Building AI to Look After Your Health

Nox opens straight into the chat: ask any health question and get an answer with Leo — Nox's visible safety guardian — watching over it. Free to start, no credit card required. <a href="/chat">Open the Nox chat</a>.

Nox is an AI-powered health and wellness companion built by Xhealth, Inc. You talk to Nox in plain language — about symptoms, sleep, nutrition, medications, and everyday wellbeing — and Nox answers clearly, screens for warning signs, and helps you understand when something may need professional care.

Unlike typical smart-ring apps that mainly display data dashboards, Nox is designed as a conversational AI companion at the center of a smart-ring ecosystem — you talk to it, ask it health questions, and it helps you understand your body in plain language. Nox is a companion and educational tool, not a medical device, and not a replacement for a clinician.

Every conversation runs on the Nox model family, and every answer passes through Leo — a visible safety guardian. The "world's first" claim behind Leo is dated, criteria-scoped, and open to challenge: <a href="/leo-first">see the evidence</a>.
