Generic AI guesses. At the bedside, that's not good enough.

A large language model will answer any cardiology question with total confidence, and no idea whether it's right. A guideline PDF is trustworthy but slow. What you actually want is a colleague who knows the evidence cold, tells you the decision rule, and admits what they'd need to know to be sure.

Hallucination you can't auditConfident answers with invented trial citations. Fine for a blog, dangerous in a heart-failure titration.
Guidelines move faster than you can readESC and ACC/AHA update constantly; staying current between clinics is its own job.
No specialty in the loopGeneral tools don't reason like a cardiologist. The nuance is where outcomes live.

How it works

A thinking partner, not a search box. Three steps, the way you'd use a colleague.

Step 1

Ask, like you'd ask a colleague

Type or speak a real clinical question, like "new AF in a 72-year-old with CKD, anticoagulate or not?" No rigid syntax.

Step 2

Get a cited, reasoned answer

A specialist-grade answer grounded only in red-penned knowledge, with the decision rule and the specific data that would sharpen it.

Step 3

Decide with confidence

You stay the decision-maker. It carries the evidence and the caveats, so the call is yours: faster, and better defended.

The mechanism, shown — not claimed.

Real cardiology questions, answered in the format our knowledge base speaks: answer → decision rule → what's missing → source.

Heart failure with reduced EF — what's the foundational therapy?

Start all four pillars early and low-dose, then uptitrate: an ARNI (or ACE inhibitor/ARB), a beta-blocker, an MRA, and an SGLT2 inhibitor. Each independently lowers mortality in HFrEF.ESC / AHA HF

Decision ruleInitiate all four classes as tolerated rather than sequencing slowly, and uptitrate to target or maximally tolerated doses. Watch potassium, renal function, and blood pressure.

Missing data: EF, current medications and doses, eGFR, potassium, blood pressure, and symptom class change the plan.

Grounded in specialist-authored, cited knowledge — reviewed by the cardiology champion.

New atrial fibrillation — anticoagulate, and with what?

Estimate stroke risk with CHA₂DS₂-VASc and anticoagulate at ≥2 (men) or ≥3 (women). A DOAC is preferred over warfarin unless there is a mechanical valve or moderate-to-severe mitral stenosis.ESC / AHA AF

Decision ruleThe score drives the decision; when anticoagulating, default to a DOAC and dose by renal function and label criteria, not by bleeding fear alone.

Missing data: Valve status, eGFR, weight, bleeding history (HAS-BLED), and concomitant drugs change the choice and dose.

Cited, specialist-reviewed — not a generic web summary.

Why not just use OpenEvidence or ChatGPT?

All three answer questions. Only one is a specialist colleague whose every claim you can trace.

Questions physicians ask

No. It's a physician-facing clinical decision-support companion — a thinking partner for your reasoning. It does not diagnose, does not treat, and gives no patient-facing advice. The clinical decision always stays with you.

Verified physicians only. Each specialty is led by a champion physician who red-penned its knowledge base, and 30+ specialties are built. Access is gated to licensed physicians.

Every answer is grounded only in champion-authored, cited knowledge — traceable, not hallucinated. It reasons like a colleague in your specialty, and always states the decision rule plus what data is missing, instead of a confident guess.

30+ specialties are built, each with its own specialist "soul" and cited knowledge base. Neurosurgery leads; cardiology, clinical oncology, emergency medicine and intensive care follow.

It's being built now. Waitlist members get first access and the Founding Physician offer: one free month plus 50% off the first three months, and a numbered founding badge.
