Hoaxy® visualizes the spread of claims and related fact-checking online. A claim may be a fake news article, hoax, rumor, conspiracy theory, satire, or even an accurate report. Anyone can use Hoaxy® to explore how claims spread across social media. You can select any matching fact-checking articles to observe how those spread as well.

Hoaxy® is one of many tools in Indiana University's Observatory on Social Media (OSoMe).

 IUNI's Github page allows users to download Hoaxy's open source code. IUNI also hosts and maintains Hoaxy. Chengcheng Shao, a visiting scholar from the National University of Defense Technology, served as the main developer on the tool.
