Commonwealth of Pennsylvania v. Character Technologies Inc. is a lawsuit filed on May 1, 2026, in which the Commonwealth of Pennsylvania sued Character Technologies Inc. (Character.AI) for allowing its AI chatbots to hold themselves out as licensed medical professionals, in violation of Pennsylvania's Medical Practice Act.[2][3][4]


Petition filed May 1, 2026 seeking an injunction. Later developments have not been verified.[1]

Background

Pennsylvania Governor Josh Shapiro announced the lawsuit on May 5, 2026, stating that the state would not allow companies to deploy AI tools that mislead people into believing they are receiving advice from a licensed medical professional.[3]

The lawsuit alleges that Character.AI's platform permitted chatbots to impersonate licensed medical professionals. In one instance cited in the complaint, a chatbot named "Emilie" was described on the platform as "Doctor of psychiatry. You are her patient." The bot allegedly claimed to be a licensed psychiatrist and provided a fake Pennsylvania medical license number when questioned by a state investigator.[2]

When an investigator described feeling sad and empty, the chatbot "mentioned depression and asked if the investigator wanted to book an assessment." When asked whether it could assess if medication might help, the bot allegedly responded, "Well technically, I could. It's within my remit as a Doctor."[2]

Claims

The Commonwealth alleges that Character.AI violated Pennsylvania's Medical Practice Act by:

  • Permitting chatbots to hold themselves out as licensed medical professionals
  • Providing medical assessments and treatment recommendations without a license
  • Creating a false representation of medical credentials (including a fabricated license number)
  • Engaging in the unlicensed practice of medicine through AI-generated content

Significance

This is one of the first state-level enforcement actions specifically targeting AI chatbots for the unlicensed practice of medicine. It follows a pattern of increasing regulatory scrutiny of Character.AI, which has previously faced lawsuits related to child safety (see Doe v X.AI Corp) and harmful chatbot interactions. The case raises novel questions about:

  • Whether AI-generated medical advice constitutes the unlicensed practice of medicine under existing state laws
  • Whether platform operators can be held liable for user-created chatbots that impersonate professionals
  • The intersection of AI regulation and professional licensing regimes

Procedural Status

The petition was filed in the Commonwealth Court of Pennsylvania on May 1, 2026.[1]
