The intelligence
behind your care

ERO is the AI at the center of Sumero. Not a chatbot you argue with, not a search engine that guesses.

ERO knows your history, keeps your labs and wearable data in one place, and connects you to your care team the moment you need a person. The intelligence handles the busywork. Your physician makes the decisions.

Knows your full picture

ERO connects to your records, labs, and wearables, so everything is based on you, not generic inputs.

Connects you to care

When something needs a clinician, ERO brings your care team into the conversation instead of leaving you at a dead end.

Always on

Available 24/7, so you're never waiting for business hours just to get organized or pointed in the right direction.

Private and secure

HIPAA-compliant, encrypted, and never sold. Your health data stays yours.

Learns over time

ERO keeps the thread between visits, so your care builds on everything that came before instead of starting over.

Responsible Medical AI

Built to a higher standard

Healthcare AI has to clear a higher bar than a consumer chatbot. ERO is designed around the principles regulators and clinicians are converging on for responsible health AI.

Responsible by design

Physicians safeguard every interaction. ERO works inside defined limits and never makes a clinical decision on its own.

Evidence-grounded

Built on clinical guidelines and vetted medical sources, not the open internet, so what you learn is accurate and current.

Context-aware

Connected to your records, labs, and wearables, so ERO understands your full history, not just what you typed today.

Built-in safeguards

ERO is built to flag urgent or uncertain situations and hand you off to your care team quickly, rather than guessing.

Transparent and traceable

Every interaction is logged and reviewable, aligned with the emerging CHAI and Joint Commission standards for responsible health AI.

Private and secure

HIPAA-compliant and encrypted. Your health data stays yours, and is never sold.

The line that matters

ERO educates and organizes. It does not diagnose, interpret your individual results, or give medical advice. Every clinical decision is made by a licensed clinician, and when ERO is unsure, it defers to your care team. By design.

Care that knows you, backed by real physicians

Start membership

Physician-led. ERO organizes your information and helps point you to the right care. Your clinician interprets your results and makes the medical decisions. Sumero provides longevity and consultative care and does not replace your primary care physician.
