One of the most underrated tools on the internet. I've been using it consistently for a little over 2 years now for everything from keeping track of random ideas to SEO & Web Design. 🖤🖤🖤

A robust way to annotate web sites, and the relocatable PDF annotator is pretty cool, too. I can imagine some usability improvements that would make for a more natural user experience, and some features that would be helpful, but all in all a great product.

I've been using Hypothesis since January 2018. This is the number one extension that I install on a new computer. The search function is amazing, it helps me to recall sites and annotations on any topic that I care to re-search. As my laptop died recently and had to install this extension, I took this opportunity to write this review. My mind boggles, how come not everybody is using this. Kudos to the whole Team

Lovely. From copying notes on Word files to saving web pages, I have struggled quite a lot keeping track of interesting content. With Hypothes.is, this is no longer a problem. I can have all my annotations in one place and choose to go back to them whenever I want. Kudos to the makers!
