Can I try Kai Theme Creator on a free Starter site?

Trying Kai Theme Creator on a Starter or Smart site

Yes. On a Starter or Smart site you can open Kai Theme Creator, go through all the steps to create a complete graphic Theme, and preview the result on your site.

You can also save one Theme.

To publish your site with a Theme you create with Kai, to create more than one theme, or to edit the Theme, you will need a Pro site.
