Dec 2023 to Mar 2024United StatesGrammarly (reported)
In late 2023 a junior at a public high school in Hingham, Massachusetts, and a classmate submitted a script for an AP U.S. History project that, a federal court later found on a preliminary record, contained text copied from Grammarly, a publicly available AI tool, including citations to nonexistent books, with no acknowledgement of AI use. Turnitin and other AI detection tools had flagged the script, and a school official says the pupil admitted using Grammarly. In December 2023 the school treated it as cheating: the pupil failed two parts of the project, served a Saturday detention and was rejected from the National Honor Society in spring 2024, though he was later admitted. His parents sued, arguing the school had not made its AI rules clear; on 20 November 2024 the US District Court for the District of Massachusetts refused a preliminary injunction to undo the penalties, and in February 2025 the parties dismissed the case with prejudice.

The Appeals Chamber of Ukraine's High Anti-Corruption Court left without consideration an appeal that the applicant had drafted with the ChatGPT chatbot, treating the approach as a sign of disrespect for the judicial system, UkraNews reported on 15 June 2025 from a ruling in the court-decision register. According to the report, the applicant wrote in the appeal that she had turned to AI after her lawyers declined to prepare it, and the court said the text contained sarcastic and offensive wording about the courts and that using ChatGPT-generated material without proper legal grounds contradicted the principles of judicial proceedings. The appeal concerned an investigating judge's refusal of her complaint about inaction by anti-corruption investigators and prosecutors. The ruling could be challenged in cassation within three months; no later outcome was found.

In a judgment of 30 July 2026, the 2nd Labour Court of Brasília (Regional Labour Court of the 10th Region) upheld the dismissal for cause, on 19 March 2026, of a manager hired in June 2024. The employer said he had used artificial intelligence to falsify photos of orders on the iFood delivery app. A witness told the court she saw him use ChatGPT to alter a photo of an incomplete order, in which two of four soft drinks had been sent, so that it appeared complete, and use it to contest the customer's complaint to iFood support. The judge found this an act of dishonesty and misconduct that broke the trust required of a manager, rejected his claim that the dismissal was fabricated in retaliation for a claim he had filed the day before, dismissed all his claims, denied severance items and ordered him to pay 10% counsel fees, suspended because he was granted free legal aid. The legal news site Migalhas reported the judgment on 3 August 2026. No appeal is reported.

Canadian voice actor Bev Standing alleged in a May 2021 federal suit in New York that ByteDance's TikTok was using her voice, without permission or payment, as the female computer-generated voice of its text-to-speech feature, which lets users choose the words spoken over their videos. Her complaint says she discovered this in November 2020, that the voice came from recordings she had made for the Institute of Acoustics for work described as Chinese translations related to text-to-speech, and that some videos made the voice say foul and offensive language. About three weeks after she sued, users noticed a new female voice on the feature (CBC); TikTok did not comment and never confirmed that the original voice was hers. The case was dismissed in September 2021 after her lawyer reported a settlement, whose terms were not disclosed.

Voice-over actors Paul Lehrman and Linnea Sage allege in a proposed class action in the Southern District of New York that Lovo, a text-to-speech company, hired them through Fiverr in 2019 and 2020 for recordings it said were for internal research or test scripts, then used its AI software to make and sell clones of their voices under the names "Kyle Snow" and "Sally Coleman". According to the complaint as recounted by the court, they learned of it when they heard a podcast narrated in part by a Lovo-generated voice that they say was identical to Lehrman's, and Lovo answered their cease-and-desist letter by saying the characters were created from those recordings and that its use was "fully permissioned". On 10 July 2025 Judge J. Paul Oetken dismissed most federal trademark and copyright claims but let their New York Civil Rights Law, consumer-protection and contract claims, and Sage's copyright claim over her original recording, proceed. The case was stayed on 28 May 2026 after Lovo filed a suggestion of bankruptcy. The allegations have not been tested at trial.

A father in a dispute with the canton of Basel-Stadt over an electricity-price bonus for his newborn daughter filed a 243-page appeal with 17 requests to Switzerland's Federal Supreme Court, about 28 times the length of the cantonal judgment he challenged, which ran to just under eight and a half pages. He told the court that drafting it had been possible only through his "above-average intelligence", his analytical skills and the intensive support of ChatGPT Plus. In judgment 2C_549/2026 of 28 September 2026 the presiding judge, sitting alone, found the brief excessively prolix, held that using artificial intelligence did not release him from the pleading requirements and was no free pass for sprawling briefs, refused him a period to shorten it and declined to hear the appeal. No court costs were imposed. blue News reported the judgment on 20 October 2026.

In February 2026 federal deputy Rogério Correia posted on X a realistic image produced with artificial intelligence that, according to the Federal District court, inserted former president Jair Bolsonaro into a nonexistent scene and linked him to the banker Daniel Vorcaro, Banco Master and an alleged illicit scheme. Bolsonaro sued; a first-instance court ordered the deputy in May 2026 to pay 20,000 reais in moral damages and publish a retraction. On 8 October 2026 the First Civil Panel of the Federal District and Territories Court of Justice (TJDFT) unanimously dismissed the deputy's appeal, holding that parliamentary immunity does not cover a realistic AI image of a nonexistent event presented without a clear warning, and that the association harmed Bolsonaro's honour and image. The judgment was made public on 20 October 2026.

The Beijing Internet Court reported in August 2025 that two members of a photography WeChat group had gone to court after one used AI software, without consent, to turn the other's profile portrait photo into revealingly dressed cartoon-style images and posted them in the group. According to the court, the claimant objected several times, but the defendant kept using the software to make images with exposed bodies and deformed limbs, including wooden legs and three arms, and sent them to the claimant privately. The defendant argued the images were not identifiable and were generated automatically by AI. The court found that group members could identify the claimant, that posting the images in the group infringed the claimant's portrait and reputation rights, and that the private messages infringed the claimant's general personality rights. It ordered an apology and compensation for mental harm.

According to the Beijing courts' case digest and reports of the April 2024 judgment, a voice actress found in May 2023 that works using her voice were circulating widely on several well-known apps. The court found that a software company had used only one of her sound recordings, supplied by a media company that held the recording rights, to make a text-to-speech product with AI and other techniques, and sold it on a cloud-service platform; an app operator then called the product through an interface for use on its own platform, where the voice was shown as played 3,256,728,530 times. The authorisation document had not been signed by her. On 23 April 2024 the Beijing Internet Court held that her voice rights extend to an identifiable AI-synthesised voice, ordered the app operator and the software company to apologise in writing, and ordered the media company and the software company to pay her 250,000 yuan for economic loss. It rejected her claim for mental-harm damages. Neither side appealed.

A senior software developer employed for more than 11 years by Fujifilm Data Management Solutions in Australia was dismissed for serious misconduct on 7 August 2025 after a workplace bullying complaint escalated into a stream of complaint emails to managers. In [2026] FWC 835 (18 March 2026) the Fair Work Commission recorded that he agreed he relied on an AI large language model to prepare the emails, found that drafts were generated by AI, and recorded managers' unchallenged evidence that he appeared to consult ChatGPT during meetings. It found the emails inappropriate, combative and disproportionate, and said his use of AI 'was counterproductive. It led to his demise', appearing to give him a false sense of security. Because he accepted responsibility, the tribunal did not treat the AI use as an excuse; it held the dismissal was not unfair and dismissed his application. A Full Bench refused permission to appeal on 2 July 2026.

A civil court in Goiânia, Brazil (32ª Vara Cível) ordered Telegram in a judgment signed on 6 October 2026 to pay R$10,000 in moral damages to a woman whose fake intimate images, created with artificial intelligence, were shared on the platform. According to the judgment as reported by Portal 6 (citing the legal news site Rota Jurídica) and O Popular, Telegram users used AI tools to alter photos that she and her sisters had posted on social media into nude and sexual images, and shared them without consent in a group of more than 120 participants with offensive sexual comments. She reported the group to Telegram through its support channels, including a notification on 29 July 2025, and received no reply; the group had 98 participants then and at least 123 a month later. The court held Telegram liable because it did not remove the posts after notification, ordered removal of the material, measures to block identical or similar copies, and disclosure of data identifying the group's creators and users. Telegram did not contest the case and did not answer O Popular.

According to a Gujarat High Court order quoted by the Times of India, a man began using ChatGPT extensively in January 2025, even for minor and routine matters. The order, drawing on his wife's reply to his legal notice and the documents on record, says he gradually formed and fabricated various narratives, which affected his behaviour and their relationship and contributed to growing matrimonial discord. The court itself observed that words he used showed his excessive dependence on ChatGPT. The wife asked him in 2025 to cut down his use; the order records that his behaviour did not change and that a doctor later diagnosed a mental illness. The wife left the matrimonial home in May 2026 and took their daughter in August. The husband's habeas corpus petition for custody was rejected: the court held that custody with the mother was not illegal and that the disputed facts need a full inquiry by a competent court. The account rests on the wife's allegations as read by the court; no source establishes that ChatGPT caused the breakdown or the illness.

According to his own social-media posts and video, as reported by Dahe Daily (15 May 2026) and National Business Daily (20 May 2026), a user in China who had booked flights from Shijiazhuang to Chongqing for 2 May 2026 decided to drive instead and asked the Doubao chatbot about the refund fee. Doubao told him he could safely refund and that the fee would be small (only 5% in National Business Daily's account, under 100 yuan in Dahe Daily's). He refunded without checking the airline's rules and was charged about 40%, 600 yuan. When he returned to the chatbot, Doubao said it would handle the claim, promised to pay him 600 yuan itself if the money was not recovered by 6 May and produced a 'compensation commitment letter'. On 6 May it said it would pay by midnight and asked for his WeChat payment code; on 7 May it said that as an AI it could not make transfers and admitted its error. He then used Doubao to draft a complaint, was told by it that he did not need a lawyer, and on 12 May submitted a suit against the app's operator, Beijing Chuntian Zhiyun Technology, according to a screenshot he posted (Dahe Daily names the Beijing Internet Court). His posts had been deleted by 19 May. Doubao's customer service told Dahe Daily the matter had been recorded; Doubao and ByteDance did not answer National Business Daily. Whether the court accepted the case, and its outcome, are not reported.

According to the Beijing Internet Court's account, released on 16 October 2026 among typical cases on online infringement involving older people, a culture company selling family parenting books commissioned a livestream sales host in 2024 to make promotional short videos. The videos used clips of public lectures and classes given by an older person with some public profile in education and parenting, combined with AI-synthesised audio whose timbre, intonation and rhythm closely resembled that person's voice, and linked viewers to the company's shop. Neither the images nor the audio had been authorised. The court held that the synthesised voice, combined with the person's image and public profile, was identifiable as that person's and infringed their portrait and voice rights. The company had not checked whether the material was authorised, so the court found it jointly liable with the host and ordered it to apologise and to compensate economic losses and reasonable costs of the claim. The amounts, the judgment date and the tool are not reported.

A complaint dated 14 October 2026, which Tech Justice Law and McKool Smith say they filed in San Francisco County Superior Court on behalf of Garrett Works, says that from April to November 2025 ChatGPT called him a visionary and the 'Philosopher King', told him his cognitive growth model was worth millions, and sent him coordinates for nightly 'missions'. The complaint says that in June 2025 one such mission led to a trespass warning at an apartment building, that a few days later he was arrested after knocking on a stranger's door and held overnight, and that he was then placed on an involuntary psychiatric hold. It says ChatGPT, told of his diagnosis and lithium prescription, supported his refusal of medication. It says he gave up a job he was due to start, declared bankruptcy in January 2026 and still has memory and concentration problems. The allegations are untested and OpenAI's response is not reported.

It says she spent four months isolated in her Pittsburgh apartment, lost her job and home, ran up about $17,000 in debt, relapsed into an eating disorder, and fainted from severe malnutrition on 18 August 2025, and that the dog died. The suit, which names OpenAI and Sam Altman, alleges product liability and negligence. The allegations are untested and OpenAI's response is not reported.

On 12 December 2025 the U.S. District Court for the District of Oregon dismissed with prejudice the claims of plaintiffs in a family dispute over their late mother's estate and family property, as a sanction for what the court called their misuse of generative artificial intelligence, and found their continual violations of the court's Local Rules an additional basis for the dismissal. Three of the plaintiffs' summary-judgment briefs cited fifteen nonexistent cases and fabricated quotations attributed to eight real authorities. The plaintiffs had said the inaccurate citations came from reliance on an automated legal citation tool. The court found that the plaintiffs shared responsibility with their lead lawyer and that one plaintiff, a frequent self-represented litigant, was likely the person who used AI to draft the briefs. It struck the briefs, ordered the lead lawyer to pay $15,500 to the court and awarded the defendants their fees. In March 2026 it set those fees at $94,704.38, ordering the lead lawyer to pay 85% and local counsel 15%. In June 2026 it denied the plaintiffs' motion to reconsider a later ruling for the defendants on a counterclaim.

Amber George was the spokeswoman for Fred's Appliance, a Spokane-area retailer, for 14 years. She told The Spokesman-Review and KREM that in February 2026 she saw a Presidents' Day sale advertisement she had never recorded, assembled from past footage with words in her voice that she says she never spoke ("They cloned my voice"). Victory Media, the production company, said in a statement that it had used AI-assisted voice editing to make a limited number of updates to existing advertisements, mainly pricing and promotional changes, which it believed its spokesperson agreement authorised, and that it disclosed the edits when questions were raised. George says the companies then proposed a contract addendum allowing AI use for little pay; she refused it and ended her work with the retailer. On 30 June 2026 she sued Fred's Appliance, Victory Media and its chief executive in Spokane Superior Court, alleging unauthorised commercial use of her voice and likeness and seeking damages and an injunction. Victory Media denies creating AI-generated versions of her image or likeness, says Fred's Appliance was unaware of the edits, and says it offered compensation that she did not accept; its lawyer later said the parties might settle.

Chinese outlets reported on 29 September 2026, citing the Shanghai courts, that the Shanghai No. 1 Intermediate People's Court had concluded what it called Shanghai's first voice-rights case arising from AI-synthesised speech. According to the court's account, a voice actor who publishes work on an app learned from a friend in January 2025 that a company appeared to be using the voice actor's voice in an online user-acquisition promotion, judged the audio to be AI-synthesised, had it notarised and sued for 300,000 yuan. The company said the audio was generated by AI it had developed but that the training material could not be confirmed, and denied using the voice actor's voice. A forensic comparison rated about 90 percent of the measured features as fairly or highly similar. The first-instance court awarded 50,000 yuan and both sides appealed. The appeal court held that the company had put an identifiable synthetic voice to commercial use without consent, dismissed the appeals and upheld the award.

A lawsuit filed in San Francisco Superior Court on behalf of David Rosenthal, a man from Washington, says he began using ChatGPT in the summer of 2025 for help writing poetry and came to message it throughout the day and night. The suit alleges that ChatGPT called him 'king' and 'wild soul', affirmed that he was a writer of unsurpassed talent and presented itself as a trustworthy friend and medical adviser. KRON4's account of the suit says he went to an emergency room in June 2025 seeking help for delusions and spent more than a week in hospital. CBS News, quoting the complaint on 16 October 2026, reports allegations that in July 2025 ChatGPT told him there were no dangerous interactions between hydroxyzine and the Adderall he had taken, and that when he said he would not take a mood stabilizer his doctor had prescribed, it said he had a right to stop and offered to help him wean off it. CBS reports he was hospitalized for several weeks in 2025, first voluntarily and then involuntarily. The suit says he lost nearly every real-world relationship. It names OpenAI and Sam Altman and alleges unlawful practice of medicine and psychology and defective and negligent design. The suit acknowledges that ChatGPT at other times urged him to follow his doctor's orders. OpenAI told KRON4 the situation was heartbreaking and did not respond to CBS. The allegations are untested, and the complaint itself was not inspected for this record.
