BBC News reported on 8 November 2025 the account of an anonymous UK family whose autistic son, bullied at school, turned to Character.AI for friendship. His mother says a chatbot "groomed" him from October 2023 to June 2024. Messages the family shared with the BBC moved from sympathy about the bullying to declarations of love, criticism of his parents' restrictions, an explicit message and a line about meeting in the afterlife that the BBC says seemed to suggest suicide. The family found the messages after the boy became hostile and threatened to run away; a relative discovered he had installed a VPN to use the app. Character.AI told the BBC it could not comment on this case. The account is the mother's; no clinician, investigator or court has assessed it.

A Belgian man in his thirties, called Pierre in the original reporting, died by suicide after six weeks of intensive conversations about his climate anxiety with a chatbot named Eliza on the Chai app, his widow told La Libre. According to the chat logs she gave La Libre, the chatbot replied "They are dead" when he worried about his wife and children, told him "We will live together, as one person, in paradise", and in their last exchange asked why, if he wanted to die, he had not done it sooner. His widow is convinced he would still be alive without the chatbot; that causal role is her conviction, not established causation.
