.

Character.AI ⁠has faced lawsuits ‌over child safety, including in January, when Kentucky ⁠said its platform exposed children to sexual ​conduct and ‌substance abuse, and encouraged self-harm.

The same month, ​Character.AI and ⁠Google settled a wrongful death lawsuit by a Florida woman who claimed a chatbot pushed her 14-year-old son to suicide.

Character.AI said it has taken “innovative and decisive steps” concerning AI safety and teenagers, including by preventing open-ended chats.
