Nice Job. This really highlights that people who obsess in telling us that "AI hallucinates", and "AI isn't intelligent", are missing the point. At the end of the day, it's simply useful, and incredibly empowering.
Yes, without AI this app definitely would not exist as I would not have had time to make it. I think that this will apply to multiple other areas within the economy.
Another thing to add: developers don't have the time or don't want to spend time on apps like this, but it's not like this is anything complicated.
This app ultimately amounts to something that has been done millions of times, and so I think it's actually quite empowering for individuals to be able to quickly build mockups of apps like this for themselves without needing to spend upwards of $75/hr to hire some freelance dev to do it for them.
