About Connected Papers
Visual literature mapping tool that generates citation-based interactive graphs to discover related academic papers, seminal works, and research trends, accelerating literature reviews for students, researchers, and R&D professionals.
What Connected Papers Does
Connected Papers builds interactive, force-directed graphs from a seed input (title, DOI, or keywords) so researchers can quickly see related academic papers, citation counts, publication year, and similarity relationships. The visual approach helps users identify clusters, seminal works, and research gaps faster than list-only searches.
The tool calculates similarity using co-citations, bibliographic coupling, and the Semantic Scholar corpus. Features include prior/derivative works views, filters by year or keywords, list exports, and Zotero integration for reference management.
Use cases include literature reviews, mapping new fields, tracking research trends, and preparing reading lists for grants, theses, or R&D projects.

Frequently Asked Questions
The free plan permits up to five graph generations per month and unlimited viewing of saved or public graphs; upgrading to Academic or Business removes the graph-generation limit.
Nodes are individual papers; node size represents citation count, color indicates publication year, and proximity reflects similarity calculated from co-citations and bibliographic coupling.
For commercial or for-profit work, the Business plan ($20/month billed annually at $240) is required; the Academic plan ($6/month billed $72/year) targets non-profits, academics, and personal use.
