hey, so i've messed with this a bit myself for a while. it's tricky but def doable if you're consistent.
- find one base AI model/generator you like and stick with it. switching models messes up the style.
- use similar prompts every single time. same adjectives, art styles, even specific seed numbers if your tool lets you.
- then it's a lot of post-processing. same filters, color grading on all images helps unify the look.
it's mostly about limiting variables imo. good luck!
