The Verdict
Connected Papers is built for researchers and students, with a focus on paper-graphs and prior-works. Mendeley targets researchers and phd students and leads with reference-management and pdf-annotation.
Mendeley uses custom enterprise pricing, while Connected Papers starts at $3/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for researchers, academics — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Connected Papers has a slight overall edge — but if free matters most to you, Mendeley may still be the right call.
