Map the literature around the papers you love—free
Start from one paper and see how research connects through a visual map of related works, authors and citations.
The more you explore and select, the better it learns your interests, surfacing smarter and more relevant recommendations.
Explore how your existing review connects and discover papers you may have missed, avoiding endless flat article lists.
Bring your reference library and ResearchRabbit together so your collection and discovery work in one place.

Map the relationships hiding inside biomedical literature
SOMA parses published studies and pulls out the factors, exposures and outcomes they discuss, so you can examine the evidence base without reading every paper in full first.
Extracted relationships are organized into a connected graph, letting you start from one condition or factor and follow the links outward to related variables.
Each relationship in the graph is tied back to the studies that reported it, so you can open the source paper and judge the evidence yourself.
Search across study relationships to see which factors have been investigated together and where findings cluster or conflict.
