Challenges & Solutions
Built for how clinicians actually work
The problem
A literature review means searching, opening twenty papers, reading, and keeping track of what said what
The solution
Wysor searches, screens, and summarises, and keeps a citation on every statement, so you check sources instead of collecting them.
The problem
Abstracts leave out the methods and numbers you need
The solution
Full-text search inside ~10M open-access papers, including preprints, finds the passage that answers your question.
The problem
A retracted paper slips into your reference list
The solution
Retracted papers are flagged in results, and citation counts show how often each study has been cited.
The problem
You cannot paste unpublished or patient-related data into a consumer AI tool
The solution
Wysor is EU-hosted with zero data retention and does not train on your content.
Ask a research question, get cited studies
Type your question in English, German, French, or another language, for example "what do randomised trials show for SGLT2 inhibitors in heart failure with preserved ejection fraction?". Wysor searches the literature and trial data and answers with the studies it used, so every statement can be traced to its source.
An AI literature review over 40M+ citations
Wysor searches 40M+ citations and filters by study type, date, journal, and language. Retracted papers are flagged, and citation counts show how often a study has been cited. For methods and numbers that abstracts leave out, it searches inside ~10M open-access full-text papers, including preprints.
Trials and drug data in the same search
Clinical trial registry data covers ~500K trials with phase, status, eligibility criteria, and outcomes, so ongoing studies show up next to published ones. Drug questions draw on 256K drug labels, 20M adverse-event reports, and EU-approved medicines with German SmPC text.
Your documents and the literature, together
Upload your own PDFs, a protocol, or a set of papers, and ask questions across them and the published literature at once. For a structured review, see our systematic review and clinical trials search pages.
Private, because research data is sensitive
Wysor is EU-hosted with zero data retention and does not train on your queries or uploads. It helps you find and understand evidence; it does not diagnose or replace a physician.
FAQ
Frequently Asked Questions
AI can do the search, screening, and first summary of a literature review.
