Even for my placeholder cover, which is just a Bing AI prompt until I can commission a real human artist, still manages to attract a reader or two each week.
Sure, I typed a few fancy letters from Adobe Express for the bilingual title and my pen name, but that's one of the ways you can grab an audience's attention. That's not the full picture, however. You could prompt the most generic AI waifu and slap in a "graphic design is my passion" title, and the story would still have to be carried by decent writing and grammar (or delivering the raunchy smut they want out of the said cover).
