For global health researchers
The diseases you study aren't published where PubMed is looking.
PubMed indexes roughly 5% of the world's medical journals — overwhelmingly North American and Western European. Most clinical research on dengue, Chagas, leishmaniasis, schistosomiasis, Japanese encephalitis, and other regionally-clustered diseases is published in Portuguese, Spanish, Japanese, French, or Thai, in databases PubMed doesn't index.
Symmathy searches the other 95%. One query runs in parallel across J-STAGE (Japan), LILACS (Latin America), HAL (France), ThaiJO (Thailand), DOAJ, OpenAlex, and more — alongside PubMed, Europe PMC, and Cochrane. Non-English results are translated inline. Every record links back to the original.
12+ sources, one search
Federated across regional databases the rest of the field still searches by hand — including the ones with the most evidence on tropical and neglected diseases.
Read in your language
Japanese, Portuguese, Spanish, French, Thai titles and abstracts translated inline. The original is always one click away.
Built for regional evidence
When 40% of the dengue literature is in Portuguese on LILACS, a PubMed-only search isn't a search — it's a sample. Symmathy treats regional databases as first-class.
We find. We don't grade.
No quality scores, no "best paper" badges, no clinical recommendations. Symmathy surfaces records and links to originals — interpretation is yours.
Why this matters
Treatment guidelines, systematic reviews, and policy decisions for diseases endemic to the Global South routinely cite only the English-language slice of evidence — because the rest is invisible to the tools we use. The result is reviews that exclude the populations most affected by the disease being reviewed. Symmathy is built to close that gap, not to interpret the evidence for you.
