# Carthalis

> Carthalis is an AI health executive assistant and personal companion for long-term wellness — wellness education and coaching, not a medical device.

Carthalis unifies conversations, lab uploads, surveys, logs, and optional wearables into one picture that deepens over time. It investigates what matters, plans your path, and follows through across nutrition, fitness, sleep, and medications — with research-informed insights and 130+ educational wellness scores. Wellness education only — not diagnosis, prescription, or treatment, and not for emergencies. Visit https://carthalis.ca for the full experience.
