It seems to me that OP's tool is not meant to replace the human creative process, but to support it.
Like an intermediate step in the creative process that allows for more iterations.

That seems like a very black and white way of thinking. Where do you draw the line between human and 'machine-assisted' creativity?
The second you start creating a mood board for your next project, you've probably already taken advantage of algorithmic feeds and content aggregators, but it's still you feeding the machine with querys etc.
I assume that they are talking about easing gradients, which is interpolating the gradient’s color stops using a cubic bézier easing function [1]. It gets rid of the sharp edge you sometimes see in linear gradients. Think of CSS animations and their easing-functions.
There are various Sketch and Figma plugins which let you modify the easing function and generate the CSS for it.
