ResearchRabbit review

ResearchRabbit is a discovery tool rather than an answer engine. You start from one or more seed articles and it shows related papers, citations and co-authors, so you can follow a topic outward and spot the authors and gaps in a field. The free plan is generous: unlimited searches across more than 310 million articles, an unlimited library and collections, shared collections for collaboration and up to 50 seed articles. ResearchRabbit+ costs $10 a month on the annual plan or $12.5 monthly at the default rate that covers the US, UK and Canada, and it adds up to 300 seed articles, advanced search controls, multiple projects, Signals alerts and faster support. RR+ is discounted in more than 100 countries based on purchasing power. Institution plans add LibKey integration and usage statistics. The limit is clear: it does not summarize papers or write a review, so most people use it next to an AI assistant that does.
