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.

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.

24 hours

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.

How it works

From question to cited answer
in seconds.

Ask in plain language

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

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.

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.

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."
