Yeah dude no worry, it's called Midjourney the one that I use, but I use the paying subscription that allows me to commercialise what I make. Let's imagine I make a pattern for a blanket or a mouse pad with midjourney, I can sell it.

There are a plethora of other Ai art apps: Night Cafe studio (which is ok, not the best), stable diffusion (a bit harder to understand at first if you aren't tech savvy), Midjourney that you use through Discord, there is a new one called BlueWillow and it looks decent! You can still use Midjourney for free, but you won't be able to commercialise what you make, though I am sure if you post what you do here and make hive, nobody will say muffin hahah...
