What to use for casually making ai images?

One of my hobbies right now is writing lore for a fictional medieval/fantasy world I’m building.

I use Gemini right now for generating ai images based off of my descriptions of the landscape, scenes, etc. I recently found out my ChatGPT app could do the same all of a sudden. However I was limited to, I shit you not, 4 images before it forced me to pay $20/month just to even continue texting with it.

Considering that’s more than my Gamepass Ultimate subscription or any other subscription I have for that matter I felt disgusted by even using ChatGPT.

Is there any other Ai’s people use to generate images just for fun that I can use? Or I might as well just keep Gemini (which I don’t pay for and it seems unlimited, but limited as to what it can understand and create.)
