I'm trying to find one that I can use for free but they all charge between $40-$100 for an AI generated logo! I just want one for a company in my Starfinder game!
If you have a (preferably NVIDIA) GPU, you could run one of the many applications that use Stable Diffusion on your PC. I have only used these before:
Fooocus: Really easy to set up, but not really meant to be used with other custom models, has lots of artstyles to choose from.
Automatic1111: Also pretty easy to set up, maybe a little bit harder. You have to download the models from somewhere else, but its much easier to import them and it has lots of options.
Fooocus will probably suffice, just select a fitting art style to get a good look.
