Artificial intelligence, as the most powerful technological tool of the present century, has transcended the traditional boundaries of knowledge production and scientific research. This technology offers capabilities such as extraordinary data processing, automation of repetitive tasks, and assistance in complex analyses, providing an unprecedented opportunity to accelerate and deepen scientific discoveries. However, its application in writing scientific articles has brought significant achievements along with serious ethical, methodological, and legal challenges. Issues such as reduced transparency and research integrity, reinforcement of existing biases, violation of intellectual property rights, and reduction of researchers' analytical skills are examples of these difficulties. Faced with this complexity, the global community is striving to establish a balance between encouraging innovation and managing the risks associated with this technology by developing legal frameworks and regulations such as the European Union Artificial Intelligence Act, the Bletchley Declaration, the Committee On Publication Ethics, and the recommendations of the Organization for Economic Cooperation and Development. This article examines the pros and cons of artificial intelligence in scientific writing and analyzes relevant international regulations to present a path for the responsible, transparent, and effective use of this tool in advancing science. Iran's national guidelines for AI use in research emphasize transparency and full disclosure of its application.
