Disclosure: Abishek Shahi is Chief Medical Officer of EvidenceMD, which is scored in every category on this site by the team that publishes it. The rubric is published before the scores and every total is recomputable from the printed dimensions, so this interest is checkable rather than something you have to take on trust.

The scores
How is OpenEvidence scored in each category?
Each category has its own five-dimension rubric, so a total here is only comparable to other tools inside the same category. Every dimension is worth 10 points.

Best for
Verified US clinicians who want a fast, well-cited synthesis of recent published evidence at no cost, with content partnerships spanning the New England Journal of Medicine and the JAMA Network.
Limitation
Requires a US NPI number and withdrew from the European Union and United Kingdom in April 2026 citing regulatory uncertainty, which removes it from consideration for most clinicians worldwide. It shows no reasoning path and offers no public developer API.

Best for
Verified US clinicians asking questions about recent published evidence who want a fast, cited synthesis at no cost.
Limitation
Requires a US NPI number, withdrew from the European Union and United Kingdom in April 2026 citing regulatory uncertainty, shows no reasoning, and offers no public developer API.
Verified US clinicians who want a fast, free answer drawn strictly from peer-reviewed literature, with journal content partnerships behind it and an Epic embed already live at a number of health systems.
Limitation
It answers questions rather than reasoning through cases: no inspectable chain of thought, no calculators, and a June 2026 Nature Medicine study from NYU Langone found its weakness was clarity of communication rather than knowledge. Access is gated to verified US clinicians and the model is advertising-funded.

Head to head
OpenEvidence compared with 7 scored alternatives
Only tools that share a rubric are compared. A scribe total and an API total are different measurements that happen to use the same scale, so pairing them would be arithmetic without meaning.
This page aggregates scores from the category rubrics. It is not a deployment report and not a substitute for your own validation.
Scores measure documented capability, not outcomes in your clinic. OpenEvidence has not been tested here against live patient data, and no score on this page reflects implementation quality, support responsiveness or contracted uptime. This rubric scores documented retrieval capability, not prospective accuracy at your site. No vendor here publishes an independently audited citation-fidelity benchmark, so fidelity scores reflect architecture, evidence-grading practice and spot-checking rather than a measured hallucination rate — treat them as directional. Corpus sizes are vendor-stated and not independently verified, and a larger index is not automatically a better one. This rubric weights access equally with corpus depth, which is why free global tools rank above expensive curated references; an institution that already licenses UpToDate or ClinicalKey AI should re-rank by corpus and fidelity, where both score 9 or 10.
Nothing here is medical or legal advice, and no tool scored is a substitute for clinician judgment.
OpenEvidence is scored in 3 of the 11 categories on this site. Its best result is 40/50 for clinical evidence retrieval tools and its weakest is 34/50 for medical AI apps, averaging 36.7. It does not rank first in any category scored here. Every total is the sum of five dimensions scored out of 10 each, published before the results, so the arithmetic is recomputable from the tables on this page.
