ResearchRabbit

ResearchRabbit is a citation network visualization and literature discovery platform for academic researchers, graduate students, and systematic review teams. Designed as a companion to academic databases rather than a replacement, it visualizes how papers cite each other, surfaces related work via content embedding, and tracks new publications by monitored authors or topics. Coverage spans 310+ million articles indexed via PubMed, Semantic Scholar, OpenAlex, and Crossref. The platform transitioned from a fully grant-funded free model to a freemium structure with the launch of the RR+ paid tier in 2025. In May 2025, Litmaps acquired ResearchRabbit, which now runs on Litmaps infrastructure while retaining its own exploratory-browsing interface. ResearchRabbit integrates natively with Zotero for reference import and export, and exports to standard reference formats including BibTeX and RIS. Academic database coverage includes PubMed, Semantic Scholar, OpenAlex, and Crossref for citation graph construction. No API is publicly documented for custom integrations and no MCP server has been published as of Q3 2026. Notable gaps include no native Mendeley integration (RIS export workaround required), no Overleaf or manuscript writing platform connector, no Scopus or Web of Science citation data, and no Notion or Obsidian connector for note-taking workflows. There is no dedicated desktop app. The platform is web-only. ResearchRabbit offers three publicly priced plans. Free ($0 forever): unlimited searches across 310+ million articles, unlimited library and collections, collaboration by sharing collections, up to 50 seed articles per collection, and core search settings. RR+ ($10/month on annual billing, monthly billing also available): everything in Free plus up to 300 seed articles for large-scale systematic reviews, advanced search controls, multiple projects for focused discovery per topic, and faster support responses. Special country discount codes are available for the RR+ plan. Institution: custom pricing for research libraries, includes everything in RR+ plus volume discounts, LibKey integration for full-text access, user management at scale, usage statistics, and dedicated support. ResearchRabbit is not suited for commercial research teams, market researchers, or non-academic knowledge workers. The citation network approach is built around academic publishing structures that do not map to business intelligence or industry research. For systematic review teams requiring formal screening, data extraction, and PRISMA reporting alongside discovery, Rayyan (from $4.99/mo) provides dedicated systematic review workflow features ResearchRabbit does not include. For AI-generated summaries and synthesis alongside discovery, Elicit (from $49/mo billed annually) combines paper search with AI extraction of research findings. For broader source coverage beyond peer-reviewed literature, Perplexity AI ($17/mo) and ChatGPT Deep Research ($20/mo) reach web and news sources ResearchRabbit does not index. As of Q3 2026, ResearchRabbit has launched the RR+ paid tier at $10/month annually, transitioning from a fully free model to freemium. Coverage has expanded to 310+ million articles. The Institution tier targets research library partnerships via LibKey integration. G2 shows 1 verified review at 4.5/5 with an unclaimed profile, reflecting primarily academic word-of-mouth adoption rather than commercial procurement. No MCP server has been announced. Competitor Elicit expanded AI synthesis capabilities through 2024-2025, widening the gap in AI-powered analysis depth relative to ResearchRabbit's discovery-first approach.
