Animated whiteboard videos

Anyone have recommendations for software for making whiteboard videos, either online (browser based) or available for Windows and Mac?

MOST IMPORTANT: Must be easy. The person who will use this is very novice.

Squigl is a company local to me here in the Madison WIsconsin area. I saw a demo of the software a while ago. You basically feed in a text script and it automates animations by matching keywords to their library.

Do you mean animated whiteboard videos for training and comms purposes or just whiteboard apps for collaboration, meetings etc? Very different use cases.

I mean animated videos, like explainers.
