Explore the academic literature as a visual graph of related papers
Each graph places the seed paper among its most closely related works, clustered by how often papers are cited together or share references.
Separate perspectives show what a paper builds on and what later work builds on it, which is ideal for tracing a research lineage.
Start from a paper title, DOI, URL or proceedings link, so you can enter the graph from whatever you already have at hand.
A ranked list view lets you browse related publications by relevance when you need specifics rather than an overview.

Find similar research papers in one click, powered by AI search
Press the extension on any research paper page and get a ranked list of conceptually related papers without retyping queries.
Results come from the Exa AI search engine, which ranks by meaning and context rather than exact keyword matches.
Because retrieval runs through the Exa API, Dewey is not locked to a single repository and can act on publisher pages, preprint sites, and personal pages.
The extension ships as a very small package and shows no advertising, keeping page load and interface overhead minimal.
