Evidence

Ask a clinical question. The answer is synthesized only from validated, published sources, and cited one by one. This is research summarization for clinicians, not medical advice.

Searches run against PubMed and Europe PMC, and against the guideline documents published by bodies including the US Preventive Services Task Force, the American Heart Association and American College of Cardiology, and the National Institute for Health and Care Excellence. Nothing is drawn from blogs, forums, or the model's own memory.

Do not include patient identifiable information in questions. Answers can take up to a minute while the literature is retrieved and summarized.

How it works

Your question is turned into searches that favor systematic reviews and randomized controlled trials, plus a separate pass for guideline documents from the bodies named above. Where a guideline covers your question, the answer leads with what it recommends and names the body and the year, then uses the primary literature for nuance or disagreement. The retrieved sources, and nothing else, are handed to a summarizer that must cite one of them for every claim. Every answer links its sources so you can read the papers yourself. If the literature retrieved does not answer the question, the answer says so plainly.
