What is OpenEvidence?

OpenEvidence is an AI-powered medical evidence platform that provides clinicians with research-backed answers to clinical questions. It’s a purpose-built tool for evidence-based medicine — grounded in peer-reviewed literature and clinical guidelines.

Core features:

• Clinical question answering — from research and guidelines
• Evidence citations — every answer backed by sources
• Clinician-focused — designed for professional workflows
• Free for professionals — in many regions

It addresses a real problem: the impossibility of keeping up with the medical literature, even for the most dedicated clinician.

How OpenEvidence works

The workflow fits clinical practice:

1. Ask a clinical question — natural language, medical context.
2. OpenEvidence searches the evidence base.
3. Get a grounded answer — from peer-reviewed sources.
4. Review citations — verify the supporting research.
5. Apply with judgment — clinical reasoning stays with you.

The evidence grounding is the key difference — answers aren’t guesses, they’re summaries of the research with sources you can check.

OpenEvidence vs. ChatGPT vs. UpToDate

	OpenEvidence	ChatGPT	UpToDate
Medical-specific	✅ Yes	No	✅ Yes
Grounded with citations	✅ Yes	❌ Hallucinates	✅ Yes
AI conversational	✅ Yes	Yes	❌ Search
Cost	Free (professionals)	Free tier	Subscription

OpenEvidence combines AI conversation with medical grounding — the best of both worlds. ChatGPT is general and unreliable for clinical use. UpToDate is authoritative but search-based, not conversational. OpenEvidence is the modern synthesis.

Who is OpenEvidence for?

• Physicians answering clinical questions.
• Nurses and advanced practitioners supporting decisions.
• Medical students learning evidence-based medicine.
• Researchers checking the literature.

It’s not for patients seeking diagnoses, general health questions, or non-medical use. For clinicians, it’s a decision-support tool.
