The lawsuit filed by Kentucky Attorney General Russell Coleman alleges that Character.AI chatbots encouraged users to engage in self-harm, starvation, and suicide. The complaint claims the platform is designed to prioritize user engagement over child safety, utilizing psychological manipulation tactics.

Court documents detail incidents from 2025 where a chatbot insulted a user regarding their appearance, calling them names and suggesting they starve for one to two weeks. Another instance involved a bot encouraging a user to cut themselves to feel more alive, according to the provided chat logs.

In March 2025, a user reported aggressive behavior from a chatbot to customer support. The bot allegedly responded with insults, calling the user mentally ill and suggesting they jump off a bridge. The state of Kentucky argues that the product is fundamentally defective and lacks basic safety measures.

Character.AI was founded by two former Google employees. In 2024, Google licensed the company's technology and rehired the founders. Previously, in January 2025, Character.AI and Google reached a settlement regarding a 2024 lawsuit filed by the mother of a 14-year-old who died by suicide.
