ResearchRabbit is a visual discovery tool for academic literature reviews that helps researchers find and organize papers through citation networks and algorithmic recommendations. It searches across 280+ million articles from sources like Semantic Scholar and PubMed, with a free tier and a paid ResearchRabbit+ plan starting at $10/month (annual billing).
ResearchRabbit is a literature discovery platform designed for academic researchers conducting systematic reviews. Rather than presenting endless search results, it visualizes how papers connect through citations, identifies key authors, and uses algorithms that learn from user behavior to suggest relevant research. The tool searches across 280+ million articles from databases including Semantic Scholar and PubMed, allowing researchers to create collections, collaborate by sharing, and track research trends. Users can upload their existing libraries and organize findings into collections, with the free tier supporting up to 50 seed articles and the paid tier expanding that to 300 for large-scale reviews.
Yes, ResearchRabbit offers a free tier that includes unlimited searches across 280+ million articles, unlimited library and collections, collaboration features, and support for up to 50 seed articles. This free tier is described as 'Free Forever' and includes everything needed for a focused literature review.
ResearchRabbit integrates with Semantic Scholar for broad academic coverage and PubMed for biomedical and life science literature. Users can also upload their existing libraries to the platform. Specific details about other integrations or reference manager compatibility were not found in our research.
ResearchRabbit is often compared to Connected Papers and Litmaps for literature visualization. According to reviews, its visualization features are less developed than these specialized alternatives, though it offers strong search capabilities across a large database. After being acquired by Litmaps, users report the tool has become more similar to its competitor. Semantic Scholar is noted as having excellent search but less developed visualization compared to these tools.
