An AI that creates an interface based on a verbal description.

As I understand you are asking about a new feature for grouping separate artboards and describing selected group- something like a note or hint. I think group would be better as each user have different resolution of screen and screens can be differ from user to user. 

This can be interesting idea. Something like a Frames that we have in Adobe Substance Designer

Frames

The number one thing that leads to cleaner, easier to read graphs, is the placement of Frames around core groups of your graph. Without Frames, a big Graph is almost unreadable, and even small Graphs become much easier to understand once frames are drawn. A huge advantage of Frames is that their names are always rendered at the same scale, even if you zoom out very far.

Frames make it much easier to understand what is going on in a graph. They can help you as an author coming back to your work months later, or another user such as a colleague to find their way around a Graph they are not used to.

Use the following criteria when placing Frames:

• Identify chunks of functionality (for example a 8 nodes that together create a dirt effect) and group these using Frames.
• Always try to use different colors for your Frames: Frames with the same blue, default color don't stand out much from each other.
• Use clear, descriptive names that are not overly long (see section below for more tips)
• Don't put too much or too little in a Frame, as this doesn't help readability. The exact amount obviously differs between graphs and functiuonality.
• If neccessary, add text in the description to help understand what happens in a frame
