Litmaps vs ResearchRabbit

Litmaps is a web-based research tool that uses citation networks and advanced search to help researchers find papers and conduct literature reviews. Its search catalogue contains more than 270 million papers. A Litmap visualizes connections among articles through citations and references; users can annotate papers and change how the map is arranged. Topic monitoring sends automatic emails when new articles appear, and maps can be shared as images, public links, or with selected email addresses. The free plan costs nothing and includes basic search, up to 20 inputs and 100 articles, one Litmap, and a monthly summary, but no collaboration. Pro (Education) costs $10 a month, billed $120 / year - save 20%; it adds advanced search, unlimited inputs, articles, and Litmaps, plus daily or configurable alerts, and requires an academic email address. Litmaps Pro syncs Zotero collections with Litmaps Tags in both directions. Articles can also be imported from BibTeX, RIS, or PubMed files and exported in BibTeX, RIS, or CSV formats. Open Access PDFs are available to all users; other PDF access requires institutional access through LibKey.

ResearchRabbit is a web service for discovering research related to papers users select. It analyzes those papers and recommends connected work, with interactive maps showing links among papers, authors and concepts. Its recommendations adapt to reading patterns and research interests. The Free plan costs nothing and provides unlimited searches across more than 310 million articles, an unlimited library and collections, sharing, core search settings and up to 50 seed articles. ResearchRabbit+ raises the seed limit to 300 and adds advanced search controls, multiple projects, Signals alerts and faster support responses. Its annual plan costs $10 a year (billed per month, Annual plan); the monthly plan costs $12.50 a month (billed per month, Monthly plan). Users can import selected articles from Zotero collections and export articles as BibTeX. ResearchRabbit is aimed at researchers and students, and does not provide screening workflows, full-text management or systematic review tools.
