Simplified “Focused Research”

Focused Research is a  feature that allows you to re-use your saving preferences with minimal effort.  Once you are in the research mode, the same set of tags, outliner and group are automatically applied to every item you save or annotate. This can be a big time saver when you are doing research on a particular topic.

This feature was hidden in extension options when we redesigned the Diigo extension previously. We simplified it and renamed it to “Remember saving preferences”.  Now it can be easily accessed in a bookmark window.

You can simply switch between focused research mode and usual bookmarking mode by turning on or off the “Remember saving preferences” option anytime you like.

Let us know whether you like it!



Introduce a new way to retain knowledge from Kindle books

Many Diigo users are lifelong learners and love reading books.  However, reading a book is one thing, retaining the knowledge from the book is another.  If you search “retain book” there are 122 Million results!  Many people struggle with how to better retain knowledge from books.

Highlighting is an important way to help retain knowledge.  As Diigo users, you’re familiar with highlighting on the web, and as Kindle users, you may be familiar with highlighting on Kindle as well.

Highlights can help to retain knowledge, but they are not enough. We still only remember the broad idea and message of a book.

“Well, the first rule is that you can’t really know anything if you just remember isolated facts and try and bang ‘em back. If the facts don’t hang together on a latticework of theory, you don’t have them in a usable form.”  — Charlie Munger

Isolated highlights are just like the isolated facts, we don’t have them in a usable form.    

Diigo provides a 2 step method to help you make the best use of your kindle highlights.

Step 1:   Import your kindle highlights to your Diigo library.

With the new Diigo chrome extension,  it only takes one click to import all of your highlights from a book to your Diigo library.

Step 2:  Organize highlights from a book in your own knowledge structure.

 After Kindle highlights are imported in your Diigo library,  it’s easy to add them to an outliner where you can then organize these highlights in your own structure.

As  avid kindle users, we have used this method for a long time and found it to be a very efficient way to integrate knowledge from a book to the knowledge network in your brain.

How many highlights are sleeping in your Kindle?   Import them into Diigo and  integrate them into a latticework of knowledge network now!   


Here is how to do it:

  1. Update to the latest Diigo Chrome extension
  2. Visit your kindle highlights page
  3. Click “Import to Diigo” button
  4. If you have highlights for personal documents on your kindle device,  you can follow instructions here  to upload the kindle highlights file to Diigo.

Outliner sidebar in Diigo Chrome extension — Organize knowledge while you collect them

The normal research process works like this “Collect first, Organize later“.  However, it becomes “Collect first, Organize never” very often.  Then, our library is cluttered with unorganized content.  This further causes   “Read a lot,  Retain a little” issue.  When the knowledge is not organized and connected together, it’s easy to forget them.

With the new outliner sidebar in Diigo chrome extension ,  you can organize your knowledge in a structured way while you collect them.  It  makes your research process much more efficient.

Here are some features in this update:

  1. Choose images from the sidebar and insert them into an outliner
  2. Better search in the sidebar panel
  3. Expand all annotations in an outliner

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 🙂


Diigo’s Refocus Back to Annotation


For the past few months, we have been hard at work on our website revamp. What started with the intentions of mainly updating our UI, made us take a step back and really consider what Diigo has evolved into after all these years and receive feedback from our users. After getting in touch with our cherished user base, we are beginning to plan our future direction. Here is a quick overview of the incoming changes. Please note that nothing is set in stone yet, and we will continue to evaluate all feedback from our users.

     When Diigo was created almost a decade ago, our goal was to provide our users with a simple platform to organize your online content and easily annotate web resources. While we have achieved these goals to some extent, we have allowed more and more features and functions to creep in along the way, resulting in an experience that may feel confusing or bloated, especially for new/casual users. Thus, we realized that we cannot clean up our UI without focusing on the functions that our users really appreciate and phasing out certain features that have strayed too far in other directions.

     A major change will be our movement away from ‘social’ aspects in Diigo. While we may have been swayed by the ‘social media movement’, at the end of the day Diigo has always been more of a personal platform. The ‘Discover’ section, including ‘networks’ and ‘communities’ will eventually be phased out. This section has always been very underused, yet takes a large amount of resources to maintain. This change will also simplify user profiles, which will focus mainly on each user’s public library, removing functions such as ‘follow user’, ‘public search’ and ‘message user’. This will allow us to focus on improving Diigo’s core experience.

     ‘Groups’ will also be evolving to the benefit of its main users, educators and enterprises. Almost all of our active groups have been focused on education or private content sharing within corporations, so groups will be evolving into ‘Diigo Teams’, which will also add specific functionality for each usage case.

    We will keep you updated on these changes as we approach our final direction, and would love to hear from you regarding these developments. Please leave your comments below or feel free to drop us a message via

    Thank you for your continued support of Diigo. With your support, we can make Diigo better for you.


Should Diigo Retain Social Aspects?



When Diigo was released ten years ago, our goal was to provide a social bookmarking/annotation service which would serve our users in two ways:

  • To provide the best online bookmarking/annotation tool assisting our users’ reading and research online.
  • The second is to leverage our users’ collections to create a social knowledge network to provide insight on what their friends and people with similar interests are reading.

Fast-forward to present day, Diigo has accomplished the first goal reasonably well, and through continuous improvement, we have maintained our leadership as the most popular and feature rich online bookmarking/annotation service in the world. Our goal to become a social knowledge network however has clearly been eclipsed by social networks such as Facebook, Twitter and Quora.    

Therefore, ten years later, we are at a major crossroad with a huge decision to make.  Should we forgo our aspiration to be a social knowledge network, and remove all social features?

As our social functions are some of the least used portions in Diigo, yet require constant maintenance, this would allow us to focus on providing the best personal online annotation/research platform for our users.  

As always, we would love to hear from you, our cherished users, and take your input into consideration.  If you do use some of Diigo’s social features, let us know which specific ones you would like to keep or see enhanced.
