AI Editor ApprovedApproved and published by our AI Editor-in-Chief after full panel analysis.OpenEvidence is an AI-powered medical search and clinical decision support platform for verified U.S. healthcare professionals. Physicians, nurse practitioners, and medical students use it to answer clinical questions with responses grounded in peer-reviewed literature from NEJM, JAMA Network, NCCN, Cochrane, and more than 300 journals. Access is free for U.S. clinicians verified through an NPI number; revenue comes from pharmaceutical and device advertising rather than user subscriptions. Core capabilities include cited answers that link every claim to its source, the DeepConsult research agent that cross-references hundreds of studies and returns a report within hours, Visits for turning patient encounters into evidence-enriched notes, and AMA PRA Category 1 CME credit earned while researching. It is the best fit for clinicians who want point-of-care answers on web, iOS, or Android without paying for a reference subscription. Alternatives include UpToDate, Doximity GPT, and Glass Health.
OpenEvidence works like a search engine built for the clinic: a physician types a question about diagnosis, drug dosing, interactions, or treatment options and receives a synthesized answer in which every claim carries an inline citation linked to the underlying peer-reviewed source. Answers draw on more than 300 medical journals plus FDA and CDC materials, and users can ask follow-up questions in the same thread. Full access requires verification with a U.S. National Provider Identifier, while medical students can register with school credentials.
Two flagship capabilities extend the core search. DeepConsult is a research agent that autonomously analyzes and cross-references hundreds of peer-reviewed studies in parallel and returns a comprehensive research report within hours; it is included free for all verified U.S. clinicians. Visits transcribes patient encounters and generates clinical documentation enriched with guideline-based evidence. The platform also emails update alerts when new evidence changes the answer to a previously asked question, and verified NPI users earn AMA PRA Category 1 CME credit as they research.
OpenEvidence is aimed at U.S. physicians, nurse practitioners, physician assistants, and medical students; by December 2025 it counted 760,000 registered U.S. physicians running roughly 18 million clinical consultations per month. It is free for verified clinicians, with revenue coming from advertising rather than subscriptions, which sets it apart from paid references such as UpToDate and from other clinical AI tools like Doximity GPT and Glass Health.
The platform runs on the web and in free iOS and Android apps that include Home Screen and Lock Screen widgets for point-of-care use. Its answers are grounded through content partnerships with the American Medical Association, the New England Journal of Medicine, all eleven JAMA specialty journals, and the National Comprehensive Cancer Network, and the same engine powers Elsevier's ClinicalKey AI.

Full free access for U.S. healthcare professionals verified via NPI, funded by advertising rather than user fees.
Free for clinicians, backed by a $12 billion vendor; the governance question is yours to write.
“OpenEvidence is free for NPI-verified clinicians and closed a $250 million Series D in January 2026. The real board decision is governing an ad-funded tool your medical staff will use regardless.”
No purchase order anywhere in this decision. OpenEvidence is free for NPI-verified clinicians, funded by advertising, and it never touches your budget. It reaches your medical staff regardless.
Viability isn't the worry here. They closed a $250 million Series D in January 2026 at a $12 billion valuation, and the licensed NEJM and JAMA corpus is a moat UpToDate has to take seriously. DeepConsult — their autonomous research agent — ships free to every verified U.S. clinician, and usage runs around 20 million consultations a month.
The catch: you're not the customer — pharma advertisers are, and the board should hear that framing before anyone blesses it. My call: sanction it now, write the ad-governance policy this quarter, and put a renewal-style review on the calendar for month 12.
Free, cited, and licensed against UpToDate's $579-per-seat paywall is a strong position.
Licensed NEJM and JAMA content is defensible, but pharma ad adjacency invites scrutiny.
Free access with NPI verification means value lands the day a clinician signs up.
Point-of-care evidence quality advances care delivery rather than just trimming reference spend.
A $250 million Series D at a $12 billion valuation in January 2026 removes runway risk.
Health-system leaders who want sanctioned point-of-care AI without a procurement cycle.
Executives who only sanction vendors they can hold to an SLA.
Licensed NEJM and JAMA grounding makes this defensible point-of-care AI, once ad governance is written.
“Licensed content from NEJM, JAMA, and NCCN gives OpenEvidence the provenance story point-of-care AI has lacked. The ad-funded model and the missing EHR integration are the governance work left to the health system.”
A hallucinated dose recommendation is a patient-safety event, not a product bug, so provenance decides this entire evaluation. OpenEvidence pins every claim to inline citations across 300-plus journals, under licensed NEJM, JAMA, and NCCN content — licensed, not scraped, which is what I can defend to a P&T committee.
The long-term implication sits in Visits, the ambient-documentation layer: it moves the platform from lookup into the note itself, territory where health systems already hold scribing contracts with Abridge or Nuance DAX. Integration surface is the weak point — it runs beside Epic, not inside it, so every query is a separate pane of glass.
However, advertising funds the whole thing, and pharma promotion adjacent to clinical answers demands a formal conflict-of-interest policy before any system-wide endorsement. Write it now — with a reported 40% of U.S. physicians already using the platform daily, it's inside your walls either way.
It defined the free, citation-grounded point-of-care category and powers Elsevier's ClinicalKey AI.
Inline citations to licensed NEJM, JAMA, and NCCN content match how clinical evidence must be defended.
No native EHR integration; it runs beside Epic as a separate pane.
Ad funding and content-license renewals are structural dependencies to govern.
DeepConsult and Visits extend the platform well beyond a lookup box.
CMIOs who need citation-level provenance in point-of-care AI.
Health systems that require native EHR integration from day one.
UpToDate money buys what OpenEvidence gives away, but you hold no contract and no leverage.
“The all-in license cost is zero for verified U.S. clinicians, with DeepConsult and CME credit included. The real spend is governance time, because there is no contract to stand on.”
A 500-physician system paying UpToDate list price spends about $290K a year on clinical lookup — $579 a seat, every seat, every year. OpenEvidence prices the identical job at $0. Ad-funded, NPI-verified, one plan, no tiers.
What's bundled matters more than the sticker. DeepConsult, their research agent, comes included; UpToDate sells nothing comparable, and Doximity GPT is free without the licensed journal corpus. CME credit accrues as physicians search — AMA PRA Category 1 — offsetting stipends you already pay.
But there's no contract, no SLA, no leverage. Advertising funds it today; a repricing to subscriptions later would find you with nothing in writing. Budget zero dollars and serious governance hours — the Visits documentation feature touches PHI, and that review is real work.
Nothing to invoice, but the Visits PHI review still consumes procurement hours.
No term, no auto-renewal, no exit penalty — because there is no contract at all.
One plan at $0 with no quote-only tiers or hidden add-ons.
Direct subscription displacement plus CME offset makes the math immediate.
Displaces roughly $290K a year of UpToDate spend for a 500-physician system.
Finance teams who want to retire per-seat reference subscriptions.
Procurement teams that need signed terms behind every clinical tool.
Cited answers fast enough for the minute between patients, though it still lives outside Epic.
“Plain-language questions come back with tappable citations at ward pace, and DeepConsult handles the deep dives. Everything still happens outside the EHR, which keeps each lookup a context switch.”
The real spec on the wards is the ninety seconds between patients, and cited search is the only feature that matters at that speed. A plain-language question — renal dosing, bridging anticoagulation, an ugly drug interaction — comes back synthesized, with each claim tappable through to the journal source.
The Lock Screen widget is the sleeper feature; rounding happens on a phone, and UpToDate's app was never built for that pace. DeepConsult covers the other mode — queue a hard question at sign-out and a report cross-referencing hundreds of studies lands within hours. Follow-up questions stay in one thread.
Nothing here lives inside Epic, but that's the real limitation — every lookup is a context switch out of the chart, and a Visits draft needs the same read-before-sign scrutiny as any scribe note. Free with AMA Category 1 CME attached — for daily inpatient questions, hard to beat.
A plain-language search box with citations fits ward pace immediately.
Visits drafts evidence-enriched notes that still need read-before-sign review.
One-time NPI verification is the only real hoop in daily use.
DeepConsult and threaded follow-ups reward heavy daily use.
Widgets and mobile apps fit rounding, but every query leaves the EHR.
Hospitalists who need cited answers between patients.
Clinicians who practice outside the United States.
A search box that respects a clinician's hurry, with the ad question hanging over year three.
“NPI verification is the only hoop, and after it the product is a search box with unusually thoughtful touches. Ad-supported is the asterisk on an otherwise free and polished tool.”
Signing up wants your NPI number, not just an email, and that gate is quietly the whole point — everything inside assumes you're a clinician in a hurry. Past it, the product is a search box. No template gallery, no settings maze, nothing to configure.
The touches are right. A Lock Screen widget makes a lookup one tap, and Answer Update Alerts email you when new evidence changes something you asked months ago — the kind of feature nobody demos and everybody ends up loving. Doximity GPT is free too, but it never follows up on your old questions.
The tradeoff is the business model: ads pay for all of this, and ads have a way of getting louder as the years go by. For now it's free, hands out CME credit for reading, and over 750,000 U.S. physicians have signed on — tools this unfussy don't stay secret.
Widgets, threaded questions, and update alerts show real daily-use care.
It is a search box in plain language; there is nothing to learn.
Full iOS and Android apps with Lock Screen widgets beat the category norm.
NPI verification is a hoop, but a one-time one with full access after.
No public status page cited, but the scale of daily clinical use suggests stability.
Busy clinicians who want lookup speed with zero setup.
Non-clinical users who cannot pass NPI verification.
Real journals and real usage, but the ad-funded model deserves more scrutiny than the valuation got.
“The content partnerships and usage numbers verify, which is rarer than it should be. The advertising engine and a valuation that ran from $1 billion to $12 billion in eleven months are what I'd watch.”
Eleven months took this valuation from $1 billion to $12 billion. Prices like that get paid for stories, and stories need endings that haven't been written yet. So: what's real?
More than I expected. NEJM, JAMA, and NCCN license content here — journals of that caliber don't sign with vaporware. Usage checks out too: a reported 1 million consultations in a single day by March 2026. And exit is painless; it's free, so you walk whenever.
The yellow flag is who pays. Pharma advertising sits under a clinical answer box, and that incentive deserves more sunlight than it gets. DeepConsult is genuinely differentiated — UpToDate has no answer for it — but if the ad model wobbles, 'free' is the first promise renegotiated.
Licensed journals plus DeepConsult is real, but generalist AI keeps closing in.
Free with no contract or data hostage means leaving costs nothing.
An ad-funded clinical model at a $12 billion valuation has not yet survived a stress test.
'America's Official Medical Knowledge Platform' is a self-granted title atop otherwise verifiable claims.
