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.
Highlight dense research text and get plain-language explanations instantly
Select any confusing sentence or term and receive an immediate plain-language explanation that accounts for the rest of the paper.
Shift the reading level from beginner-friendly to expert-detail so the explanation matches your background.
Ask questions and get answers grounded in the document's actual content, with references back to the relevant sections.
Produce a smart outline, key-point extraction, and concept relationship views without reading the entire paper first.
