We have first-class PDF support thanks to PDF.js. PDFs work well when reading content in book format or when reading scientific research which is often stored as PDF.
Captured Web Pages
Download HTML content and save them as offline documents which can be annotated. Captured pages are rendered for greater readability using CSS browser emulation.
Easily keep track of what you're reading and the progress of each document. Pagemarks enable a form of non-linear reading named incremental reading and the ability to suspend and resume individual documents for later consumption.
All content is stored locally which means you can use Polar while offline. Polar cloud sync allows you to use Polar with other computers as well.
The entire system is based on
React and other
web standards. If you're a developer - welcome home!
All content is stored as JSON in a well documented schema. Annotations never change the original content which keeps your document repository safe.
Annotations are a central feature to POLAR. While reading documents you can underline text or create area highlights. Once created, you can attach additional metadata to annotations such as comments and flashcards.
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.
