FactCheck.org is a project of the Annenberg Public Policy Center of the University of Pennsylvania. It is a nonpartisan, nonprofit “consumer advocate” for voters. It aims to reduce the level of deception and confusion in U.S. politics by monitoring the factual accuracy of what is said by major U.S. political players in the form of TV ads, debates, speeches, interviews and news releases.
PolitiFact is a fact-checking website that rates the accuracy of claims by elected officials and others in American politics. PolitiFact is run by editors and reporters from the Tampa Bay Times. Staffers research statements and rate their accuracy on the Truth-O-Meter, from True to False. A search icon (not too evident) at the top of the entry page allows users to search the site.
The purpose of this website, and an accompanying column in the Sunday print edition of The Washington Post, is to “truth squad” the statements of political figures regarding issues of great importance, be they national, international or local.
Snopes, formerly known as the Urban Legends Reference Pages, is a fact-checking website.
NewsGuard is a browser extension created by NewsGuard Technologies. It rates news sources with either a green or red icon, which it calls "nutrition labels," indicating the news source's general trustworthiness and history of running stories labeled as fake news. Supported browsers include Google Chrome, Microsoft Edge, Firefox, and Safari. It is included by default in the mobile version of Edge, though users must enable it.
In January 2020, NewsGuard began notifying users that it would become a paid, member-supported browser extension in early 2020, while remaining free to libraries and educators who become part of a proposed partnership.
NewsGuard presents as a useful tool, albeit not free.
