Connected Papers vs ResearchRabbit

Connected Papers is an academic research tool that provides visual overviews of academic fields by building graphs of similar papers based on an input paper. It helps researchers discover important papers, create bibliographies, and identify prior and derivative works.

ResearchRabbit is a literature review tool that helps researchers discover, organize, and understand scholarly papers through visual mapping of citation and topic connections, rather than plain keyword search lists. It draws on a database of over 310 million academic papers and shows how topics relate and evolve over time. The platform lets users organize papers and take notes to avoid losing track of ideas across a research project, and it integrates with reference managers like Zotero. It reports being trusted by over 1,000,000 researchers worldwide, including users at institutions such as Harvard, Stanford, MIT, Oxford, and Cambridge, and offers free sign-up.
