Connected Papers in 60 Seconds

You give Connected Papers a DOI or paper title. It generates a force-directed graph where:

  • Node size = number of citations (prominent papers appear larger)
  • Node colour = age of publication
  • Edge thickness = similarity between papers

Papers that appear close together share many references and citations — they belong to the same research cluster.

When to Use It

Starting a literature review: paste your best-known reference, immediately see the landscape of the field, identify which papers are most central.

Finding seminal work: the largest, oldest nodes in the graph are almost always the foundational papers everyone in the field cites.

Checking coverage: if you think you’ve been thorough, generate a Connected Papers graph from one of your citations. Nodes you haven’t read that appear large are gaps.

Free vs. Paid

The free tier gives 5 graphs per month — usually enough for a targeted search. Paid access ($3/month) removes the limit. For a literature review phase that might span weeks, the paid tier is worth it.

Combine Connected Papers with Research Rabbit: use Connected Papers for topology (big picture), Research Rabbit for depth (iterative discovery).
