What is ResearchRabbit?
ResearchRabbit is a literature review and paper discovery tool, now run by Litmap Limited, the team behind Litmaps. You start with one or more seed papers you trust, and it analyzes their references, citations and co-authors to recommend related work. It searches more than 310 million academic papers and says it is trusted by over one million researchers and thousands of institutions.
What sets ResearchRabbit apart from keyword search is its visual, iterative "rabbit hole" flow. A configurable citation graph shows how papers connect, and the recommendations learn from each search and from what you add. You can organize finds into collections, share them with collaborators and bring in your existing reference library, and the free tier covers everything most students need.
