Avo vs OpenEvidence (2026)

AI Health Index verifiedSeptember 29, 2026
Verdict

Both answer a clinician's question, and they draw on different bodies of evidence. Avo is built on content rather than a model: a library of digitized medical society guidelines and calculators that health systems extend with their own protocols, with DynaMed as a named knowledge partner. Its AI works inside the record, through documented two way integrations with Epic, MEDITECH Expanse, athenahealth and Juno Health. OpenEvidence answers from the current literature under named journal partnerships, free to verified clinicians and paid for by advertising inside the product. The failure modes differ, and that is the useful part. Avo goes wrong when a guideline is superseded and the library has not caught up. OpenEvidence goes wrong when a summary reaches past what its cited source supports.

The case for Avo
  • Recommendations anchored to named society guidelines and to a health system's own protocols.
  • Documented two way integrations with Epic, MEDITECH Expanse, athenahealth and Juno Health, each saying what it reads and writes.
  • A stated SOC 2 Type II attestation, shown on every page of its site.
The case for OpenEvidence
  • Answers from the current literature under partnerships with the New England Journal of Medicine, JAMA and Cochrane.
  • Independent peer reviewed studies of its answers, where Avo's figures are its own.
  • Free use for verified clinicians, with no procurement cycle.
