The Fragmentation Problem

Every researcher runs 7+ disconnected tools. None of them talk to each other. You're the bridge — and it's costing you hours every week.

YOUR CURRENT SETUP
ZOTEROMENDELEYNOTION OBSIDIANOVERLEAFGDOCS SHEETSTODOISTTRELLO SLACKDROPBOXEMAIL
💀 Data scattered across 12 apps in 7 formats on 3 clouds.
Where was that paper you read last month?
🔌
Tool Fragmentation
Papers in Zotero, notes in Notion, code in Gists, jobs in a spreadsheet, proposals in email. Nothing is connected. You spend more time moving data between tools than actually researching.
☁️
Cloud Dependency Trap
Notion is down at 2am during a deadline. No WiFi at the telescope. Your subscription gets cancelled. Your research held hostage by servers you don't control.
🔒
Data Lock-in
Mendeley was nearly shut down by Elsevier in 2023. Papers 3 was abandoned for Papers 4, breaking years of libraries. Your data should outlive any company.

One Tool. Every Research Task.

Designed for the full lifecycle of academic research — not just references. 15 integrated sections, all data cross-linked, all deadlines unified.

Why EuKosmos?

We compared EuKosmos against the three tools most researchers use. Where EuKosmos doesn't yet win, we say so — and explain why it's a deliberate design choice.

† EuKosmos opens PDFs in your default viewer (Preview, Acrobat, Skim) — your annotations are saved to the file and persist. We think your existing PDF tool is better than anything we'd build.

Built for How Researchers Actually Work.

Finally a reference manager that doesn't lock my data behind a subscription. The DOI cascade is extraordinary — paste an ADS bibcode and everything fills in automatically from ADS to Semantic Scholar.
AstrophysicistRadio galaxy research, European observatory
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 ResearcherParticle physics experiment, CERN
I manage papers, proposals, referee lists, and my CV all in one place. Because it's a local folder I can sync with institutional Dropbox without worrying about data privacy.
