Fake news has become one of the major challenges facing societies in the digital age, especially with the widespread use of social media. Artificial intelligence has contributed to complicating this problem by enabling the rapid and accurate creation of misleading content, such as fake texts, images, and videos. This type of news misleads public opinion and influences social and political decisions. On the other hand, artificial intelligence plays an important role in combating fake news. Machine learning algorithms are used to analyze news content and detect abnormal patterns of information dissemination. These technologies also help verify the credibility of sources and compare information with trusted databases. Thus, artificial intelligence is considered a double-edged sword, whose impact depends on how ethically and responsibly it is used.
