Medical literature search and evidence synthesis
Search, understand and synthesise medical research
One query reaches PubMed, Europe PMC, OpenAlex, Crossref, bioRxiv and medRxiv. Verisium keeps what you find organised around the question you are asking, and every claim stays linked to the study it came from.

The network
The world's largest medical research network
Records, authors, journals and the citations between them, connected into one searchable network.
Scholarly and biomedical research records
Across six connected open research sources.

Journals

The problem
The record is complete. Finding your way through it is not.
Hundreds of millions of papers, abstracts and citation links are already open and searchable. What is still hard is working through them without losing the thread: which studies answer your question, where they agree, and where the evidence runs out.
Verisium is built for that middle ground. It searches the sources you already trust, groups what matters into persistent workspaces, and helps you read across studies while keeping the reasoning visible. Our methodology sets out what it does, and what it does not claim to do.
How a question moves through Verisium
- 01
Search
One query across six open databases, deduplicated and enriched.
- 02
Discover
Read abstracts, metadata and publication status before you commit.
- 03
Connect
Group what you find into a workspace built around your question.
- 04
Understand
Compare populations, methods and outcomes side by side.
- 05
Synthesise
Record agreements, contradictions and gaps, each linked to its source.
The toolkit
Six parts that work on the same question
Each one stands alone. Together they carry a review from first search to a traceable conclusion.
See how it works- 01
Multi-source search
PubMed, Europe PMC, OpenAlex, Crossref, bioRxiv and medRxiv from a single field, deduplicated and enriched with metadata and abstracts.
- 02
Research workspaces
Evidence organised around a research question, so a review stays in one place instead of a folder of PDFs.
- 03
Research Copilot
Ask questions of the studies you have collected. Answers are grounded in the retrieved evidence, not the model's memory.
- 04
Research Radar
Follow topics and surface new papers, emerging findings, and results that contradict what you already hold.
- 05
Evidence tables
Structured comparison across populations, interventions, comparators and outcomes.
- 06
Evidence synthesis
Overall findings, points of agreement, disagreements and research gaps, with claim-level citations.
Who it is for

Frequently asked questions
- What is AI-assisted evidence synthesis?
- AI-assisted evidence synthesis uses language models to help researchers identify, organise and summarise findings across multiple studies. Verisium surfaces agreements, disagreements and research gaps while keeping every claim linked to its source, so any statement can be traced back to the underlying evidence.
- How does Verisium search medical literature?
- Verisium searches PubMed, Europe PMC, OpenAlex, Crossref, bioRxiv and medRxiv from a single field. Results are deduplicated and enriched with metadata, abstracts and publication-status checks, so you can judge what is relevant and trustworthy.
- Is Verisium suitable for systematic reviews?
- Verisium supports the early stages of a systematic review: searching, screening and organising evidence. It does not replace formal systematic-review methodology, risk-of-bias assessment or the PRISMA reporting process, so use it alongside established review standards.
- Can I use Verisium for my PhD literature review?
- Yes. Verisium helps PhD students search efficiently, organise evidence around research questions, and synthesise findings with traceable citations. It complements, but does not replace, the critical appraisal and methodology expected in academic research.
