Who's using Open AI in their apps now to help users search for content?

In our new app BionicFit (on iOS) I think it's a really great feature because people can request targeted workouts and they get them immediately. If the user has a training issue or injury, Open AI addresses the problem fairly well.

For those of you who have implemented it in your apps, what sort of response are you getting? Are people finding it useful or gimmicky?
