## Trying Kai Theme Creator on a Starter or Smart site

In SimDif, the website builder developed by The Simple Different Company, users on a Starter (Free) or Smart plan can access the Kai Theme Creator. This tool allows users to follow the steps to create a complete graphic theme and preview how it will appear on their site.

In SimDif, a graphic theme defines the visual appearance—including colors, shapes, and fonts—independent of the page content. This architecture allows users to switch themes at any time without affecting the arrangement of their content blocks or site navigation. 

Users on Starter or Smart plans have the ability to save the themes they create within the interface.

#### To publish your site with a Theme you create with Kai, or to edit the Theme, you will need a Pro site.

To apply a theme created with Kai to a live published website, or to modify an existing theme, the site must be on a SimDif Pro plan.
