As a developer, I would love to have this! However, after talking to our users, the biggest thing that we consistently hear is that they love the community, and the coaches.
For example they can talk with Coach Amy on social media, chat with Coach Rory on Clubhouse, and see Coach Justin making a funny TikTok. The relatable coaches may not be the reason that runners are coming to the app, but they're definitely a major reason into why they stay.
I wonder what the liability concerns with this are. Could a runner that gets injured because the AI coach bugs out and tells them to do something dangerous (e.g. extreme overtraining) sue?
