Manually Declutter a Web Page

With so many people and companies trying to monetize the web, many pages we visit are overloaded with ads and clickbait links to drive traffic to other sites.

Our browser extension, Clip to DEVONthink, has an option to use a clutter-free layout. This does its best to extract the article from the current page. But what about pages you may have already clipped?
