Agentic Index
Almanac Health vs OpenEvidence (2026)
Both ground clinical reasoning in peer reviewed evidence and they act at different distances from the patient record, at 6 of 14 each.
OpenEvidence is the most widely used clinical AI platform for US physicians, with more than 757,000 verified doctors and 20 million monthly consultations, now agentic through DeepConsult multi step reasoning, trained on more than 35 million peer reviewed publications and free for verified clinicians. Almanac's Copilot acts as a level one autonomous electronic health record agent that retrieves patient data, drafts notes and places orders under clinician approval, grounded in the same kind of evidence base. OpenEvidence answers the question; Almanac acts in the chart.
Choose Almanac Health if
- Acting in the record, drafting notes and placing orders, is the capability you need.
- Patient specific reasoning over the actual chart beats general literature search.
- Clinician approval on every action is the governance model you require.
Choose OpenEvidence if
- It is free for verified clinicians, which removes the decision entirely.
- Adoption at 757,000 physicians means your clinicians probably already use it.
- Literature grounded answers are the need, and you are not ready for an agent in the chart.
