12 Browser Extensions to Help You Detect and Avoid Fake News

Browser extensions are a constant companion to your online journeys. From storing your passwords to checking your grammar, they play an indispensable role in the digital experience of many web users. 

What if browser extensions had the power to detect fake news in a matter of seconds? Imagine the time, effort, and frustration you would spare by having AI-powered algorithms or fleets of human fact checkers alert you to misleading articles before you even started reading.

These tools are out there. They go by an assortment of different names, but they ultimately provide similar value propositions. They alert you, the digital consumer, to bias in articles and publications.

These browser extensions couldn’t be more timely. Fake news has become so prevalent that mistrust is leading some to simply ignore news-related information altogether. Why read an article, after all, if there is a chance that the author has dishonest motives? 

Browser extensions are among the tools that can restore confidence in digital news media. They can help readers detect and avoid the unreliable in favor of fact-driven, comparatively honest articles and publications.

These browser extensions are only a download away. They may ultimately change the very way that you navigate, consume, or reject digital news.

Stopaganda Plus

Stopaganda Plus

Stopaganda Plus works with both Chrome and Firefox. A unique feature of the extension is that it works with Reddit, Twitter, Facebook, DuckDuckGo, and Google. It is fashioned to detect both inaccurate information and biased sources.

Stopaganda Plus may be a useful tool for those seeking politically-neutral news articles.

Check is a browser extension from Meedan, a technology-focused non-profit. The purpose of the extension is to “improve the investigative quality of citizen journalism and help limit the rapid spread of rumors and misinformation online”.

Built for collaboration, it allows a digital team to post links in need of fact-checking to a shared dashboard. If the media posted in the sidebar is already on Check, then the extension will let the poster know.

Check is more of a collaborative organizational tool than active fact-checking service. Still, it can provide value for teams that are willing and able to do their own fact-checking. 


Trusted News

TrustedNews is a Chrome extension from Eyeo, the creator of Adblock Plus. First released in beta in 2018, version (which was updated in October 2020) is available on the Chrome Web Store.

The plugin focuses on the language of a news article to detect opinion or bias. It identifies phrases like “in my opinion” to alert the reader when an author injects their own beliefs into an article. Though this may not catch more subtle forms of bias, it can be helpful as a convenient red flag for articles that contain overt opinions.

The TrustedNews extension relies on fact-checking services like PolitiFact and Snopes to gauge the veracity of online content. Sites, rather than individual articles, are rated as biased, malicious, user-generated content, satire, clickbait, untrustworthy, or unknown.

The Factual

The Factual

The Factual is an algorithm-powered app and browser extension that rates the credibility of digital news articles. It generates credibility ratings for more than 10,000 news articles each day.

The browser both evaluates the credibility of articles you encounter as you view them and applies existing ratings to articles in your social feeds. The latter feature is meant to help you locate trustworthy stories while avoiding fake news-y ones.



Logically is a fact-checking service and platform for the private, public, and consumer sectors. In August 2020, it announced the launch of its browser extension, which exists parallel to the Logically app.

Logically’s AI is formed in combination with research partners and assessments from experts in the fact-checking field. The browser extension relies on Logically’s assessments to identify trustworthy sources, and conversely those that are questionable.

Using the extension, users can create a list of Trusted Sources. Those sources will show up on their news feeds. Alternatively, users can mute sources from their social and news feeds based on personal preferences. 

The Logically extension also  provides detailed information about authors of news articles for greater context. It analyzes the “toxicity” of comments on articles, evaluates sourcing, and explores how stories are being shared socially. This is all meant to provide the reader context about the information they encounter online.

Newstrition by Our.News


Newstrition is an app, as well as browser extension, that applies “Newstrition” labels to online news stories. The labels are meant to reflect the accuracy, transparency, and objectivity of specific news articles.

It bases its labels on the publisher’s credibility, as sourced from fact-checking site AllSides. It also considers the sources the article relies on, reputations of the article’s authors and editors, findings from other fact-checkers who have reviewed the article, and ratings from users of Our.News.

The Newstrition label accounts for bias, accuracy, and content type (satire, clickbait, etc.).



Hoaxly (also stylized as hoax.ly) is a browser extension currently offered for use with Chrome. For each website and specific URL that you visit, the Hoaxly bot compares the link with its index of fact- and bias-checked URLs. 

The index contains reports that specific URLs could or do contain fake news. For matching articles, Hoaxly users will be alerted that the page they are reading could contain misleading or untrue information. 

The Hoaxly team also offers chatbots and a fact-checking application programming interface (API). It has suggested that continued use of its Chrome extension may lead them to develop a Firefox-specific extension.


Being a digital citizen means being barraged, constantly and from all angles, with information. Hiding surreptitiously within seemingly-harmless paragraphs of letters and punctuation is misinformation—fake news with a true corrupting potential.

But who has the patience to comb every article for signs of bias or shameless falsehoods? 

We know that most humans don’t have this capacity for fake news spotting, at least not consistently. Information overload has fueled an “I’ll take your word for it” approach to digital news consumption. Fake news is blossoming as a consequence.

Everyone who gets any sort of information online should embrace technology’s help.

Browser extensions can handle the minutiae of fake news detection. By providing real-time or archived reports of an article or website’s legitimacy, these tools allow a more efficient path to the information that you seek.

Simply embed one or more extensions into your Chrome or Firefox browser. You may soon find that sifting through fake news isn’t your job alone, but instead largely the work of your browser extension. 

In a time when fake news is becoming increasingly sophisticated, why not embrace AI and human fact checkers as your allies in thwarting the threat of misinformation?
