The purpose of this article is to assess and understand how artificial intelligence (AI) can influence the creation and dissemination of content for the purpose of disinformation, and how AI affects the distribution of such content. As the development and growth in popularity of content generation tools can be clearly seen, their use to create fake news is also steadily increasing. Professionally created content in both textual and graphical forms can be increasingly difficult for the reader to verify. The aim is also to identify strategies to counter disinformation created by artificial intelligence. The research problem focuses on verifying whether modern generative tools can be used to create and disseminate false information. The paper hypothesizes that AI-generated content can influence social misinformation, but that there are opportunities to mitigate the effects of this negative phenomenon. The research methodology was based on a critical analysis of the literature and experiments using popular AI tools to generate text and graphics. The results of the research confirmed that AI tools can be used to create fake content on a large scale. The use of AI tools not only facilitates the creation of professional content, but also allows it to be created very quickly, using little effort. Research has also shown that although censorship mechanisms are in place, there are methods to break through such safeguards. In the body of the article, the possibilities of bypassing the security mechanisms of AI tools are described. The conclusions of the research show the need to educate the public, which is a key element in the fight against disinformation. In addition, the article points out the importance of media responsibility in the process of verifying and exposing false content, which is an important element in countering disinformation.
