While designing my Practical Appreciative Inquiry online course pilot (now concluded, but email me if you are interested in the full-featured course that I’ll be launching soon), I auditioned various virtual whiteboard tools for online collaboration.

These can be very useful for a virtual team or distributed group to quickly knock together a presentation, a high-level plan, or collaborative vision boards for the ‘Dream’ stage of an Appreciative Inquiry process.

This doesn’t pretend to be a comprehensive evaluation of every whiteboard tool and app out there (there are loads of them), but a quick comparison of the ones I tried out, with pros and cons.

I’ve also included the one I found after the course had finished, that actually would have worked much better for my needs than the ones I used.

I tested the free entry-level versions only, so this is what the pros and cons apply to.

1. Twiddla


  • No signup needed
  • Up to 10 users free
  • Various text options (standalone, ‘sticky note’, box, speech bubble)
  • Participants can upload their own images
  • Eraser tool so you can erase part of an object


  • Free session limited to 20 minutes!
  • Limited palette of shapes (line, rectangle, round-cornered box, circle/oval)
  • No arrows
  • Ugly (to the eye of this Mac user) old-fashioned Windows-looking user interface. Rather ‘skeuomorphic’ design with drop shadows.

2. Sketchboard

Tool aimed at software design teams


  • Some pre-made images (aimed at software designers, but you do get smiley faces, ‘people’, lightbulbs, clouds, speech bubbles)


  • Still not that many pre-made images
  • ‘Undo’ button seems to be the only way to erase mistakes
  • Boards on the free plan can have only up to 5 collaborators

3. Google Drawings


  • Very similar to the ‘draw’ tools in Microsoft Office, so no learning curve for most users


  • You have to be signed in to Google (e.g. with a Gmail account) to be able to draw on the board
  • Still quite a limited library of built-in shapes

4. ‘Whiteboard’ tool in Zoom

Even many people who use Zoom.us as their course delivery or call platform (I prefer it to Skype as a) call quality seems to be a bit better and b) you can record the calls very easily without additional plugins) don’t seem to know that it has a whiteboard feature inside it. You can share the whiteboard with your call or course participants and allow them to draw on it.


  • Right there in Zoom
  • Eraser tool
  • So limited that there’s not much of a learning curve


  • Free version of Zoom only allows 40 minute calls if more than two participants
  • Very limited library of shapes (rectangle, oval, diamond, arrow, heart, star, tick)

5. Miro


  • Lots of templates (e.g. Kanban, customer journey, mind map, fishbone, Venn diagram, 6 Thinking Hats, and more!)
  • Includes ‘Icon Finder’ app so lots of images immediately available – I found many choices for cars, dogs, even zombies!
  • You can change transparency of objects
  • Lots of export options
  • Unlimited team members


  • None that I could find

So Miro is the clear winner! I was actually amazed at how many features even the free version has.
