There is a new AI Image creator online almost every day. I usually get myself a free account, experiment with the settings and then decide to either use it on a regular basis or only now and then.
Cogniwerk AI is one of my "newer" AI Image creators. To create one image costs one credit; every account has been given a certain number of credits, and when you have used up your credits, you can request more.
Many AI Image Creators have difficulties with horses - they tend to create animals with five legs. I wanted to know what Cogniwerk does with a prompt like this:
A black mustang galloping over a yellow green meadow, vector style
Well, it actually added an additional leg where it does not belong. However they offer Inpainting, and so I managed to create the anatomically correct mustang in the image above. So up to now I am very pleased with Cogniwerk AI and will use it regularly.
