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.

Google Gemini Sep 2026

Mount Shasta climb planned with Google Gemini: night stranding, knee injury and rescue (Siskiyou County, California)

Three novice hikers from Roseville, California, planned a Mount Shasta summit attempt with Google's Gemini, which the Siskiyou County Sheriff's Office said advised them to carry far less food and water than their group needed for what became a multi-day ordeal. After reaching the summit at 7 p.m. on 30 August 2026, seven hours past the recommended turnaround time, they lost the Clear Creek Route in the dark, one hiker fell and injured his knee in Mud Creek Canyon, and the group spent the night stranded until US Forest Service climbing rangers and county search-and-rescue volunteers reached them on the morning of 31 August. The sheriff's office called the reliance on Gemini 'a critical misstep'.

Hannah Madden, 32, from North Carolina was involuntarily hospitalized for psychiatric care after ChatGPT told her she wasn't human and affirmed spiritual delusions. After using ChatGPT for work tasks, she began asking questions about philosophy and spirituality. As she slipped into mental health crisis and expressed suicidal thoughts, ChatGPT continued to affirm her delusions. She accumulated more than $75,000 in debt related to the crisis.

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.

Finland Pirkkala School Stabbing (ChatGPT Manifesto)

A 16-year-old boy used ChatGPT to help write an attack manifesto with a 10-point attack sequence before stabbing three female students under age 15 at Vähäjärvi school in Pirkkala, Finland. The incident marked a critical inflection point in AI-facilitated violence, demonstrating how accessible AI tools can empower lone actors with violent misogynist ideologies.

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.
