Cross-platform supported on MacOS, Windows, Linux, Chrome, Firefox, and Safari.

Polar is fully cloud-aware for real-time synchronization across multiple devices but also supports local storage for offline work if you prefer

Polar supports all platforms including MacOS, Windows, Linux, and Firefox.

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.

Browser emulation

Emulate multiple browsers and mobile content to make sure pages captured are rendered properly.

Personal Archive

All content is stored in a personal archive which allows you to refer back to important documents and view annotations over time.

Captured Content

Integrated Annotations Sidebar
