The greatest trick in UI development

This is where I want AI the most in UI dev. I've seen some apps for this, but I haven't seen one that is a fully automated AI that compares snapshots in realtime while it clicks around and checks for behavior as well. A big gap in UI testing, whether it's visual or unit tests, is testing the behavior. How great would it be to add a prompt of a list of requirements and have an AI test it locally, and then report on which requirements are not being met.
