Should I add AI to my resume builder?

I don't see why not. Now of course, just adding "AI expert" won't cut you any second glances. But something like "Prompt Engineer with live projects in text2text,text2image, etc" will be a better format.

it depends. there should be more & specific skills such as Prompt Engineering.

Adding AI to your resume builder can differentiate it from competitors by offering personalized recommendations and smarter matchings, but consider the complexity and whether your target audience would benefit from this feature.
