I’m not sure if I mentioned it here before, but last year I got myself a Chromebook (a 1st gen. HP Chromebook 14), to replace my aging and increasingly decrepit (or should I say decrapit) iPad 1 as my main portable note-taking and web-surfing machine. I quickly became a Chromebook convert, especially after I discovered how easy and convenient it is to use Chrome Remote Desktop to access my Windows 7 PC, thus always having my office with me.
The only area where my Chromebook and Chrome OS were lacking and where my iPad 1 (with the GoodReader app, for instance) was still superior was PDF annotation. It was certainly possible to read a PDF on a Chromebook but there was no satisfactory solution to annotate a book-sized PDF, both online and offline, and then be able to export the annotated PDF file or the annotations themselves. Not until Notable PDF appeared on the scene that is. I have been using Notable since its beta days on and off, but until recently I kept running into problems that made me return to annotating on the PC or on my old iPad.
However, in recent weeks I checked back again and I was very pleasantly surprised that Notable have ironed out some of the obstacles that kept me from adopting it permanently. Finally I was able to download my annotated PDF file and open it in PDF XChange Editor on the PC, and I saw all my highlights and annotations in place. It is still not perfect, as the highlights in XChange Editor show up as some kind of colour overlay rather than XChange’s own native highlights, but hey, I can live with that. What is more important is that I am now able to read and manipulate my Notable annotations in XChange Editor.
Moreover, Notable has some tricks up its sleave that give it a distinct advantage over some other PDF annotating options. Notable PDF is a Chrome browser extension, which makes it cross-platform on desktops, as long as you have Chrome installed on your other machines.* It appears to save the annotations in the cloud, which means that it doesn’t matter where you keep your file, and how many copies of your file you have, it will sync the annotations to that file (and its copies) across all the browsers. You can even have two different copies of the same PDF file open in different machines in Chrome, and the annotations will sync live and automatically, in front of your eyes. This feature of course would be very useful for collaborations, as you can see instantly what others are commenting on that file.
To me, this feature means more flexibility. For example, the copy of the PDF file I’m reading is saved on the hard drive of the Chromebook. When I’m offline, the annotations are saved offline, and then synced when I’m back online. However, I also have a copy of the same file on my Google Drive account in the cloud, and if I’m on another machine, let’s say a PC at work and I do not have my Chromebook with me with the original file, I can just open the copy from Google Drive, and Notable recognises it as a copy of the annotated file and it populates it with the annotations saved on their server. I find this rather clever and very useful.
In any case, I just wanted to say that I’m happy now to include Notable PDF among my favourite apps and recommend it to others, especially Chromebook users. While it’s not entirely perfect for my needs (I wish the yellow highlights could be converted to native highlights in PDF XChange Editor, so they can be extracted from there), it is probably the best option for PDF reading and annotating on Chromebook today. Also, I have been following them for the past year, and development has been on-going, so I am hopeful that Notable will continue to be improving.
* Having just looked at their website more closely, it turns out now they also have a web app, so in fact you can use their service on any browser, not just Chrome.
