New Diigo extension released

As we said in Diigo’s Refocus Back to Annotation  last April, Diigo would shift our primary focus back to “annotation”.  We made a big upgrade to Diigo website in October 2016.  Today,  we are glad to release the new Diigo extension for Chrome.

Here are some new features in this new version.

1. New design with simplified extension menu

2. Annotate articles in an ads-free reader
Annotating web article is a common use case among diigo users. However, many article pages are cluttered with ads, sidebars, headers and footers. A better reading experience comes together with a better annotation experience in this new version. Once you experience it, you will never go back!

3. Annotate your local PDF files directly in Chrome
Previously, to annotate PDF files, you needed to upload local PDF files to the Diigo website. Now with the built in PDF reader, you can annotate them in Diigo Chrome extension directly.  It’s  now faster and much more convenient to annotate PDF files.

4. Get support from extension
With the built-in “Send message” feature, it’s much easier to send support messages to the Diigo team and get  problems solved quickly.

5. Other features are still available in this new versionextension1.png

If you like Diigo extension,  please help us spread the word by giving the extension a 5-star rating on Chrome web Store.

The Most Powerful Tool for Writing Papers: Diigo 7.0 Released!

Diigo 7.0 is perhaps the most significant version upgrade in Diigo’s history. We are confident that you will find the new Diigo to be the most powerful personal knowledge management tool that can help you harness information, build coherent knowledge, and speed up learning.

From pieces of information to a coherent knowledge structure

With this upgrade, Diigo makes it significantly easier to go from pieces of information to a coherent knowledge structure, which all pedagogy theorists agrees is one of the most important steps in learning, memorizing, and writing.

An important innovation introduced in Diigo 6.0 is Outliners, which allow you to organize information as knowledge trees.   The importance and benefit of knowledge trees in learning are perhaps best articulated by one of the greatest innovators of our times, Elon Musk:

I think most people can learn a lot more than they think they can. They sell themselves short without trying.

One bit of advice: it is important to view knowledge as sort of a semantic tree — make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.

— Elon Musk

While outliners are powerful, going from information collected and digested to knowledge trees  still feel disjointed and awkward.  So a key innovation in this upgrade is to enable a split view with outliners and my library side by side:


With this split view,  one can

  • Read an article on the left side,  drag-and-drop specific bits to specific locations of the outliner tree shown on the right side.
  • Drag an item in My Library shown on the left side  to specific locations in the outliner tree shown on the right side.

After the user has built a coherent knowledge tree, he can then export the outliner to a word processor for further editing.   The split view therefore seamlessly integrates the multiple steps involved in writing papers, from collecting, reading and digesting information, to connecting and organizing pieces of information coherently.

Heads-up for future improvement:    The Diigo extension is being reworked to provide the same seamless experience from reading, annotating to outliners.

Better UX with modern feel.   

With its advanced annotation capability, Diigo has been the best way to collect, read and digest information, both webpages and PDF documents. This upgrade just makes it even better with a sleeker UX and modern feel.

The new UI is not only better looking, but also simpler and easier to use.  There are many small improvements waiting for you to discover, such as “in-place tag editing”, new “bulk edit” feature,  better “Generate report”  etc.


Annotate directly on without the extension.   

Previously, if you want to annotate an article, you need to install Diigo extension or Diigolet. Very often, the article webpage is cluttered by ads.  Now, you can have immersive reading experience for articles in an ads-free environment in the new version.   Even better, you don’t need to install extension or Diigolet to annotate on web pages.   


We want to  express our appreciation to all users who participated in our beta testing. Your input has been valuable and helps to shape the new Diigo. And we are not done innovating yet!  Just wait and be pleasantly surprised 🙂


Scheduled Maintenance Notice 2

The scheduled maintenance is the second step for a backend upgrade.  We will move Diigo from current data center to Amazon cloud.  You will experience a faster and more stable Diigo after the migration.

The planned maintenance window is Wednesday, Feb 11th at 0:00PM US PST.  We expect the actual downtime to be approximately 1 hour.

Annotating PDF Docs with Diigo – A Tutorial  

There are two different methods with which you can annotate a PDF doc with Diigo.

(If you don’t want to read the tutorial,  try the PDF annotation feature directly.)

Mehtod 1:   Annotate a PDF doc by first uploading it  to the Diigo website

  • Step 1:  Upload a pdf doc to your diigo library in “My Library” page;
  • Step 2: Open the uploaded PDF doc in your browser, and you should see a toolbar on top of the doc;
  • Step 3: Select text to highlight or add a sticky note. Your highlight and sticky notes on the PDF will be saved in your Diigo library.


Method 2: Annotate a PDF using the  Diigo browser extension (available for Chrome and Firefox only, and the instructions below are for Chrome)

  • Step 1: Open an online PDF doc,within Chrome, with the Diigo extension installed;
  • Step 2: Click the  “Annotate” button at the upper right corner of the opened PDF doc (see the first screenshot below). The doc is then opened again with a toolbar on top (see the second screenshot below);
  • Step 3: Select text to highlight or add a sticky note. Your highlight and sticky notes on the PDF will be saved in your Diigo library.


How to Annotate and Clip non-text PDF Doc

If a PDF doc is in a form of an image, then you cannot highlight any text, but you can use the screenshot feature of of the Diigo extension (chrome and firefox) to capture or crop the image, and then annotate it as a screenshot.



Export an annotated PDF doc

The annotated PDF doc can be exported.  However, due to some tech limitation, after being exported, in-line sticky notes are invisible  for mac users who use preview as their pdf reader.

Due to the complexity of the PDF format and the compatibility issues for different browsers and browser versions,  Diigo PDF annotation may not work perfectly for every PDF file. If you experience any issue,  please do let us know.
