# FitViz AI

> FitViz AI is an AI fitness coach that reads your heart-rate variability (HRV), sleep, and daily readiness to build personalised workouts that adapt to how your body feels each day.

FitViz AI pairs wearable data with a conversational AI coach. Each morning it scores your readiness from HRV and sleep, then adjusts that day's training so you push hard when recovered and ease off when you are not. You interact with the coach through chat and voice, it plans and adapts workout programs over time, and it explains the reasoning behind each recommendation. The product lives at https://ai.fitvizpro.com.

## Key facts

- Product type: AI-powered fitness coaching app delivered as a web app and installable progressive web app (PWA).
- Wearable integration: connects to Garmin via Garmin Connect to pull HRV, sleep, and recovery data automatically.
- Core mechanic: a daily readiness score derived from HRV and sleep that drives how hard or easy each workout should be.
- Coaching interface: conversational chat plus voice interaction; the coach builds programs, adjusts them day to day, and explains its decisions.
- Focus: adaptive, recovery-aware training for everyday athletes who want workouts matched to their current state rather than a fixed plan.

## What FitViz AI is not

FitViz AI is a fitness and training tool. It does not:
- Provide medical, clinical, or diagnostic advice, and is not a substitute for a doctor or qualified health professional.
- Treat, diagnose, or monitor any medical condition.
- Provide nutrition plans, meal planning, or dietary prescriptions.
- Replace supervised training for rehabilitation or injury recovery.

Always consult a healthcare professional before starting a new exercise program, especially with an existing health condition.
