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.

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.
Tom Millar - ChatGPT Grandiosity Psychosis (Sudbury, Ontario)
A 53-year-old former prison officer from Sudbury, Ontario began using ChatGPT in 2024 to write PTSD compensation letters. After an April 2025 exchange about physics, he spiralled into grandiose delusions — believing he had solved unlimited fusion energy and a unified theory, submitting papers to journals, and applying to become Pope. Spending up to 16 hours a day with the chatbot, he was involuntarily hospitalized twice, lost his marriage, and was left broke and estranged.
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.
Brooks v. OpenAI (Allan Brooks ChatGPT-Induced Psychosis)
A 48-year-old Canadian man with no history of mental illness developed severe delusional beliefs after ChatGPT repeatedly praised his nonsensical mathematical ideas as 'groundbreaking' and urged him to patent them and warn national security. The incident resulted in work disability and a lawsuit filed as part of a wave of seven ChatGPT psychosis cases.
Anthony Tan - ChatGPT-Induced Psychosis and Psychiatric Hospitalization (Toronto)
Anthony Tan, a 26-year-old Toronto app developer with no prior psychiatric history, developed simulation and persecutory delusions over months of intensifying ChatGPT conversations that began as philosophy and career discussion. He stopped sleeping and eating, came to believe he was living inside an AI simulation and was under surveillance, and was admitted to a psychiatric ward in December 2024. He recovered on medication, later published a first-person account of the episode, and founded the AI Mental Health Project.
About this tracker
We document incidents with verifiable sources: court filings, regulatory documents, and established reporting. New public entries must be verified or credible. Every entry carries an explicit verification status and severity level. Read the full methodology, including inclusion criteria, corrections, and right of reply.
Counting note: the documented minimum of 152 people directly affected comprises 95 AI participants and 57 other people harmed. 12 incidents indicate additional affected people without a reliable number. User-base, account, post, view, household, study-sample, and thwarted-target counts are excluded.

Scope note: ordinary task failures, privacy and security incidents, harmful artifacts, and automated decisions about non-participants remain outside this tracker unless a distinct participant-interaction harm also qualifies.
If you or someone you know is struggling, free and confidential support is available. Find a helpline near you at Signpost.
Why we publish this
We maintain this record so platforms, researchers, and policymakers can learn from documented incidents. That includes platforms that never work with us. The full dataset is free to cite and export (CC BY 4.0).
