Systematic review software
Systematic review software that actually searches beyond MEDLINE.
Cochrane handbook §4.3 says a defensible search reaches beyond PubMed and Embase — into regional, non-English, and grey-literature sources. Most systematic review software stops at the screening step. Symmathy starts at the search step.
One query, federated across PubMed, Europe PMC, Cochrane CENTRAL, ClinicalTrials.gov, J-STAGE (Japan), LILACS (Latin America), HAL (France), DOAJ, OpenAlex, and CrossRef. Non-English titles and abstracts are translated inline. Every record links to its source — Symmathy never rewrites, scores, or recommends.
What's included
Federated search
One query, 10+ databases run in parallel, including the regional sources most reviewers search by hand.
Inline translation
Titles and abstracts translated from Japanese, Portuguese, Spanish, French, Thai, and more — original always one click away.
Reproducible audit trail
Every search logs sources queried, query terms, and timestamps — the data a PRISMA flow diagram needs.
Source-first, no grading
No quality scores, no "best paper" badges. Risk-of-bias and GRADE stay with the reviewer.
How it fits your workflow
Symmathy covers the search and discovery phase. Export records to Covidence, Rayyan, DistillerSR, or EndNote for screening, dual-reviewer extraction, and risk-of-bias assessment. The goal is to make the search phase reproducible and complete — without ten browser tabs.
Frequently asked questions
Does Symmathy replace Covidence or Rayyan?
No. Symmathy is search-first. Covidence and Rayyan are screening-first. They complement each other — most teams use a federated search tool to find records and a screening tool to deduplicate and review them.
Which databases are covered?
PubMed, Europe PMC, Cochrane CENTRAL, ClinicalTrials.gov, J-STAGE, LILACS, HAL, DOAJ, OpenAlex, CrossRef, and a growing list of regional indexes. See the full list on the Sources page.
Can I export results for screening?
Yes — RIS, BibTeX, and CSV are supported, with original-source URLs preserved.
