OpenEvidence

What it does

OpenEvidence helps clinicians research medical questions using AI-generated answers grounded in medical literature. Users enter a question, then review a response and its cited sources. Its licensed content includes clinical findings, figures and tables from publishers such as the New England Journal of Medicine, JAMA Network and Nature Portfolio, alongside other medical reference material.

The service supports both quick reference questions and more detailed evidence reviews. Clinicians can choose a faster response or a deeper investigation, and some modes ask for further clinical context before weighing the literature. The web service and iOS and Android apps provide access to the same product, making it possible to continue research across devices.

OpenEvidence is intended for verified clinicians rather than general consumer diagnosis. The company describes access as free for verified clinicians; users must complete its eligibility process. Generated summaries still need professional review of the cited evidence and the clinical context. Separate research-preview models have restricted access and should not be assumed to be included in an ordinary account.

What it can do

• Answer clinical reference questions with citations to medical literature
• Surface licensed journal findings, figures and tables
• Choose between faster answers and deeper literature investigations
• Ask clarifying questions and incorporate clinical context in supported research modes

Example workflows

Review evidence for a clinical question

Illustrative example. Enter a clinical reference question, read the generated summary and open its citations. The output is a set of sources and an evidence summary for professional review.

Investigate a complex question

Illustrative example. Choose a deeper research mode, provide relevant context when prompted and inspect the resulting synthesis. Use its linked literature to check the reasoning and identify further reading.

Before you choose

• Answers are AI-generated search results for information purposes and are not medical advice or a diagnostic guarantee; clinicians should verify against primary sources.
• Free access is stated for verified clinicians; general consumer access terms were not confirmed.
• Darwin is in research preview by application only and is not part of the general product.
