// Why EuKosmos

Built by a researcher,
for researchers

Most reference managers treat your data as a service. EuKosmos treats it as yours. Everything saves to a plain folder — JSON files you can read, copy, back up with git, and access without EuKosmos if you ever need to.

DOI-first enrichment cascade

Paste a DOI and EuKosmos queries all 6 databases in sequence, filling every field it can find — authors with ORCIDs, abstract, BibTeX, citations, OA links.

SQLite + JSON hybrid

Data lives in a reliable SQLite database for performance, with human-readable JSON exports always kept in sync alongside it.

Browser extension

Add papers and save PDFs from any publisher page in one click — using your institutional access, no CAPTCHA, no manual renaming.

// DOI Enrichment Cascade

Every major database.
One paste.

Paste a DOI (or arXiv ID, ADS bibcode, InspireHEP key) and EuKosmos queries all databases in order, filling the richest metadata possible. No duplicates — each database contributes only what the others don't have.

// Researchers say

Built for the way
researchers actually work.

Finally a reference manager that doesn't lock my data behind a subscription. The DOI cascade is extraordinary — paste a DOI and everything fills in from ADS to Semantic Scholar automatically.

The browser extension changed how I collect papers. One click from the publisher page and the PDF is saved with the right filename, right in my EuKosmos folder. No more Downloads folder chaos.

HEP Researcher Particle physics experiment, CERN

I manage papers, proposals, collaborators, and my CV all in one place. And because it's a local folder, I can sync it with my institutional Dropbox without worrying about data privacy.
