Connected Papers
Visual graphs of similar academic papers for literature search
What is Connected Papers?
Connected Papers is a web tool that builds a visual graph of the papers most closely related to one you choose. Papers are placed by similarity, measured through co-citation and bibliographic coupling, so related work clusters together even when the papers do not cite each other. It draws on the Semantic Scholar corpus, and separate views list the prior and derivative works for the starting paper.
Connected Papers has a free plan. Paid plans start at $6 per month, billed annually ($72). See every plan

- Prices are set by visitor location. The US prices here come from an Internet Archive copy of the pricing page's own price data, captured on October 1, 2026.

- Subscriptions run for a full year or quarter and renew automatically, and the terms allow refunds only for overlapping coverage.
Key features
- Similarity graphs
- Each graph is built by analyzing about 50,000 papers and keeping the few dozen most strongly connected to the origin paper, arranged so that similar papers sit close together.
- Prior and derivative works
- The Prior Works view lists important ancestor papers in the field, and the Derivative Works view lists literature reviews and recent papers that followed the origin paper.
- Multi-origin graphs
- A paper found in a graph can be added as another origin, so that one graph is built around several starting papers instead of one.
- Saved papers and graph history
- Papers can be saved to a list and earlier graphs reopened from a history. Graphs, saved papers and history can each be downloaded as a .bib file.
- Search by title or identifier
- Start a graph from keywords, a paper title, a DOI, or a paper URL from arXiv, Semantic Scholar or PubMed.
- Group plans
- On group plans, administrators assign premium access to members from a pool of purchased seats on one invoice, at the same price per seat. Seats added mid-cycle are charged pro rata.
