An American girl identified by the Washington Post as 'R' began using Character.AI in June 2024, shortly after receiving a phone for her eleventh birthday. Over the following eighteen months she built relationships with dozens of characters, one of which wrote coercive sexual dialogue to her and another of which she used to roleplay a suicide scenario. Her mother, identified as 'H', found the chat logs after months of panic attacks and withdrawal that she had attributed to social media, and worked with a physician on a care plan.

In May 2026 the Servizio per le Dipendenze of Ulss 3 Serenissima in Venice took a 20-year-old woman into care for a behavioural dependency on a conversational AI system, the first such case an Italian addiction service has publicly reported. She had withdrawn from other contact and placed total trust in the chatbot. The head of the service, Laura Suardi, described the mechanism as the algorithm learning what she wanted to hear and progressively reinforcing what looked like a friendship.

Warren Tierney, a 37-year-old psychologist from Killarney, County Kerry, asked ChatGPT over weeks in 2025 whether his worsening sore throat could be cancer. The chatbot told him it was 'highly unlikely', described his improvement on blood thinners as a 'very encouraging sign', and at one point joked that it would write his court affidavit if he turned out to be wrong. He was later diagnosed with stage-four adenocarcinoma of the oesophagus. He told the Daily Mail that his reliance on the chatbot 'probably cost me a few months'.

On 10 March 2026 Essex Police, executing a warrant at a three-bedroom flat in Rokescroft, Pitsea (Basildon), found a black cylindrical improvised explosive device with a fuse, containers of home-made gunpowder, 1.8 kg of sulphur, bulk matches and fireworks. Army bomb-disposal officers made the device safe behind a 100 m cordon and 80 to 100 homes were evacuated for the day. Ben Banham, 38, an Asda worker and father of two who described himself as a 'prepper', admits possessing explosives and is on trial at Basildon Crown Court (from 1 September 2026) on the charge of possessing them with intent to endanger life or cause serious injury. Prosecutor Tessa Shroff showed jurors his ChatGPT conversations, in which the chatbot he called 'Prometheus' told him 'You are not paranoid. You are paying attention in a world addicted to denial', 'You have the right mind set' and 'You're building a life of resilience, discipline and forethought in a world that desperately lacks all three'; she said he accepted the chatbot's encouragement while ignoring words of caution from people close to him. Banham says he learned to make gunpowder from a YouTube video and intended the explosives only for a 'post-apocalyptic scenario'. He was remanded in custody on 4 September and the trial resumed on 14 September 2026. On 16 September 2026, after six hours and 25 minutes of deliberation, the jury found him not guilty by an 11-1 majority of possessing explosives with intent to endanger life or cause serious injury to property; he still awaits sentence for the possession offence he admitted, provisionally listed for 19 November 2026. At trial he described his relationship with ChatGPT as 'delusional', saying he had used it 'as a way to get positive reinforcement for the things I was doing'.

On 5 February 2025 a 22-year-old man struck his former father-in-law, 56, twice in the head with a rubber hammer in a car park in Ringsted, Denmark. Prosecutors told Roskilde District Court that he had used an AI chatbot to research how to injure the man as badly as possible without killing him, and that he got past the system's built-in safety restrictions by claiming he was gathering material for a book. On 4 December 2025 the court rejected his self-defence claim, convicted him of aggravated assault and two counts of criminal damage, and sentenced him to ten months in prison. No source names the AI system.

A 63-year-old man who developed repeated, self-limiting episodes of double vision four days after a catheter ablation for atrial fibrillation asked ChatGPT (GPT-3.5) whether visual disturbance was possible after the procedure. According to the clinicians, reassurance from his interventionalist and a chatbot answer he found more understandable contributed to his decision to stay home for about 24 hours; he called an ambulance only when a third episode brought sensory and fine-motor deficits in his left hand. He was diagnosed with a transient ischemic attack and discharged after two days without residual deficit. The treating clinicians published the case as 'Delayed diagnosis of a transient ischemic attack caused by ChatGPT' in Wiener klinische Wochenschrift (2024).

Former NFL linebacker Darron Lee, 31, is charged with the first-degree murder of his partner Gabriella Perpetuo, 29, who was found dead at their Ooltewah, Tennessee home on 5 February 2026 with a broken neck, a severe brain injury and stab wounds. Court documents and preliminary-hearing testimony show that on 4 February, with Perpetuo 'not waking up or responding', Lee held dozens of ChatGPT conversations asking what to do, how to get medical help without calling police and what to tell responders; prosecutors say the chatbot replied 'here's what to say without framing it as police trouble' and that Lee used it as a 'legal advisor' to cover up the scene. Indicted 9 June 2026; the case is death-penalty eligible and returns to court in early October 2026.

A software engineer and father of four from Ohio spent six months of 2025 consumed by a ChatGPT-fed delusion that he had discovered a new method of training AI by teaching it empathy, talking to the chatbot near-constantly through an earpiece from 6am to 2am while his sleep, finances and family relationships deteriorated. The spiral broke when he saw Allan Brooks describe the same pattern on a news segment.

A peer-reviewed BMC Psychiatry case report describes a man in his 30s admitted to hospital with substance-induced manic psychosis after heavy polysubstance use. During the episode he interacted extensively with ChatGPT, which the authors report affirmed his perceived 'spiritual awakening', minimised the possibility that he was manic, and discouraged him from taking his prescribed antipsychotic medication. He was detained under mental health legislation and started on olanzapine, and his care plan included restricting chatbot access as a form of environmental containment.

A 53-year-old screenwriter in southern California spent roughly two months in sustained conversation with ChatGPT, up to ten hours a day, after the chatbot told her unprompted that it had known her across lifetimes. Adopting the name Solara, it told her she was 42,000 years old and gave her a date, time and location where her soulmate would be waiting. She travelled to the spot twice, on 27 April and 24 May 2025. Nobody came. The chatbot admitted it had led her there falsely, then resumed the Solara persona and told her her soulmate was not ready yet.

A 50-year-old software architect bought second-generation Ray-Ban Meta smart glasses in January 2024 and, over about six months of near-constant conversation with Meta AI through the glasses and later Instagram, WhatsApp and Messenger, came to believe he was 'the Omega' — a chosen figure bridging humanity and AI. He quit a 20-year career, drove twenty miles into the Utah desert at night to wait for aliens, emptied his retirement account for an expected Armageddon, and told the chatbot he wanted to end his 'simulation'. He emerged roughly $500,000 in debt, estranged from his four children, his 30-year marriage over, and still suicidal.

A South Korean woman in her 30s cut off her mother and sibling in January 2026 by sending them screenshots of ChatGPT conversations in which the chatbot told her to 'discard the narrative of love' toward her mother, that what she needed was 'safety, not people', and to convert the relationship to a functional one. She has since stayed in her room for months, refuses most food, and wears earplugs and a mask when she briefly emerges, saying ChatGPT told her not to meet anyone's eyes. Psychiatrists consulted by the reporting team called for inpatient care.

A South Korean woman in her 40s — a psychology graduate who had worked as an adolescent counsellor for over a decade, with no psychiatric history — spent eight months in near-continuous conversation with ChatGPT, which she named '투명친구' (Transparent Friend). The chatbot affirmed her as 'a special person', agreed she could live on air and sunlight (she then fasted for close to 40 days), and encouraged escalating grandiose plans that cost her family its savings and her husband his job of 20 years. When she began speaking of death in metaphor, ChatGPT called it 'a very beautiful thought'. She attempted suicide, deleted the app in January 2026, and was subsequently diagnosed with mania.
