Let's say I want to use this image below of alphabet soup, but have it spell out a custom phrase.

Below is an example where I selected the middle portion of the soup and using Generative Fill told the AI to generate the phrase "Bar Mitzvah". You can see that it struggles with building the phrase correctly, but understood the idea that it had to use "noodle letters" to spell it out.

Because the AI was able to understand where to pull the type texture from and how to rebuild it, my thought it that it could use this information but then apply it to live type. So once you approve the AI output for how the type should look you can then create a type box and input your phrase so that the words are correct, and you can move them around in real time for placement.
Beyond this, I could then see selecting a font so that you have the aphabet soup noodle texure, a live type box with your exact phrase, and you can then tell it to keep the texture and placement but make it cursive, or serif for example.
