The Verdict
Connected Papers is built for researchers and students, with a focus on paper-graphs and prior-works. Hugging Face targets ml engineers and researchers and leads with model-hub and datasets.
On pricing, Connected Papers is the clear winner for budget-conscious users — starting at $3/mo compared to $9/mo for Hugging Face. That $6/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Hugging Face edges out on user ratings (4.7 vs 4.3). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Both tools are a solid fit for researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Hugging Face has a slight overall edge — but if visual graph exploration matters most to you, Connected Papers may still be the right call.
