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

A large language model will answer any neurosurgical question with total confidence — and no idea whether it's right. A textbook 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 citations. Fine for a blog, dangerous in a craniotomy decision.
References cost you time you don't haveBetween cases, the last thing you want is ten open tabs and a paywall.
No specialty in the loopGeneral tools don't reason like a vascular neurosurgeon. Nuance is where patients 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 "unruptured 6 mm MCA aneurysm in a 54-year-old smoker, treat or observe?" 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 neurosurgical questions, answered in the format our knowledge base speaks: answer → decision rule → what's missing → source.

Unruptured intracranial aneurysm — treat or observe?

For most incidental aneurysms <7 mm in the anterior circulation without prior SAH, observation with interval imaging is reasonable; size, location, growth, and patient factors shift the balance toward treatment.PHASES · UIATS

Decision ruleWeigh rupture risk (PHASES) against procedural risk. Posterior circulation, prior SAH, documented growth, or younger age push toward securing the aneurysm.

Missing data: exact size & morphology, location, family history, and smoking status change this recommendation.

Grounded in specialist-authored, cited knowledge — red-penned by Dr. Sérgio.

Chronic subdural hematoma — operate, or manage conservatively?

Symptomatic cSDH with significant thickness or midline shift is typically drained (burr-hole with a subdural drain reduces recurrence); small, minimally symptomatic collections can be observed, and middle meningeal artery embolization is an emerging adjunct.guideline synthesis

Decision ruleSymptoms + radiographic burden drive surgery; a post-op subdural drain is favored to cut recurrence. Reserve conservative management for thin, asymptomatic collections.

Missing data: GCS, membrane/septation, anticoagulation status, and functional baseline change the plan.

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. Neurosurgery is the first specialty, led by vascular neurosurgeon Dr. Sérgio Tadeu Fernandes, who red-penned the knowledge base. 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.
