Basically it's based on Stable Diffusion, but does many others, offers styles and you can also go advanced and use your own original images. Variable seed or select, use the same. Same in so many ways as the rest for size. I'm finding it's different from DALL-E and doesn't make the icons and illustrations, logos I mean, as well. Seems that NC wants to be more complicated and intricate.
Making cartoons and illustrations, the results for mine have been better than DALL-E.
All the usual flaws and problems of AI images, but since it's free and you can get a minimum of 5 free credits a day, where 1 image is 1 credit, there's some good fun.

But give it a try, another source for fun graphics.
