Best medical AI for physicians with every plan priced

The best medical AI for a physician depends on the job: free OpenEvidence and ChatGPT for Clinicians for questions, Glass Health from $90 a month for scribing, ClinicalKey AI and Dyna AI for an edited reference, and a separate check at the moment of prescribing. Every price, read at the vendor.

Decision-support check

Press Run check for the interaction, contraindication, dosing and alternatives on this pair.

That was your demo check, run on the same references the desk uses. The desk adds renal dosing against an estimated clearance, hepatic review, unlimited checks, saved history and your sign-off on every card.

Not in the on-page check

The on-page check covers five prescribing scenarios and never invents clinical output, so it will not produce a card for this pair.

The full Prescriber.io desk checks any regimen against interactions, contraindications, and renal or hepatic dosing, with cited sources for you to verify.

In short

The best medical AI for a physician depends on the job. For clinical questions, OpenEvidence and ChatGPT for Clinicians are free for verified US clinicians. For documentation, Glass Health pairs an ambient scribe with AI reasoning at $90 a month on Pro ($81 billed yearly). For an edited reference with AI, ClinicalKey AI costs $349 a year and DynaMedex with Dyna AI $675. None of them checks a full medication list at the moment of prescribing; a prescribing checker such as Prescriber.io does that from $24 a month billed yearly.

The best medical AI for a physician depends on which of four jobs you are paying it to do: answer clinical questions, write the note, give you an edited reference with an AI front end, or check the prescription you are about to sign. No single product does all four well. The two strongest question-answering tools cost nothing once you verify, so the money decision is really about the other three.

We priced every tool below at the vendor's own page in October 2026, except ChatGPT for Clinicians, read in September. Where a vendor publishes no price, we say so instead of repeating a number from a software directory.

Which AI should a physician use for clinical questions?

Start with the free ones. OpenEvidence answers clinical questions with citations to the literature and is free for verified US healthcare professionals, with no premium plan behind it. ChatGPT for Clinicians launched free for verified US physicians, NPs, PAs and pharmacists, cites its sources and lets an individual sign a BAA. For background reading and "what does the evidence say" questions, paying for a third tool rarely adds much.

The catch is that free access is a permission rather than a contract. Both are funded by someone other than you, and the terms can change on the vendor's schedule. We go through what that means for a practice in OpenEvidence cost and pricing, and compare the two free options directly in OpenEvidence vs ChatGPT for Clinicians.

Is Glass Health worth paying for?

Glass is worth paying for when documentation is your bottleneck. It is the only tool on this list that listens to the visit and drafts the note, and every paid plan pairs that scribe with AI clinical reasoning. Pro at $90 a month, or $972 a year billed yearly, removes the ads and adds the advanced model. Max at $200 a month is the only tier with EHR integration, listed for Athena, Epic, eCW and Elation.

It is a weaker buy if your notes are already handled by a scribe or your health system's own tool, because the scribe allowance is a large part of what each tier charges for. We lay out every plan and the yearly math for a small practice on our Glass Health pricing page.

When does an edited reference with AI beat a free chatbot?

When you need to defend a decision. ClinicalKey AI at $349 a year answers from Elsevier's journals and books, offers a 14-day free trial on individual plans, and can be paid at $39 a month if you would rather not commit (see ClinicalKey AI pricing for the resident rate and the trial terms). DynaMedex costs $599 a year, or $675 with Dyna AI, and bundles Micromedex drug content, which matters if you also want a drug reference. ACP members get DynaMedex with Dyna AI included in their dues, so check that before you buy anything.

UpToDate remains the reference many physicians trained on, but Wolters Kluwer publishes no individual price, so you only see it in the store after picking your role. Our UpToDate subscription cost guide covers what you can learn before checkout, and DynaMed vs OpenEvidence covers whether a $599 renewal still makes sense next to a free answer engine.

What medical AI checks prescriptions for interactions and dosing?

None of the chat-style tools above do this the way a prescribing checker does. A question-answering AI responds to the question you type. At the moment of prescribing you face several questions at once: does the new drug interact with anything on a fourteen-item list, is it contraindicated by a diagnosis or an allergy, and does an eGFR of 34 change the dose. Typing each of those into a chat window is slow, and the one that gets skipped is the one nobody thought of.

Prescriber.io runs all of those checks on the actual medication list every time. It flags interactions and contraindications, surfaces renal and hepatic dose adjustments, suggests guideline-based alternatives and cites the source for each card, and you review and sign off. It does not write notes or answer open-ended questions, which is why it costs $24 a month rather than $90. The drug contraindication checker page shows how the contraindication side works.

What is the best AI setup for a physician in private practice?

For most independent physicians the sensible stack is two or three tools, not one. Use a free evidence engine for questions. Add Glass Pro only if documentation is eating your evenings. Add a prescribing checker so interactions, contraindications and renal dosing are checked on every list rather than only when you remember. A physician running all three would pay about $1,260 a year: $0, plus $972, plus $288.

If you sign BAAs with several AI vendors, keep them somewhere you can find them at renewal time. A simple contract management software setup that tracks expiry dates saves the scramble when an auditor or a payer asks which vendors touch patient data. For a physician employed by a health system, the first step is cheaper still: ask what the system already licenses before paying personally for anything on this list.

Are medical AI tools HIPAA compliant?

Several now offer a Business Associate Agreement, including OpenEvidence, Glass Health and ChatGPT for Clinicians at the individual level. A vendor offering a BAA and your employer permitting PHI in that tool are separate questions, and some health systems still tell staff not to enter patient details into a personal AI account. Read your own policy before you rely on the vendor's announcement.

How to choose without wasting a year of subscription fees

  1. List what your employer and societies already pay for. ACP includes DynaMedex with Dyna AI. Many hospital libraries license UpToDate and ClinicalKey.
  2. Name the job you are short of. Questions, notes, an edited reference, or prescribing checks. Buy for that job only.
  3. Use the trials. ClinicalKey AI gives individuals 14 days, and the trial rolls into a paid plan unless you cancel. Glass has a free Lite plan to test the interface before you pay for Pro.
  4. Price the year, not the month. Glass and ClinicalKey both charge more month to month. Annual billing saves 10 percent on Glass and about 25 percent on ClinicalKey AI.

If prescribing safety is the job you are short of, see our per-clinician pricing and try the checker on a real medication list.

Frequently asked questions

What is the best medical AI for physicians?

There is no single best one, because the tools do different jobs. OpenEvidence and ChatGPT for Clinicians are the strongest free options for clinical questions. Glass Health is the pick if you also want an ambient scribe. ClinicalKey AI and DynaMedex with Dyna AI suit physicians who want answers drawn from an edited reference.

Which medical AI is free for doctors?

OpenEvidence is free for verified US healthcare professionals with no paid tier, and ChatGPT for Clinicians launched free for verified US physicians, NPs, PAs and pharmacists. Glass Health also has a free Lite plan, but it carries ads and limited usage and is labeled for students.

How much does Glass Health cost for physicians?

Glass Health charges $20 a month for Starter, $90 for Pro and $200 for Max, per license, or $18, $81 and $180 a month billed yearly. Pro is the ad-free plan aimed at board-certified clinicians. Max adds EHR integration for Athena, Epic, eCW and Elation.

How much is ClinicalKey AI?

ClinicalKey AI costs $349 a year or $39 a month for an individual US clinician, with a 14-day free trial that converts to a paid plan unless you cancel. The annual plan works out about 25 percent cheaper than paying monthly, and residents pay $19 a month or $199 a year.

Can medical AI check drug interactions and renal dosing?

Chat-style medical AI answers the question you type, so it only checks an interaction if you ask about it. A prescribing checker runs interactions, contraindications, allergies and renal or hepatic dose rules on the full medication list every time, and shows the cited source for each flag so you can review it before signing.

See Prescriber.io check a prescription

The assistant surfaces interactions and contraindications for review, flags renal and hepatic dose adjustments, and suggests guideline-based alternatives with cited sources. You review, verify and sign every prescription.
