The Evernote Web Clipper is a browser extension that allows users to instantly save articles or websites they're looking at to any notebook in Evernote for future reference, marking them up later. The clipper can be downloaded and installed on various browsers, including Chrome, Safari, Firefox, Opera, Internet Explorer, and Microsoft Edge. Users can choose how to clip their article, such as saving it as a simplified article or full page with comments and clutter included. Additionally, the Evernote Web Clipper makes it easy to send articles automatically through integrations with Zapier and other apps, allowing users to automate tasks and organize their online content in a personal database.
