Research Rabbit originally was known for its data visualizations which allow you to see connections between academic papers and authors. It has expanded its offerings to include a function that recommends papers based on your research interests and collaborative/sharing functions. You can upload papers and use DOIs and PMIDs to locate and add papers. Recommendations appear to be citation based but there is not an explanation of that function from the company.
Notes: From our own testing, the network and citations shown are not always related: we uploaded a digital scholarship article and it connected to other authors with the same last name, in completely different research fields, and included more general articles like about the philosophy of education.
Data sources: Research Rabbit was originally based on Microsoft Academic Graph which was retired December 31, 2021. It is unclear what data sources Research Rabbit is pulling from at this time.
