Worth knowing
Connected Papers
- Free accounts are limited to 5 graphs per month; unlimited graphs need a paid plan.
- Prices are set by visitor location. The US prices here come from an Internet Archive copy of the pricing page's own price data, captured on October 1, 2026.
- The Academic plan is restricted to academic, non-profit and personal use; for-profit work needs the Business plan.
- Subscriptions run for a full year or quarter and renew automatically, and the terms allow refunds only for overlapping coverage.
ResearchRabbit
- 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.
Key features
Connected Papers
- Similarity graphs
- Each graph is built by analyzing about 50,000 papers and keeping the few dozen most strongly connected to the origin paper, arranged so that similar papers sit close together.
- Prior and derivative works
- The Prior Works view lists important ancestor papers in the field, and the Derivative Works view lists literature reviews and recent papers that followed the origin paper.
- Multi-origin graphs
- A paper found in a graph can be added as another origin, so that one graph is built around several starting papers instead of one.
- Saved papers and graph history
- Papers can be saved to a list and earlier graphs reopened from a history. Graphs, saved papers and history can each be downloaded as a .bib file.
- Search by title or identifier
- Start a graph from keywords, a paper title, a DOI, or a paper URL from arXiv, Semantic Scholar or PubMed.
- Group plans
- On group plans, administrators assign premium access to members from a pool of purchased seats on one invoice, at the same price per seat. Seats added mid-cycle are charged pro rata.
ResearchRabbit
- 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.
