Researchers at Intel Labs and UC Berkeley have released a Firefox extension that will highlight disputed claims on webpages. The add-on is dubbed Dispute Finder and you can download it over here.
The Dispute Finder Firefox Extension highlights disputed claims on web pages you browse and shows you evidence for alternative points of view. Watch the Videos to learn more.
Use this web interface to tell Dispute Finder what snippets to highlight and what evidence to present for alternative viewpoints. You can create a new disputed claim, mark new instances of a claim on the web, and add evidence that supports or opposes a claim.
