Functional medicine is guessing.
You deserve diagnostic logic.
You've spent thousands on practitioners who order random tests and make assumptions based on rodent studies. There's a better way.

"The standard functional medicine model is to come up with some plausibility, overstate limited data, and jump from preclinical preliminary evidence to clinical decision-making."

"Functional medicine is very very soft science. Often not valid science at all. Lots of assumptions based on rodent studies and test tube studies."

Hospital-grade diagnostic reasoning,
for your chronic symptoms.
The same systematic approach an ER physician uses — applied to the chronic conditions that conventional medicine dismisses.
🔍

Structured Investigation

Guided symptom questionnaires designed by an ER physician. We ask the questions your functional practitioner forgot.

🧪

Lab Integration

Upload your existing lab results. Our AI identifies what's been tested, what's missing, and what to order next — systematically.

🤖

Differential Diagnosis Engine

AI generates a ranked list of possible root causes based on your complete clinical picture — not just the latest supplement trend.

📊

Evidence Ratings

Every recommendation rated by quality of evidence. Know the difference between "proven in humans" and "worked in mice."

📋

Investigation Plans

Personalized step-by-step investigation plans that systematically narrow down your root cause — no shotgun testing.

From scattered testing to systematic diagnosis.
Logical, evidence-based, step by step.

Treatment Roadmap

Evidence-rated treatment recommendations with clear next steps and monitoring plans.

Real medicine. Not functional guessing.
🩺

ER Physician-Designed

Built by a doctor whose specialty is rapid, systematic diagnosis under pressure. That logic now works for your chronic symptoms.
