OpenEvidence vs Vera Health
Both are free to verified clinicians and both search the published literature, so the comparison turns on evidence and on paperwork. OpenEvidence has the evidence: eleven independent studies in two years, named partnerships with the New England Journal of Medicine, JAMA and Cochrane, and Epic embedding at named health systems. Every number Vera Health publishes about itself is vendor generated, including a licensing examination score that tells you about examinations rather than about bedside answers. Vera Health has the paperwork: the full text of its business associate agreement published publicly and dated, an explicit statement that personal data does not train its models, and United States hosting stated in the privacy policy. That combination is rare here and it matters more than it looks, because a free product without an agreement cannot legally carry patient detail. Use OpenEvidence for reach and scrutiny, Vera Health where contracting is the obstacle.
- The evidence position is the deepest in this category and none of it was commissioned: a systematic review following PRISMA identified eleven independent studies evaluating this product between 2024 and 2026.
- Named partnerships with the New England Journal of Medicine, JAMA and its eleven specialty journals, and Cochrane Systematic Reviews, plus enterprise Epic embedding documented at Mount Sinai across seven hospitals.
- Two answer modes for two different questions, a short cited answer in seconds for the point of care and a longer research mode for a question that deserves it.
- The full text of its business associate agreement is published at a public address and dated, which is the strongest posture on that axis in this segment and something a buyer can read before entering a sales process rather than after.
- The architecture is retrieval first by design and the company says so, searching a corpus given as more than 60 million peer reviewed papers, guidelines and care pathways, ranking and grading before generating rather than generating and then citing.
- The privacy position is explicit rather than implied: personal data is stated not to be used to train its models, and services are stated to be hosted and operated in the United States.

Every performance figure Vera Health publishes is vendor generated and none is peer reviewed, including a 97.5 percent licensing examination score and a benchmark result, which measure examination performance rather than answer quality at the bedside. No electronic health record integration claim of any kind appears on Vera Health's own material, so this is a browser and mobile product rather than a workflow one.
OpenEvidence is funded by pharmaceutical and medical device advertising presented alongside clinical answers, governed by a published advertising policy that should be read before accepting the arrangement. Neither vendor publishes a bias or subgroup performance analysis of its generative layer.
