About Carthalis
Why we built your personal health companion.
We build health tools that work for you — you own your data, choose what to share, and get clarity and a daily plan that fits real life.

Why we built Carthalis
Carthalis is built for anyone who wants one clear picture of their health and a daily plan that fits real life — not another dashboard to manage alone.
We started Carthalis because timely, understandable wellness context still reaches too few people — especially where access to personalized guidance is limited. Scattered labs, habits, and questions deserve one place that turns them into clarity, coaching, and follow-through you do not have to chase.
That is the whole product: a growing picture of your health, one home screen for what matters today, and a coach that keeps follow-ups going.
What we believe
Carthalis is built on ethics that put you first — with honest limits on what wellness tools can promise.
Your data works for you
You retain ownership of your health picture. Carthalis uses what you choose to share to personalize coaching, scores, and daily plans — with clear consent and purpose.
Transparency
We explain how AI supports your wellness journey, what our tools can and cannot do, and how your information is handled — so you can make informed choices.
Non-exploitation
We will never sell your health data. Any research participation is separate, opt-in and transparent, and you can stop at any time.
Who's building it
Carthalis is built by Aziz Mezlini, PhD — machine learning for health, trained at the University of Toronto and Harvard Medical School — with a growing network of clinical and scientific advisors.
