I have a habit of writing in books while reading them with a pencil, as I try to capture the thoughts which arise when I read the book. But, as nowadays we spend of our time on the internet, I wanted something so that I can keep my throughout written on that webpage, I tried various websites. Then I found Hypothesis – Web & PDF Annotation . It made my life a bit easier.

Using Hypothesis, a person can highlight the text or annotate it on the webpage they are visiting. And we can do that same thing with pdf.
