What is ResearchRabbit?
ResearchRabbit is an academic literature discovery tool that turns seed papers into interactive citation networks, author maps, and personalized recommendations across over 310 million articles.
ResearchRabbit reimagines literature discovery by shifting away from rigid keyword querying toward interactive visual exploration. Researchers begin by selecting relevant seed papers, which the system uses to analyze citations, bibliographies, and co-authors across a corpus of more than 310 million academic papers. As users navigate related papers and build collections, the platform's recommendation algorithms adapt dynamically to reading patterns and topic interests. The visual citation graph traces connections between papers and authors, allowing researchers to spot foundational studies, identify emerging themes, and uncover relevant literature gaps without sifting through static lists. The service provides collaborative collection sharing and reference library syncing. A free tier covers essential literature review workflows with up to 50 seed articles, while an upgraded premium tier (ResearchRabbit+) expands capacity to 300 seed articles, introduces integrity signal alerts, and adds multi-project organization.
Unlike standard bibliographic databases that return flat lists of keyword hits, ResearchRabbit builds an interactive citation graph from seed papers that iteratively refines recommendations as you curate collections.
