Built by clinicians

Founded by a neurosurgeon.
Validated by 1,000+ attendings.

Dr. Aaron Cohen-Gadol — recipient of the Vilhelm Magnus Medal and founder of The Neurosurgical Atlas — built AtlasGPT to close the most consequential gap in medicine: the distance between what a clinician needs at the bedside and what software actually delivers.

Not built by technologists who consulted physicians. Built by a physician, then validated by a thousand more.

The problem

The colleague you need is rarely
the colleague you have.

Three things break down at the bedside: subspecialist availability, static reference tools, and consumer chatbots that fabricate clinical facts.

01 — Coverage

The subspecialist is not always there.

12 min

Average wait for a specialist consult

02 — Reference

UpToDate is a textbook, not a colleague.

73 days

How often medical knowledge doubles

03 — Generic AI

Consumer chatbots invent clinical facts.

44%

GPT-4 misinformation rate. AtlasGPT: 14%.

35+ subspecialties

Head to head

We asked ChatGPT to grade
its own answer against ours.

One real case — 62F, metastatic lung adenocarcinoma, EGFR exon 19 deletion, brain metastases. Same prompt, both tools, side by side.

AtlasGPT: 8.5/10. My previous answer: 7/10.

— ChatGPT, scoring the comparison

Its reasoning: AtlasGPT "demonstrates deeper evidence-based reasoning and includes more trial/guideline context."

Trusted at the bedside

The only opinion that matters
is the clinicians using it.

★★★★★

It surfaced a paraneoplastic syndrome I would have worked up over three more visits. The citations sent me straight to the original NEJM case series.

Dr. Neil R., MD

Internal Medicine, PGY-4 · Academic medical center, Midwest

★★★★★

On nights, I am the most experienced person in the unit. Having a subspecialist I can hand a case to at 3am has changed how I practice.

L. Dempsey, RN, CCRN

Critical Care · Single-center Level 1 trauma center, Northwest

★★★★★

It does not hallucinate. When I push it, it tells me what it doesn't know and points me to the literature. That is the bar.

Dr. J. Reyes, DO

Infectious Disease · Urban public clinic, West Coast

How it works

From question to cited answer
in under a minute.

01

Ask in plain language

Describe the case the way you'd describe it to a colleague. No syntax, no training, no IT involvement.

02

It reasons across specialties

Your question routes to a specialty-trained agent, which consults adjacent specialties and works the differential against 10M+ peer-reviewed sources.

03

You get an auditable answer

Ranked differential, inline peer-reviewed citations, and next-step recommendations — with the reasoning trace shown, so you can check the logic before you act on it.

The platform

Not a chatbot.
It's your
Clinical reasoning partner.

AtlasGPT runs on an agentic architecture: specialty-trained reasoning agents that route, deliberate, and cite — the way a multidisciplinary team works a tumor board.

Specialty-trained agents

Depth you'd normally only find in an attending in that field, not a single general-purpose model.

Inline peer-reviewed citations

Every clinically meaningful claim links to its source: NEJM, Lancet, JAMA, Cochrane, specialty society guidelines.

Reasoning trace, not a black box

You see the differential, the elimination logic, and the confidence in the lead diagnosis.

Refuses to hallucinate

When the evidence is thin, it says so and points you to the literature instead of inventing an answer.

Questions clinicians ask
before they subscribe.

AI hallucinates — how can I trust it clinically?

Every claim carries an inline peer-reviewed citation and a visible reasoning trace. When evidence is thin, it says so rather than inventing an answer. AtlasGPT's misinformation rate is 14%, against 44% for GPT-4 and 68% for Gemini Advanced.

What about liability?

AtlasGPT is decision support, not a decision. It produces audit-ready documentation of the evidence behind your reasoning — the same relationship you already have with UpToDate.

Is patient data safe?

Case content is processed with zero data retention — it isn't stored after your answer is generated, and it's never used to train models, sold, published, or shared. On individual plans AtlasGPT is not a HIPAA covered entity or business associate, so describe cases in de-identified terms rather than entering protected health information. HIPAA-ready infrastructure is available on Enterprise — contact sales for institutional deployment.

I already have UpToDate.

78% board-exam accuracy against UpToDate's 74%, at a lower monthly cost — and it adds 35-specialty consults and reasoning traces UpToDate doesn't offer.

Will this slow my workflow?

No training, no IT, no EHR integration required. Conversational interface, productive in minutes, works on phone or desktop.
