Agreed. I was confused at first. Maybe just call it "the easiest way to create step-by-step screenshots"? Or maybe something like: "Show them exactly what you mean: The easiest way to create animated, step-by-step screenshots".

I'm not sure about 'animated' unless you mean a powerpoint-like slideshow like what jasonkester suggested.

I like "Show them exactly what you mean".

Good point, I was thinking:

"Easily reply customers with step-by-step screenshots"

but would I be boxing myself in, because I think it's good for regular sharing between friends, family and co-workers too?
