1. Evernote Web Clipper

The first extension you can try to annotate a web page is Evernote Web Clipper. As you can guess, this extension is owned by Evernote, a well-known note-taking app so you can save your annotated web page directly to Evernote to make it easier to share with your friends online. Evernote Web Clipper enables you to highlight a certain text of a web page, annotate and add some symbols.

2. Hypothesis

With Evernote Web Clipper you can only add annotation by taking a screenshot of the current page. Hypothesis is different. You can add annotation directly on a web page without taking any screenshot.

The main purpose of Hypothesis — as described on its official site —  is to bring a new layer to the web. Hypothesis is a great tool if you are working on a paper and use internet as the reference. You can annotate or highlight a certain text and jump to main part of the web page you are refer to.

You need to create an account first before being able to use the extension. You will need the account to organize your annotated texts.
