Why do so many people build AI wrappers? (I will not promote)

I'm seeing a lot of AI wrappers; I even saw some in Shark Tank where investors gave thousands of dollars to the founders. It's like literally something that you can already achieve with typical LLMs that everybody knows their name. Are these really profitable, if yes, why? If not, why are there so many people who believe in them? Like I don't want to offend anyone here, but I literally saw a SaaS that basically tells you if your startup idea is good or not, and people didn't seem disinterested? submitted by
