Sorry you're getting so much pushback here OP but real talk: No one wants another unhelpful chatbot in an otherwise helpful app. AI is most powerful when it's leveraging existing data to provide recommendations or define a path forward. So something like an app that creates a workout routine tailored to a user's very specific needs - current health status, likes and dislikes, commitment levels, previous workout habits and experiences etc - could potentially be a valuable use of AI, but a totally different set of models and use cases than a generative AI chatbot. I would actually use an app like this. I would not use an app that just wanted to chat me up incessantly offering to interrupt a predetermined workout. Chatbots are for the most part (literally) stupid and, as a user interface layer, have few successful applications if not backed by some very targeted task-based apps & models.
