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 also records consequential decisions, claims and privacy harms involving AI. Each case needs a described connection between AI use and the harm, including private information recorded into or disclosed to an AI service. Each account is reviewed for publication; claims may remain uncorroborated or disputed. How we review and count cases

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.

1 Jul 2024 to 30 Sept 2025Event location unknownUnidentified voice-cloning tool

Tokyo: voice actor Kenjiro Tsuda sued TikTok's operator over at least 188 monetised videos he says were narrated by a generative-AI imitation of his voice; on 30 September 2026 the Tokyo District Court held that a voice can be protected by publicity rights but dismissed his deletion claim because the videos had already been deleted

Kenjiro Tsuda, a Japanese voice actor known for roles in Jujutsu Kaisen, sued the operator of TikTok in the Tokyo District Court in November 2025, seeking removal of videos he says use a generative-AI imitation of his voice without permission. According to his complaint, as reported by Jiji Press, Nikkei and the Asahi Shimbun, an account run by an unidentified person posted at least 188 short videos on urban legends, the occult and trivia between July 2024 and September 2025, narrated in a voice modelled on his; the account had about 210,000 followers, videos averaged 1.47 million views, and his side says the poster earned 500,000 to 750,000 yen a month from TikTok's view-based payments. TikTok's operator said the voice was a generic male voice that the poster said came from AI trained on a friend's voice. The poster deleted the account in May 2026. On 30 September 2026 the court held, as a general principle, that a person's voice is a symbol of personality like a likeness and that using a performer's voice without permission solely to exploit its power to attract customers infringes the right of publicity, the first such ruling in Japan. It dismissed the claim because the videos were already gone and TikTok's operator had no remaining duty to delete them, and it did not decide whether these videos infringed his rights (Nikkei; Asahi Shimbun; TV Asahi). His lawyer said they did not plan to appeal.

Zurich-Oerlikon, Switzerland: a student who researched killing methods, anatomy and where to find children with ChatGPT stabbed three five-year-olds walking to their daycare; sentenced on 18 September 2026 to 15 years for multiple attempted murder

At midday on 1 October 2024 a Chinese master's student, then 23, attacked a group of five-year-old kindergarten children walking with a daycare worker to their after-school Hort near Berninaplatz in Zurich-Oerlikon with a kitchen knife. Two boys suffered life-threatening neck and chest wounds (one had the jugular vein severed, one the pericardium and aorta cut); a third was wounded in the ear and the shoulder or lung. The daycare worker held the attacker's arms until he dropped the knife. The indictment and the court's oral reasoning, as reported by NZZ, Keystone-SDA/ATS and CH Media, describe weeks of preparation from summer 2024: he discussed ways of killing and their legal consequences with ChatGPT, studied anatomy, bought raw beef to practise stabbing, and used ChatGPT to find out where and when children could be encountered in Zurich. No source quotes the prompts or ChatGPT's replies. On 18 September 2026 the Zurich District Court convicted him of multiple attempted murder and imposed 15 years' imprisonment, treatment during custody, a 15-year expulsion from Switzerland and CHF 106,000 in moral damages to the three boys; it accepted that he was psychotic but found diminished, not absent, criminal responsibility. His lawyer announced an appeal. The parents of one boy described nightmares, self-blame and scars 23 months on.

AI involvement supported · Causal attribution unclear · 7 sources, 5 underlying accounts · Added 19/09/2026

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.
