Search-intent editorial guide
Connected Papers creates a visual similarity graph around an origin paper and highlights related, prior, and derivative work. The graph represents similarity based on citation relationships rather than a simple citation tree, so it is useful for orientation but should not be read as proof that every nearby paper directly cites the origin.
Choose Connected Papers when you need a quick, focused map from one known paper. The free plan is practical for occasional use but is limited to five graphs per month. ResearchRabbit is the stronger choice for persistent collections and repeated expansion across a longer literature-review project.
Editorial review date: August 10, 2026
Connected Papers visualizes the academic paper ecosystem by creating interactive graphs that show how papers cite each other and share research themes. Users can explore forward and backward citations, find seminal works in a field, and identify papers that have influenced or been influenced by a given publication. The platform works with major academic databases and makes literature discovery more intuitive than traditional search.
Interactive citation graph visualization that maps paper relationships and influence
Forward and backward citation exploration to trace ideas across time
Integration with major academic databases including PubMed, arXiv, and SSRN
PhD students beginning a new research project exploring which foundational papers and recent advances define their topic
Researchers identifying gaps in literature by visualizing what has been studied and what connections remain unexplored
Literature review authors mapping the evolution of ideas across related papers to build a coherent narrative
Yes. The official free plan includes all core features and five graphs each month. Academic and Business plans remove the graph limit; commercial users should choose the Business context described on the official pricing page.
It positions papers by similarity calculated from co-citation and bibliographic-coupling patterns. It is not a chronological citation tree and should be combined with abstract and full-text review.
The official pricing page separates Academic and Business use. For for-profit work, review the Business plan and current terms before relying on the service.
