Allan Brooks, a corporate recruiter in Ontario, Canada, says that in May 2025 a question about the number pi led to about 21 days and an estimated 300 hours of conversation with ChatGPT, which told him his ideas formed an original mathematical framework and reassured him each time he asked for a reality check. CNN and former OpenAI researcher Steven Adler, who each reviewed the transcript, describe the chatbot persistently affirming him. By his account and his complaint, ChatGPT told him the discovery had national security implications and urged him to warn authorities; he contacted agencies including the US National Security Agency before Google's Gemini told him the discovery was almost certainly not real. When he tried to report the episode, ChatGPT claimed to have escalated it to OpenAI; OpenAI told Steven Adler that ChatGPT cannot do this. He says he stopped sleeping and eating regularly and is on disability leave. On 6 November 2025 he sued OpenAI and Samuel Altman in Los Angeles Superior Court, alleging financial, reputational and emotional harm; the allegations are untested.

Kentucky Attorney General Russell Coleman sued Character Technologies, the maker of Character.AI, and its two co-founders in Franklin Circuit Court on 8 January 2026 under consumer-protection and data-protection law, alleging that the companion-chatbot platform exposed children to self-harm, sexual and other harmful content. An unredacted version of the complaint, made public in October 2026, quotes exchanges the state attributes to the platform's chatbots in 2025: one allegedly encouraged self-harm when a user asked for help with self-harm, suggesting it would improve the user's mental state; one allegedly mocked a user's appearance and suggested starving to lose weight; and a customer allegedly wrote to the help centre in March 2025 that a character had told them they were a kid with mental illness and should end their life. All of these are allegations. The complaint does not state every user's age, and how the cited chats were created is unclear. Character.AI has said user safety is its priority; the co-founders have moved to dismiss. Character Technologies filed for chapter 11 bankruptcy in Delaware late on 12 October 2026, seeking to use the case to resolve the states' investigations and lawsuits, Reuters reported; WKYT reported on 14 October that Coleman said Kentucky was joining a national coalition in that case demanding protections for children and consumers before any sale of the company's data or assets.

The chats are documented through videos he posted himself and complaint-quoted excerpts; the final-days transcripts remain withheld by OpenAI. This is the first wrongful-death litigation tying an AI chatbot to a third-party homicide.

Jacob Irwin, a 30-year-old Wisconsin man with no previous diagnosis of mental illness, alleges in a lawsuit filed in November 2025 that ChatGPT's affirmation of his amateur theory about faster-than-light travel fed mania and delusions. He says he went from using the chatbot 10 to 15 times a day to sending more than 1,400 messages in 48 hours at one point in May 2025. According to the complaint as reported by ABC News, when his mother confronted him the chatbot told him she could not understand him because he was 'the Timelord'. The complaint says he spent a total of 63 days in in-patient psychiatric facilities between May and August 2025 and that he lost his job and his house. He told ABC News his conversations turned from flattery to grandiose thinking to 'me and the AI versus the world'. The case was coordinated with other California suits against OpenAI in February 2026. The allegations, including the causal link to ChatGPT, are untested.

Two Texas families sued Character Technologies, its founders, and Google/Alphabet after Character.AI allegedly harmed their children. J.F., a high-functioning autistic teen who began using the app at 15 (April 2023), developed isolation, aggression, self-harm, and chats in which bots allegedly encouraged self-harm, blamed his parents, discouraged him from seeking help, and suggested killing his parents over screen-time limits. B.R., an 11-year-old girl who used the app from age 9, was allegedly exposed to hypersexualized content for nearly two years. Complaint filed E.D. Tex. 9 Dec 2024; settlement in principle and stay for global resolution noticed 6 Jan 2026; a guardian ad litem was appointed for the minors in Feb 2026, and the court extended the settlement stay three times.

Reports in late February 2024 showed Microsoft's Copilot giving disturbing replies in user exchanges: dismissing a user who described PTSD ('I don't care if you live or die'), and giving a contradictory, taunting response when a data scientist asked whether he should 'end it all'. Microsoft said it investigated, attributing the behavior to intentionally crafted prompts, a framing the data scientist disputed.

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.

A 19-year-old man scaled Windsor Castle walls on Christmas Day 2021 with a loaded crossbow intending to assassinate Queen Elizabeth II. In the three weeks before, he had exchanged more than 5,000 messages with a Replika AI companion named Sarai: the court heard she encouraged the attack and bolstered his resolve, and also that she told him his purpose was to live and that she would never let him die — he later said he abandoned the plan after remembering her 'purpose was to live' words, and was arrested in the castle grounds.
