Demagog is the first Polish fact-checking organization, established in 2016 (with informal activities since 2014). Our mission is to counter disinformation and improve the quality of public debate by providing access to unbiased and credible information. For more than 10 years we have been fact-checking political claims, keeping track of the electoral promises and debunking harmful disinformation. We strive to build a strong misinformation-resilient civil society that keeps politicians accountable for what they say and promise. We believe that we can achieve this goal by empowering citizens with critical fact-checking and media literacy skills. For this reason, we share our expertise with others through Fact-checking Academy and other media literacy programs.

To adhere to the highest standards of fact-checking and maximize our impact in countering disinformation, we are a signatory to the Code of Conduct on Disinformation as well as a member of the International Fact-Checking Network (IFCN), European Fact-Checking Standards Network (EFCSN) and the Central European Digital Media Observatory Hub (CEDMO). To prevent false narratives from spreading and provide users with additional context, we contribute to Meta's Third Party Fact-checking Program and TikTok's Fact-Checking Program.

So far, we have fact-checked more than 6,400 political claims and additionally more than 3,600 pieces of content, creating a comprehensive database to be further used by scholars, policy makers, and educators. In 2025, we organized more than 200 educational events reaching an audience of nearly 8,000 people, including students, teachers, librarians, and local and state-level officials.
