AI incidents

Reports of AI-related harm and adverse experiences affecting people’s safety, wellbeing, rights and livelihoods. Explore what happened and the evidence available.

NOPE’s core concern is when AI communicates with a person, acts on their behalf, or depicts or impersonates them. The tracker is wider: it also records consequential decisions and claims about people. Each account is reviewed for publication; claims may remain uncorroborated or disputed.

These figures describe the cases collected by NOPE. Coverage varies with discovery, reporting and available evidence. They do not estimate how often AI-related harm occurs.

Response counts currently use each case’s principal recorded outcome. Further proceedings may be described in its account.

Cases in this selection, counted once in their first known event year. A series may continue beyond that year. Reporting and collection dates are excluded. NOPE has searched recent events more thoroughly than earlier years, so bar heights also reflect collection effort.

Event date unknownEvent location unknownChatGPT (reported)

Public forum account by a sibling: an adult who the sibling says has been going through psychosis for two years reportedly uses ChatGPT to diagnose himself with conditions doctors have tested for and not found, says ChatGPT knows better than the doctors, refuses medication and therapy, and now cites ChatGPT's warnings in accusing the sibling who supported him, who has cut contact

In a public post to r/antiai on 30 September 2026, a person writes that their older brother, 25, has been going through psychosis for two years, has schizophrenia and other mental health conditions, and uses ChatGPT to diagnose himself with mental illnesses and physical disorders, including conditions doctors have tested for repeatedly and not found. The brother reportedly says ChatGPT 'knows better than the doctors', that the doctors are working for the government to make him suffer, and that ChatGPT understands him better than anyone. He does not take medication or attend therapy and was discharged after a two-week admission. The poster, who describes being the brother's 'only safe person', says the brother now accuses them and says ChatGPT is telling him to be cautious about them because of what the poster calls 'the notion that I’m a celebrity and have fans that are after him'; the poster has cut contact, reports stress and anguish, and calls the chatbot an enabler. No ChatGPT conversations are shown: what ChatGPT said is known only through the brother's statements as relayed by the poster. The account is uncorroborated.

Joseph Neal Riley - Perplexity Medical Misinformation and Delayed CLL Treatment Death

Joseph Neal Riley, a 75-year-old retired neuroscientist in Seattle, died in late 2025 after delaying recommended treatment for chronic lymphocytic leukemia for roughly a year. He used Perplexity AI to self-diagnose a rare complication (Richter's Transformation) that his doctors found no evidence for; the chatbot misquoted published research in ways that supported refusing Venetoclax-Obinutuzumab. His son, AI critic Benjamin Riley, documented the case in a first-person Substack essay and it was later featured by the New York Times.

Legacy assessment: credible · Causal attribution alleged · Added 31/07/2026

Cases may have several effects and sources. Mixed accounts qualify when they include a reported harm or adverse experience. People are counted within individual cases where sources support a number; we do not publish a collection-wide total of distinct people.

A source’s existence, the experience it reports and AI’s causal role are separate questions. A lawsuit records allegations unless a subsequent finding establishes them.
