Hi Product Hunt! I'm Artem, the solo maker behind Vitality AI Coach for Garmin. A few years ago a coach kept my Garmin logs and "interpreted" them for me — at subscription prices. Meanwhile, my watch was already recording my HRV, sleep, stress and body battery every single day. The data was there; it just never said anything. So I built the coach I wanted. It reads your Garmin Connect data and answers plain-language questions — in English or Russian. Why is my Body Battery low today? How does my HRV compare to my 30-day baseline? Should I train? It cross-references sleep, stress and training load to surface patterns you'd otherwise miss. What makes it different: it's 100% self-hosted. Your health data never leaves your machine — credentials and chat history stay encrypted. It runs on free LLM tiers (Groq, OpenRouter) or fully offline with Ollama. And it's open source (MIT), free forever — because you deserve to understand your own health data without a subscription. Under 5 minutes to set up with Docker. Would love your feedback — and tell me: what would YOU ask your Garmin data?
