The example currently on my mind comes from what I'm doing at work. And that despite my heavy skepticism, I've become "Mr. AI" at my job.

Currently I'm working on an AI powered chat experience that homeowners can interact with to answer questions about their improvement projects and even get dynamic cost estimation from some of our APIs. It costs the homeowner nothing to use, but eventually (what I'm currently doing anyway) it will have a monetization/conversion hook added to the flow.
