AdDetector in action

Background

"Native advertising" is a type of advertising that presents ads as unbiased articles.

This technique is used by publications like the New York Times, Newsweek, The Atlantic, Buzzfeed, and others. Stories may be marked as sponsored, but these indicators are typically very subtle, leaving many readers unaware that the article is an ad.

AdDetector contains rules to identify small sponsored markings. In some cases, these indicators are not even visible normally and instead are hidden in the source code of the webpage.

Privacy

This extension requires permission to run on pages you visit, but your data is never used, stored, or transmitted. For those who wish to contribute or audit, AdDetector is open source.

Open Source

AdDetector is free to use and open source.
