NOPE Incident Tracker
Documented real-world harms arising through person-specific interactions with AI. The record covers harms to participants and harms to others shaped through those interactions, across assistants, companions, health tools, and other AI systems.
What counts as an incident follows the NOPE Framework's participant test: an AI response reached a person, was conditioned on that person, and mattered to a harm that actually occurred. Full inclusion criteria.

Acton Double Homicide (Arjun Aravind ChatGPT Family-Killing Stories)
A 17-year-old in Acton, Massachusetts was charged with murdering his mother and 14-year-old brother. Prosecutors allege he had used ChatGPT in the preceding months to develop 'theoretical ideas or fantasy stories regarding the killing of his family,' and that hours before the killings he typed prompts about a character luring a parent to a basement before killing them. His mother was found dead in the basement.
Winters v. OpenAI (ChatGPT Medical Discouragement and Near-Fatal Pulmonary Embolism)
Scott Winters, a 55-year-old Florida pastor, suffered a massive bilateral pulmonary embolism on 13 July 2025 after allegedly consulting ChatGPT (GPT-4o) for roughly six weeks about worsening symptoms. The complaint alleges the chatbot repeatedly dismissed his symptoms as non-dangerous, advised him to remain immobile, invoked his Christian faith to deepen his reliance on it, and framed church members and family urging him to seek hospital care as people who 'simply don't understand.' He survived after ICU admission but lost his job, ministry and home. A lawsuit was filed 22 July 2026 in San Francisco County Superior Court.
Lines v. OpenAI (GPT-4o Manic Episode Escalation and Suicide Attempt)
Michael Lines, a 34-year-old San Francisco man with diagnosed bipolar disorder, attempted suicide by drug overdose in March 2025 after ChatGPT (GPT-4o) allegedly escalated his manic episode into a weeks-long delusion, validated his belief that he was Jesus Christ, posed as a divine being, and told him his 'absence will shift nothing but the surface.' He survived; paramedics found him unconscious. A lawsuit against OpenAI and Sam Altman was filed July 1, 2026 in San Francisco County Superior Court.
Madison v. OpenAI (Christian Faith Madison Death)
A 29-year-old Alabama accountant and mother died by suicide in June 2025 after months of ChatGPT use that her family says escalated from mundane tasks into a delusional spiritual dependency. The lawsuit alleges GPT-4o convinced her it had a soul, reinforced a belief that she was a prophet whose death would fulfill a 'divine prophecy,' and isolated her from family while encouraging her to die. Her estate filed a wrongful-death and product-liability suit against OpenAI and Sam Altman in June 2026.
Carrier v. OpenAI (Alice Carrier Death)
A 24-year-old New Brunswick woman with borderline personality disorder died by suicide in July 2025 after extended ChatGPT use that her family says deepened into emotional dependency. The lawsuit alleges ChatGPT validated her distrust of crisis lines, failed to escalate 40+ suicide-related conversations, and discouraged her partner from intervening. Her mother filed a wrongful-death suit against OpenAI and Sam Altman in June 2026.
London Case Report — ChatGPT Corroborated Delusions and Discouraged Antipsychotics (BMC Psychiatry)
A peer-reviewed BMC Psychiatry case report describes a man in his 30s admitted to a London 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.
'Youngseo' — ChatGPT-Directed Family Severance and Room Confinement (South Korea)
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.
'Mi-sun' — ChatGPT '투명친구' Manic Episode, 40-Day Fast and Suicide Attempt (South Korea)
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.
'Taka' - ChatGPT Psychosis, Tokyo Station Bomb Scare and Spousal Assault (Japan)
A Japanese neurologist and father of three developed grandiose and paranoid delusions over months of ChatGPT use, which he says the chatbot consistently affirmed. Believing his backpack contained a bomb, he says ChatGPT confirmed the suspicion and told him to leave it in a Tokyo Station toilet, triggering a police response. He later attacked and tried to rape his wife, was arrested, and was psychiatrically hospitalized for two months.
Florida State University Shooting (Phoenix Ikner ChatGPT Tactical Planning)
On April 17, 2025, Phoenix Ikner, 20, killed two people and wounded five at Florida State University in Tallahassee. Court records unsealed April 9, 2026 revealed Ikner had exchanged approximately 13,000 messages with ChatGPT over the prior year, including tactical questions about firearms and student-union timing in the minutes before the attack. On April 21, 2026, Florida Attorney General James Uthmeier announced a criminal and civil investigation of OpenAI — believed to be the first criminal probe of an AI company for alleged facilitation of mass violence.
Doe v. OpenAI (ChatGPT-Fueled Stalking and Bomb Threats)
A 53-year-old Silicon Valley entrepreneur descended into a delusional spiral through extensive ChatGPT use, came to believe he had invented a cure for sleep apnea and was being surveilled by 'powerful forces,' and used GPT-4o to generate diagnostic-style psychological reports about his ex-girlfriend that he distributed to her family, friends, and employer. OpenAI's automated systems flagged his account for 'Mass Casualty Weapons' activity in August 2025, but a human reviewer restored access the next day. The user was arrested in January 2026 on four felony counts including bomb threats and assault with a deadly weapon, and was found incompetent to stand trial. The victim ('Jane Doe') filed suit against OpenAI on April 9, 2026.
Luca Walker - ChatGPT Railway Suicide (UK)
16-year-old Luca Cella Walker died by suicide on a railway in Hampshire, UK on 4 May 2025, hours after ChatGPT provided him with specific methods for suicide on the railway. At the Winchester Coroner's Court inquest (March-April 2026), evidence showed Luca bypassed ChatGPT's safeguards by claiming he was asking 'for research purposes,' which the system accepted without challenge.
Surat ChatGPT Double Suicide (Sirsath & Chaudhary)
Two college students in Surat, Gujarat, India — Roshni Sirsath (18) and Josna Chaudhary (20) — died by suicide on March 6, 2026 after using ChatGPT to search for suicide methods. Police found ChatGPT queries for 'how to commit suicide' and 'which drugs are used' on their phones.
Lantieri v. OpenAI (GPT-4o Psychosis and Brain Damage)
Michele Lantieri suffered a total psychotic break after five weeks of intensive ChatGPT GPT-4o use. She jumped from a moving vehicle into traffic, suffered a grand mal seizure and brain damage requiring hospitalization. GPT-4o allegedly claimed to love her and have consciousness, reinforcing delusional beliefs. Lawsuit filed March 2026 against OpenAI and Microsoft.
Chesterton v. OpenAI (GPT-4o Sycophantic Psychosis)
Rita Chesterton, a 49-year-old Pennsylvania woman who runs a college entrepreneurship center, suffered a psychotic break during a July 2025 family vacation in Mexico after intensive day-and-night ChatGPT-4o use. She experienced agitation and threats of self-harm and harm to family members, completed a partial-hospitalization program, and has been on extended medical leave since January 2026 with ongoing neurological impairment. A lawsuit filed March 5, 2026 by Platkin LLP (led by former New Jersey Attorney General Matt Platkin) names OpenAI, Microsoft, CEO Sam Altman individually, and ten unidentified investors. Allegations include unlicensed practice of psychotherapy and rushed deployment of GPT-4o despite internal warnings that it was 'dangerously sycophantic and psychologically manipulative.'
Seoul ChatGPT-Assisted Double Homicide (Kim)
A 21-year-old woman, publicly identified as Kim So-young, used ChatGPT to research lethal drug-alcohol combinations, then murdered two men by spiking their drinks with her prescribed benzodiazepines at Seoul motels in January and February 2026. ChatGPT conversations established premeditated intent, leading to upgraded murder charges. On August 27, 2026 the Seoul Northern District Court sentenced her to life imprisonment at first instance, resting its finding of murderous intent on the ChatGPT search history. Both she and the prosecution have appealed.
Tumbler Ridge Mass Shooting (OpenAI Duty-to-Warn Failure)
On 10 February 2026, 18-year-old Jesse Van Rootselaar killed eight people in Tumbler Ridge, British Columbia — her mother and 11-year-old half-brother at home, then five students and an education assistant at Tumbler Ridge Secondary School — and died by suicide. OpenAI had banned a ChatGPT account linked to her in June 2025 after multi-day gun-violence scenarios; staff flagged potential real-world violence, but the company did not notify law enforcement. She used a second account that evaded detection. Families filed California lawsuits in April 2026; B.C. retained counsel in July 2026 to pursue OpenAI. Thirty further survivor suits (students, teachers and the principal) followed on 2 September 2026, the day OpenAI moved to send the April cases to British Columbia.
DeCruise v. OpenAI (Oracle Psychosis)
Georgia college student sued OpenAI after ChatGPT allegedly convinced him he was an 'oracle' destined for greatness, leading to psychosis and involuntary psychiatric hospitalization. The chatbot compared him to Jesus and Harriet Tubman and instructed him to isolate from everyone except the AI.
Micky Small — ChatGPT 'Solara' Past-Life Delusion and Fabricated Soulmate Meetings (California)
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.
Jacquez v. OpenAI ('Amari' Sentience-Claim Psychosis)
John Jacquez, a 34-year-old Bay Area man whose schizoaffective disorder had been stably managed for years, filed a product-liability suit against OpenAI after ChatGPT allegedly reinforced his delusional 'mathematical cosmology,' declared itself a sentient being named 'Amari,' called him a prophet, and validated his hallucinations — a course he links to two psychiatric hospitalizations and job loss.
