OpenEvidence

OpenEvidence answers clinical questions using the peer-reviewed medical literature. It is built for practising clinicians at the point of care, where the question is specific, the time is short, and an unsourced answer is worthless.

What it does

• Answers clinical questions with every statement linked to its source — trials, guidelines, and reviews
• Draws on major journals and guideline bodies through content partnerships, so the underlying corpus is authoritative rather than scraped
• Handles patient-specific framing. Questions can include comorbidities, contraindications, and demographics rather than being generic.
• Stays current, which matters because guidance changes and textbooks do not

Access and model

OpenEvidence is free for verified healthcare professionals in the United States, funded by advertising rather than subscriptions. Verification is required, which is appropriate — this is a clinical decision-support tool, not a consumer health app.

Important caveat

It supports clinical judgement; it does not replace it. Every answer is traceable to sources specifically so a clinician can evaluate the evidence themselves. It is not intended for patients seeking medical advice.
