ResearchRabbit
by ResearchRabbit (Litmap Limited) · Application · also known as Research Rabbit, RR+
Literature-discovery app that grows collections of papers through citation and author networks and recommends related work, with a free-forever tier
Overview
ResearchRabbit is a web application for literature discovery. Users seed a collection with papers they already trust; the tool then maps how those papers connect to earlier and later work and to authors, and refines its recommendations as more items are added. Collections can be shared with collaborators and a reference library can be connected so existing references become seeds.
The product has a free tier described as free forever, with unlimited searches, libraries and collections and a cap on seed articles per collection. The paid ResearchRabbit+ subscription (monthly or annual) raises the seed cap, adds advanced search controls, multiple projects, alert "signals" and faster support; an institutional tier adds volume licensing, LibKey integration, user management and usage statistics. The site footer credits Litmap Limited.
As with other graph-based discovery tools, results depend on the coverage of the underlying bibliographic sources, and there is no public API for scripting.
Editorial note on uncertainty. The homepage footer credits Litmap Limited; the corporate relationship is not otherwise explained on the site. Zotero integration is inferred from the 'connect your reference library' feature and should be confirmed in-app.
