Artificial intelligence has started to become a part of scientific studies and may help researchers with a wide range of tasks. However, no scientific studies have been published on its ussefulness in writing cover letters for scientific articles. This study aimed to determine whether Generative Pre-Trained Transformer (GPT)-4 is as good as humans in writing cover letters for scientific papers.  \nMETHODS. In this randomised non-inferiority study, we included two parallel arms consisting of cover letters written by humans and by GPT-4 . Each arm had 18 cover letters, which were assessed by three different blinded assessors. The assessors completed a questionnaire in which they had to assess the cover letters with respect to impression, readability, criteria satisfaction, and degree of detail. Subsequently, we performed readability tests with Lix score and Flesch Kincaid grade level.  \nRESULTS. No significant or relevant difference was found on any parameter. A total of 61% of the blinded assessors guessed correctly as to whether the cover letter was written by GPT-4 or a human. GPT-4 had a higher score according to our objective readability tests. Nevertheless, it performed better than human writing on readability in the subjective assessments.  \nCONCLUSION. We found that GPT-4 was non-inferior at writing cover letters compared to humans. This may be used to streamline cover letters for researchers, providing an equal chance to all researchers for advancement to peer-review. FUNDING. This study received no financial support from external sources.  \nTRIAL REGISTRATION. This study was not registered before the study commenced.  \nArtificial intelligence (AI) has gained popularity in scientific research, aiding researchers with a wide range of tasks [1] . An example is the Chat Generative Pre-Trained Transformer (ChatGPT) series by OpenAI, which included GPT-3 .5 in November 2022 and the subscription-based GPT-4 in March 2023 [2] . Researchers have already used ChatGPT to write essays, summarise literature, draft and improve papers, and write computer code [3, 4] . Nevertheless, no studies have been published on the capabilities of GPT-4 in writing cover letters for scientific journal submissions. In the submission process of an article, a cover letter promotes the manuscript and is often mandatory [5] . The cover letter provides an opportunity to highlight the importance of the study to journal editors. It should include key elements such as the manuscript title, journal name, a concise study description, its importance and its appeal to readers. Moreover, the cover letter should address matters such asthe originality of the manuscript, clarify any conflicts of interest and provide contact information [5] . Researchers must invest time in preparing a well-written cover letter as an effective cover letter may tip the balance between immediate rejection or peer review. If GPT-4 may help with this process, researchers would be able to streamline their workflows and optimise their use of time.  \nDANISH MEDICAL JOURNAL  \nThis produced the rationale of a non-inferiority study investigating whether GPT-4 may write cover letters that are just as good as human-written cover letters. Thus, the aim of this non-inferiority randomised study was to determine whether ChatGPT-4 is as good as humans in writing cover letters in terms of impression, readability, criteria satisfaction, degree of detail and preference.  \nMETHODS  \nThis randomised, blinded non-inferiority study was reported according to the Consolidated Standards of Reporting Trials extension for non-in","cbCaick0veIFWhHW","https://ap.wps.com/l/cbCaick0veIFWhHW","pdf",350707,8,"English","# Abstract\n## Introduction\n## Methods\n## Results\n## Conclusion\n## Funding and trial registration","[{\"question\":\"What was the purpose of the study?\",\"answer\":\"The study aimed to determine whether GPT-4 is as good as humans at writing cover letters for scientific papers.\"},{\"question\":\"How were the cover letters evaluated?\",\"answer\":\"Cover letters written by humans and GPT-4 were assessed by blinded assessors using impressions, readability, criteria satisfaction, and degree of detail, followed by objective readability tests (Lix and Flesch Kincaid).\"},{\"question\":\"What were the main findings?\",\"answer\":\"No significant or relevant differences were found across evaluated parameters, and GPT-4 demonstrated non-inferiority for cover letter writing compared with humans.\"}]","A comparison of cover letters written by ChatGPT-4 or humans | PDF"]
