Did you try the demo on the homepage? I would have thought a demo of the actual product would make it clear what the actual product is.
Also, the interactive playground DOES make it seem like it is trying to be a code editor, except it is implemented in codepen which is pretty confusing. I get that you're showing how to render the JS and all but only because I've spent time poking around a lot.
That all said, next time I need a WYSIWYG I know exactly where to go! Thanks!
I'm talking about initial messaging communication here. A demo is not for that - that comes after.
