"The tagline for this helpful extension is that it is "teaching computers how to read and understand language." As users browse the Internet, this extension learns more about what they like to read and recommends more articles that fit the profile. This is based on an Interest Graph, or "a list of topics and concepts derived from what you've been looking at on the internet." When Gravity Highlighter finds a story you might like, it adds it to your newsfeed, which can be further refined by giving suggestions a thumbs-up or thumbs-down. This version is compatible with all operating systems running Chrome."
