# ResearchRabbit

> Literature discovery tool that maps how papers connect

ResearchRabbit is a web tool for finding research papers by starting from ones you already know. You pick seed articles and it surfaces similar, earlier and later work from a database of more than 310 million articles, shown as lists and interactive citation maps. Papers are saved into shareable collections, and a paid tier called ResearchRabbit+ adds larger searches, advanced filters and multiple projects.

## Key features

- **Seed-based paper search:** Start from one or more papers you already know and find similar, earlier and later work. Free accounts search from up to 50 seed articles and RR+ from up to 300.
- **Citation maps:** Interactive maps show how papers and authors connect through citations and references, which helps in tracing how an idea developed.
- **Collections:** Save papers to collections and subcollections, mark them with notes, stickers and colors, and share a collection with collaborators or through a public link.
- **Zotero and BibTeX:** The Zotero Importer brings in papers saved in Zotero, and articles can be imported and exported as BibTeX files. Both are part of the free tier.
- **Advanced search filters:** RR+ adds filters for keywords, publication date, journal quality, open access and retractions, plus separate projects for different papers.
- **Signals risk badges:** In RR+, each article carries a Signals badge marking no major risks, caution, alert or unable to check. The full report needs a free Signals account.

## Good for

- Citation chasing from a few key papers at the start of a literature review
- Students and researchers who want a free tool with no cap on searches
- People who prefer to see a field as a map of connected papers and authors

## Worth knowing

- Free accounts can use up to 50 seed articles per search; RR+ raises that to 300.
- Advanced search filters, multiple projects and Signals badges are only in RR+.
- Recommendations rely on citation and authorship links; ResearchRabbit says its core algorithms do not use large language models.
- Articles without open-access metadata are not indexed, so some papers and citations can be missing.
