Is Dewey free to use?

Yes. The Chrome Web Store listing describes Dewey as completely free with no ads, and no paid plan is mentioned.

How does Dewey find similar papers?

It sends the paper you are viewing to the Exa AI search API, which returns documents that are semantically close to it rather than merely sharing keywords.

Does Dewey collect my data?

The developer states that the extension does not collect or use your data, does not sell it to third parties, and does not use it outside the extension's core functionality.

Which databases does it search?

Dewey is not tied to one repository. Because retrieval is handled by Exa's web-scale search, it can return results spanning publisher sites, preprint servers, and open web documents.

Can I use it outside Google Scholar?

Yes. Dewey operates on the page you are currently reading, so any paper page with a readable title and abstract can be used as a seed.

What is Dewey's monthly traffic and growth trend?

Dewey currently receives 0 monthly visits, with a month-over-month traffic change of +0 (0.0% growth rate). Its primary source market is Global (— share), including 0 direct visits/mo and 0 organic search visits/mo.

About Dewey

One-click similar-paper search

Press the extension on any research paper page and get a ranked list of conceptually related papers without retyping queries.

Semantic matching via Exa

Results come from the Exa AI search engine, which ranks by meaning and context rather than exact keyword matches.

Works on any paper page

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.

Zero-ads, lightweight build

The extension ships as a very small package and shows no advertising, keeping page load and interface overhead minimal.

Privacy-conscious defaults

The developer declares no data collection, no sale of data to third parties, and no unrelated use of browsing data.

Dewey solves a very specific and recurring problem in academic reading: you have found one good paper and now want the others that are conceptually close to it. Instead of reformulating queries by hand across a search engine or bibliographic database, Dewey reads the paper page you are currently on and returns a set of related papers, ranked by semantic similarity rather than keyword overlap.

The extension is deliberately small — the Chrome Web Store listing reports a package of roughly 14 KB — and the entire intelligence sits behind the Exa API, an AI-native search engine built for embeddings-style retrieval over web and document content. That architecture is why Dewey can act on any paper page you land on, not just ones hosted in a single database.

Dewey is free, has no advertisements, and the developer discloses that no user data is collected or sold. It is a good fit for graduate students, systematic-review authors, and anyone who routinely jumps between Google Scholar, publisher pages, and preprint servers and wants a faster way to expand a reading list.
