OpenEvidence vs Vera Health (2026)
Both are free to verified clinicians and both search the published literature before answering.

Vera Health is built retrieval first. It searches a corpus given as more than 60 million papers, guidelines and care pathways, grades the evidence, then writes a short cited answer. ACEP clinical policies sit inside it under a March 2026 partnership. The choice turns on evidence and paperwork. Outside researchers have studied OpenEvidence, while every figure Vera Health publishes is its own. Vera Health publishes its business associate agreement in full; OpenEvidence says it signs one and does not publish it.
