watt-mind/coach ? reverse-engineered prompt

Build me a self hosted web app for endurance athletes that feels like an AI coach and fitness dashboard in one.

I want it to let cyclists, runners, and triathletes connect their fitness accounts, see all their activity in one place, and get useful AI guidance like workout breakdowns, daily recommendations, and training plan suggestions based on recovery, sleep, and stress. It should also show the usual training stats like fitness, fatigue, form, power curves, and a clean calendar view for planned and completed workouts. If possible, include nutrition tracking and a chat style coach that can answer questions about training using the user’s own data.

Make it support multiple languages and be built so I can run it myself with a database and log in securely. Use the current docs online if you need to check anything. I’d like it to feel polished and modern, not just a demo.
