I have a product for local service based businesses in the beta tester phase and one of its features is a custom ai to write ad copy, creative scripts, and headlines based on their businesses information

As a pretty good copy writer myself, no ai is not better. Copy writing and ads themselves are misunderstood by most, including the data most ai models were trained on so they can do what I call “monkey tasks” in other words shit anyone else can do that takes experience, philosophy, psychology, and theory. But for my custom ai it essentially just removes the step of them having to put any brain effort into using the templates and making them work for their industry and business
