Sources
Evidence sources searched
40M+ study citations
Filter by study type, including systematic reviews, meta-analyses, and RCTs, and by date, journal, and language, with citation counts.
Open-access full text
Around 10 million open-access papers, including preprints, searched in full for the methods and numbers behind a result.
Retraction detection
Retracted papers are flagged, so an answer does not rest on a study that has been withdrawn.
Clinical trial registry data
Around 500,000 registered studies, to see which trials on a question are still running.
What you can search
What you can look up
Cited answer
A direct answer to the clinical question, with each statement linked to the study it comes from.
Study type shown
Whether a statement rests on a systematic review, a meta-analysis, an RCT, or another study type, made visible.
Publication date
Filter by date and see when each source was published, so you can tell if newer evidence exists.
Ongoing trials
Registered studies still recruiting on the same question, for evidence that is not published yet.

Challenges & Solutions
Built for how clinicians actually work
The problem
Acquiring and appraising evidence takes longer than a clinic slot allows
The solution
Ask in plain language. Wysor searches 40M+ study citations and around 10 million open-access full texts and answers with every source cited and linked.
The problem
You need to know what kind of study a statement rests on
The solution
Filter by study type, such as systematic reviews, meta-analyses, or RCTs, and see the study type next to each source.
The problem
A retracted or outdated paper can quietly shape an answer
The solution
Retracted papers are flagged, and date filters show whether newer evidence exists.
The five steps of evidence-based medicine
Evidence-based medicine is usually taught in five steps: ask a focused clinical question, acquire the evidence, appraise it, apply it to the patient, and assess the result. Wysor works on the second and third steps. It finds the studies and makes their type, date, and source visible. Applying the evidence and assessing the outcome remain clinical judgement.
Acquire: one question, 40M+ citations
Ask in plain language. Wysor searches 40M+ study citations, filterable by study type, date, journal, and language, and around 10 million open-access full-text papers including preprints. Every statement in the answer is cited and linked, so you can open the study behind it.
Appraise: study type, date, and retractions
Appraisal starts with knowing what you are reading. Wysor shows whether a source is a systematic review, a meta-analysis, an RCT, or another study type, when it was published, and how often it has been cited. Retracted papers are flagged. For questions where evidence is still coming, registry data for around 500,000 trials shows which studies are still running.
