§ 01 · Demonstration

A real answer, with the citations it rests on.

A sample question on co-prescribing, composed with the same rules the app uses: a synthesized reply with its citations rendered inline, the way you would see them in a real session.

medicalaiapp.com/chat/co-prescribing-metformin-lisinopril
Is it safe to co-prescribe metformin and lisinopril in a 67-year-old with T2D, stage 2 CKD, and well-controlled hypertension? What should I monitor?

Drug interaction profile

Metformin and lisinopril are co-prescribed routinely in patients with type 2 diabetes and hypertension. The clinically meaningful interaction is hemodynamic, not pharmacokinetic - additive risk of acute kidney injury when intercurrent illness or volume depletion is layered on top.[1]

Guideline[1]
KDIGO 2022: Diabetes Management in CKD
Kidney Disease Improving Global Outcomes·2022·Practice Point

Mechanism

Lisinopril reduces glomerular filtration pressure; metformin is cleared renally. A drop in eGFR therefore raises metformin exposure, increasing lactic-acidosis risk in the presence of hypoperfusion.[2]

Research[2]
Association of metformin use with risk of lactic acidosis across the range of kidney function: a community-based cohort study
JAMA Intern Med·2018·Lazarus et al.·Evidence: Moderate

Monitoring

Check eGFR within 1–2 weeks of starting or up-titrating either drug; hold both during acute illness with volume loss. Dose-reduce metformin when eGFR is 30–45 mL/min and discontinue below 30.[3]

§ 02 · How it works

Three steps. Nothing performed for the room.

01 - Ask

State the clinical question.

Type it the way you'd ask a colleague - long-form, specific, with the patient's relevant context.

02 - Look up

Sources are pulled, not invented.

The system retrieves from peer-reviewed journals, society guidelines, FDA labels, and indexed clinical references before composing a reply.

03 - Verify

Every claim is traceable.

Citations sit inside the answer, not under it. Tap any one to open the source. Disagree with anything? The page is right there.

§ 03 · The corpus

Where the citations come from.

A non-exhaustive index of the source types Medical AI consults when composing an answer. Each citation in a response carries the source name, publication year, and the evidence grade where one is available.

§ The difference

Why not just ChatGPT?

A general chatbot

Generates fluent text from memory. It will invent a citation as readily as a fact, and it cannot reach the journals and guidelines that sit behind paywalls.

Medical AI

Retrieves first - from peer-reviewed research, society guidelines, and FDA labels - then composes an answer where every claim links to the page it came from. You read the source, not a paraphrase. When the evidence is thin, it says so.

§ 04 · In use

Two moments in a working day.

Between patients

The 60-second look-up.

A finding you don't recognize on a chart. An interaction warning the EMR flagged but didn't explain. A pediatric dose you want to triple-check. Open Medical AI, ask, scan, judge. Three citations and you're back in the room.

Typical session~60s
Case write-ups

The long, considered pull.

A complex presentation that needs a literature scan. An off-label decision you want to defend in the chart. A new guideline you want to read through the lens of your patient. The system stays in the conversation as you narrow the question.

Typical session~20m
§ 05 · A note on what this is not
Medical AI does not perform empathy. It does not say "great question". It does not celebrate. It looks up - across thousands of sources - and shows you the page it found.

§ 08 · Frequently asked

The questions people ask first.

How is this different from ChatGPT or Gemini?

General chatbots generate text from memory and can fabricate citations. Medical AI retrieves from peer-reviewed research, society guidelines, and FDA labels first, then cites the exact source for each claim so you can verify it yourself. In practice that means far fewer hallucinations on clinical questions.

Can I try it before paying?

Yes. You can ask questions free every day, no card required, to judge the quality of the answers and their citations before deciding on Pro.

Is Medical AI a substitute for clinical judgment?

No. It is a reference. Every answer is intended to be read alongside its citations and judged by you. Where the evidence is conflicting or limited, the answer will say so, in proportion.

How current are the sources?

Drug labels and society guidelines are refreshed continuously from primary sources (DailyMed, NICE, USPSTF, KDIGO, AHA, IDSA, and others). The research corpus is indexed and updated; each citation shows the publication year so you can judge currency at a glance.

What happens to my queries? Are they used to train?

Your conversation history is yours. We do not train models on user chats. Account-bound history is encrypted at rest and removed on request.

I subscribed on iOS. Do I need to pay again on the web?

No. iOS Pro subscribers get web access automatically - sign in with the same account. Entitlements are linked at the account level, not the platform level.

Is this regulated as a medical device?

Medical AI is an information-retrieval and summarization tool intended for use by licensed clinicians; it is not a diagnostic device. We follow the FDA's guidance on clinical decision support software and do not provide specific patient-level recommendations.

Who builds this?

A small team of clinicians and engineers. The product is used by the team's clinical advisors daily; design decisions go through them before they ship.
