The description on their page doesn't read like AI to me. Especially given that they classify things like this as AI: "Setting up shop online is too much work with all the management, databases, checkouts and security. Our AI removes the need for plugins, configuration and constant stress. Have a product, add a price and a shopping cart magically appears on your site. Just like that, just as it should be!"

All in all, it looks more like a blogging platform with templates that adapt to your content than actual AI.

EDIT: "The Grid" is the company behind the NoFlo flow programming tool... based upon their GitHub repos it looks like they reimplemented Jekyll using NoFlo and are using that + their adaptive templates to power the app. An interesting approach.
