Medical AIMedical AI vs OpenEvidence.
Both reason the evidence through the specific case and cite every claim. The differences that matter in practice are the built-in calculator suite, who is allowed to use it (Medical AI opens to students and residents, not only verified clinicians), and one subscription that follows you across web and iOS.
OpenEvidence is a strong, well-resourced answer engine and free to the clinicians it verifies. Choose Medical AI when you want 40+ validated calculators next to the answers, when you are a student or resident shut out by a verification wall, or when you want a single subscription across web and iOS. Both reason about the case and cite their sources, and both are references, not a substitute for clinical judgement.

The honest summary
OpenEvidence is a serious product. Like Medical AI, it reasons the evidence through the specific case and returns a cited answer, it is free to the clinicians it verifies, and it is backed by real medical-publishing partnerships. On the core job of answering a clinical question well, the two are genuinely comparable.
Medical AI competes on what surrounds the answer: 40+ validated calculators next to the engine, a curated library, one subscription linked across web and iOS, and open access for students and residents rather than verified clinicians only. It is a premium tool, used daily by clinicians across the US, Canada, and Europe, that simply does not gatekeep who can use it.
Open to the whole team
OpenEvidence verifies that you are a licensed clinician before it will answer. That is a defensible design choice, but it locks out medical students and residents early in training, the people learning the evidence in the first place. Medical AI makes the opposite choice: the same reasoned, cited answers are available to attendings, residents, and students alike, with no verification wall to clear before your first question.
Answers, calculators, and a library in one place
Both tools answer clinical questions well and tailor the answer to the case you describe. Medical AI adds the parts of the day that are not prose: 40+ validated calculators (Wells, A-a gradient, corrected QT, BMI, creatinine clearance, and more), each with its formula and sources shown, plus a curated reference library for the questions clinicians search most. One tool covers the look-up, the math, and the read.
One subscription across web and iOS
Medical AI's subscription is account-bound, not device-bound. Buy Pro on iOS and the web unlocks for the same login; subscribe on the web and the app honours it, with no double billing. Pricing is public at $20 a month or $180 a year, and a free daily tier lets you judge the answers and their citations before paying.
