Document manager for PDF, web content, books, and notes with tagging, annotations, and highlighting.
Polar is a powerful document management platform for the web, and desktop including Mac, Windows, and Linux for managing all your web content, books, and notes. Polar keeps all your content in one place, supports tagging, annotation, highlighting and keeps track of your reading progress. Polar supports PDF as well as web content and supports fully offline operation and archives your documentation long term. Polar is both a web and cloud-aware desktop app and allows you to manage your reading and cache web pages offline for long term archival. Polar supports a number of powerful features including: - 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. - Full caching of web pages for offline storage and archival keeps the full fidelity of the web page available for your use over the long term. - Pagemarks allow you to easily keep track of what you're reading and the progress of each document. Pagemarks enable non-linear reading and the ability to suspend and resume individual documents for later consumption. - Offline-first: All content is stored locally. You can also use a system like git or Dropbox to transfer your repository across machines. - Hackable: The entire system is Open Source and based on Electron, Node, pdf.js, React and other web standards. If you're a developer - welcome home! - Standards Based: All content is stored as JSON in a well documented schema. Annotations never change the original content which keeps your document repository safe. - Fully cloud-aware with replication across desktop and web including Linux, Mac and Windows and web. ANNOTATIONS 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. DOCUMENT REPOSITORY The document repository allows you to manage your documents in one place - sort by reading progress, or time added, archive and filter flagged documents. 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.

- (2019-12-12) Casper Thalen: In 5 years of uni, no single tool, tip or habit has improved my grades as much as the polar+anki combination. It's like cheating, but allowed.

- (2019-05-08) GoldenGirl2803: this is one of the best extensions iv ever used, im studying with open university and this easily holds my coursework and PDF eBooks so its all together tidy
- (2019-04-20) Austin Acton: Love the desktop app and the web app as well. I want to completely adopt this to replace my use of Instapaper, Pocket, Evernote, and Zotero combined. However, it falls short for me in: - current Chrome page to extension to local viewer to document repository is a very clunky and uncomfortable workflow (similar to the old, outdated software Zotero I'm trying to replace) - Chrome extension can't save a webpage to the webapp or to the Linux app running in a container, so, mostly useless on a Chromebook, which is my main research machine - no Android app and no plan for deep integration with Android ecosystem even if an app is developed - expected pricing plan with pretty severe usage limitations planned for the future makes the "better than Evernote" and "you're in control of all of your own data" claims hard to swallow
- (2019-04-09) Lenny Leopere: The internet can be a bit of an amnesiac at times this helps you take a bit more control over when things are truly forgotten. You no longer have to leave it up to other people to do a good job of making sure when websites disappear the knowledge no longer has to. Also it helps that it does annotations and flashcards for helping you remember and digest complex topics. A really excellent study tool!

- (2019-03-14) Manny Barreto: Great for students!
- (2019-01-21) Jonathan Hawley-Peters: So far so good, this clipped an article and seamlessly sent it to Polar for reading later. I've recently tried the Evernote Web Clipper, Liner, Mind Forger, and Anki, in an attempt to: 1. save articles for later 2. read and annotate 3. review Right now, Polar shows the most promise. One clear advantage is that it's not in-browser and therefore less likely to distract me while reading.

- (2018-12-03) Douglas G.: Pretty nice app and extension. Recommended.
- (2019-06-05, v:1.19.0) Yilun Zhang: Failed to Save!
Hello, I have the Polar Bookshelf downloaded, the chrome extension downloaded, and I am running on a Mac. Each time I click the Polarbookshelf extension button it says that it failed to save because the Desktop app needs to be running in the background but it is.... Am I missing something?
