PDF Tools for Teaching

As we’ve been transitioning our in-person learning centers to be fully online, the question has come up about how to use slides and work with students. While Zoom offers screen-sharing and annotation, the annotation on an actual slide persists on the screen: if you scroll to a new slide, the annotation remains. There’s no way to annotate a document using Zoom. Even worse, the “whiteboard” feature in Zoom, though cool in many ways, really loses out by having no way to paste formatted text, or even images, onto it. That takes away significant functionality.

At our learning centers, we use a Windows-only piece of software called Drawboard. It’s a pretty nice piece of software with nice annotation tools. It could be a bit more fully-featured (making straight lines or shapes is rather difficult/impossible), but our teachers are used to it. However, it’s $12 and we can’t expect teachers to buy it. Furthermore, all of our teachers are working from home, and many will be using Mac (or even Linux, believe it or not!) So, this isn’t an option. Luckily during my time training, I got some recommendations from a few resourceful teachers.

First is Xodo. It’s a browser-based app where you can import and mark up PDF documents. That’s really all there is to say. It has the same features our instructors are familiar with, and works pretty fine. I actually had some trouble getting it to be as responsive, but I haven’t heard that complaint from others, so it might be specific to me.

Another is bitpaper. This one I really like. It has collaboration features (although teachers likely wouldn’t use them), but it’s much sleeker than Xodo in my opinion. It has a more “iPad” feel to it, with the tools in the bottom very similar to those in the Apple Notes app. It has basic straight-line drawing and keyboard shortcuts.

I’m still working on properly vetting these before we can officially recommend as a company, but they all pass the smell test for me. Even if you aren’t a teacher and just want simple PDF tools, I think Xodo is a good place to start for a lot of mark-up, and bitpaper is excellent for easy collaboration.
