Articles and Episodes Rated

Since 2018, we’ve been on a mission to rate the news and make a positive impact on society. For too long, people have not had enough access to impartial ratings of the news. That’s why we’re here: to rate the news for reliability and bias so you don’t have to.

Ad Fontes is Latin for “to the source,” because at the heart of what Ad Fontes Media does is look at the source—analyze the very content itself—to rate it.

What We Do

We Rate the News

The information landscape is vast and noisy. We’re here to help you sort through it by rating sources for reliability and bias. Obviously, people have lots of different thoughts about how reliable and biased various news sources are, so we do everything we can to earn your trust. 

Analysts from a wide political spectrum

In order to mitigate bias, we create our news content ratings with a team of human analysts with political views from across the spectrum. They are trained to look at the content of the news and score it according to our methodology.

Public Benefit Corporation

Our mission is to rate all the news to positively transform society. Rating all the news is a big undertaking and requires scale, so we've set ourselves up to be a sustainable, growing business enterprise that is here for the long term.

Wide applications & distributed stakeholders

Our system of news content ratings can be used by all stakeholders in a healthy news media landscape, including consumers, educators, publishers, researchers, advertisers, and social media platforms.
