Saying that you're going to "use AI" is more akin to saying "we're going to have a web application" back in 1998.
Back then a lot of startups didn't have websites, because they were making other products (hardware, boxed software, etc). If they had a website it was just a marketing page.
So saying that you were going to make a "web application" did in fact differentiate you, in that it showed your approach was very different from the boxed software folks, but it didn't tell you much beyond that.
