Can it show my actual product?+
It draws from what you give it: describe the screen, the box or the device in the premise or on a model sheet, or add a picture that's yours to use. It's a drawing in your look, not a screenshot, so expect the comic's version of it.
How long is an explainer?+
One issue. It's written and drawn as a short comic, panel by panel, and can stop there — or go on, one issue a feature.
Can I put it on my site?+
Yes. A finished issue downloads as a narrated video, or as its panels in a zip with the captions, and the comic is yours to use.
