What is OpenEvidence?
OpenEvidence is an AI medical information platform built for doctors and other healthcare professionals. You ask a clinical question in plain language and it returns an answer drawn from the medical literature, with citations to the studies and guidelines it used so you can check the sources yourself.
It has become widely used among US physicians, with reports of hundreds of thousands of verified clinicians signed up. Access is free for verified US healthcare professionals, and the company pays for the service through advertising and partnerships with medical publishers rather than subscriptions. Reports say it stopped serving clinicians in the UK and Europe in 2026, so check availability if you are outside the US. Independent studies have found its accuracy can drop on complex specialist cases, so it is best used as a quick evidence lookup alongside clinical judgement, not a replacement for it.
