Captured (and Offline) Web Content
Polar supports reading and annotating HTML documents. We call this process 'capturing' content and we store the document permanently in your own private archive.
Since most pages aren't designed for reading and have ads, chrome, and other annoyances within the page, we render the content as a tablet device to make the content more readable.
Emulate multiple browsers and mobile content to make sure pages captured are rendered properly.
All content is stored in a personal archive which allows you to refer back to important documents and view annotations over time.
Integrated Annotations Sidebar
All annotations are easily accessible in the sidebar. You can create flashcards, add comments, and jump to any text highlight in the main document at any time.
