# Features

research which is often stored as PDF.

- **EPUB support** Add any EPUB and we also capture web content to EPUB/

- **Captured Web Pages** Download HTML content and save them as offline documents which can be annotated.

- **Pagemarks** Easily keep track of what you're reading and the progress of each document.

- **Text Highlights** Highlight text in PDF and web pages.

- **Area Highlights** Capture a region of the page as a highlight which can be a chart, figure, infographic, etc.  

- **Portable** Run across any platform. ```Linux```, ```MacOS```, and ```Windows``` supported.
