The all-in-one, local-first research workspace. Papers, notes, ideas, jobs, proposals, conferences, CV and your academic website — 18 integrated sections, auto-enriched from 7 scholarly databases, stored in open formats you own forever.
Papers in one tool, notes in another, deadlines in a third, job applications in a spreadsheet, proposals in email. None of them talk to each other — you are the integration layer.
You spend more time moving data between tools than doing research. Every context switch loses a thought.
Notion is down at 2am before a deadline. No WiFi at the telescope. Your work held hostage by servers you don't control.
Mendeley was nearly shut down by Elsevier. Papers 3 was abandoned, breaking years of libraries. Your data should outlive any company.
Built for the full lifecycle of academic research — 18 integrated sections, all cross-linked, all deadlines unified in one calendar.
Paste a DOI, arXiv ID, ADS bibcode, InspireHEP key, PMID or ISBN — full metadata cascades in from every major database. BibTeX import/export, auto citekeys, duplicate detection, read-status tracking, 10,000+ CSL citation styles.
Turn your EUKOSMOS data into a personal academic website — publications with live citation metrics, CV, grants and gallery, generated from what you already track. Publish to profile.eukosmos.com/you in one click, or download the HTML and host it anywhere.
→ how it worksTrack applications through the full funnel, manage referees with email templates — and search live academic job listings from the built-in portal.
→ how it worksSplit-pane Markdown editor with live KaTeX preview. Backlinks between notes and papers. Export to PDF or .docx.
→ how it worksEvery deadline from every section — proposals, todos, checklist steps, jobs, conferences — in one calendar with .ics import.
→ how it worksYour structured academic CV, assembled from data you already entered. Papers, talks, grants, positions — export as formatted .docx.
→ how it worksSQLite FTS5 with BM25 ranking across all 18 sections at once. Under 50 ms even with 10,000 papers.
→ how it worksExtend EUKOSMOS with native plugin sections. The Chrome extension clips papers from any publisher page straight into your library.
→ learn moreRead and annotate papers inside EUKOSMOS — highlights, sticky notes with threaded replies, text boxes and signatures. Annotations follow the ISO 32000 PDF standard, so they open in Acrobat, Preview and Firefox. Your original file is never modified.
→ how it worksOptional multi-device sync, end-to-end encrypted (Argon2id + XChaCha20-Poly1305). The server stores only ciphertext — your password and plaintext never leave your machine.
→ how it worksThe AI Lab plugin runs a local model on your own machine — summarise papers, extract job adverts, chat over your library. Fully offline; nothing is sent to any cloud.
→ learn moreNo account. No cloud. No dependencies. EUKOSMOS is a fully self-contained desktop app — download, install, and you're researching.
Grab the free desktop app for macOS (.dmg), Windows (installer) or Linux (AppImage). Everything is bundled — nothing else to install.
Double-click and EUKOSMOS opens in seconds. Optionally add your free NASA ADS token once in Settings to unlock astronomy-grade enrichment.
Drop in your .bib file or paste a DOI. Metadata fills itself in. Everything else — notes, jobs, deadlines — lives beside it.
# what you get ✓ one installer per OS — macOS · Windows · Linux ✓ no account needed · works fully offline ✓ your data: plain JSON + SQLite in a local folder you own
EUKOSMOS queries seven scholarly databases in sequence, taking the richest metadata each one offers.
Small, sharp, browser-based tools for researchers — each one free at its own subdomain.
EUKOSMOS runs entirely on your machine, and two tiers are free forever — including a free Student tier. Paid tiers add unlimited entries, more encrypted cloud sync, longer version history and multi-device access.
Prices in USD · loaded live from the EUKOSMOS control plane · subscriptions processed by Polar (merchant of record).
Checkout currently runs in sandbox test mode — no real charges until the production launch. Join early access to be notified.
Compared with the three tools researchers use most. Where we don't win yet, we say so.

† EUKOSMOS ships its own PDF reader and annotation editor: highlights, underlines, sticky notes with threaded replies, text boxes and signatures — written as ISO 32000-standard annotations that open in Acrobat, Preview and Firefox. Your original PDF is never modified. Prefer your own viewer (Preview, Acrobat, Skim)? External viewing still works exactly as before.
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, from ADS to Semantic Scholar.
The browser extension changed how I collect papers. One click from the publisher page and the PDF lands with the right filename, right in my EUKOSMOS folder.
I manage papers, proposals, referee lists and my CV in one place. Everything lives in a local folder, and the built-in encrypted sync keeps my office and laptop machines identical — without ever worrying about data privacy.
No account required to run it. No data leaves your machine unless you turn on sync.
macOS (Apple Silicon) · Windows x64 · Linux AppImage
Beta builds aren't code-signed yet (signing is coming). One manual step on first launch:
macOS — drag to Applications, then run xattr -cr /Applications/EUKOSMOS.app in Terminal and open normally (otherwise macOS says the app is "damaged").
Windows — SmartScreen warns: click More info → Run anyway.
Linux — chmod +x the AppImage, then run it.
One-click paper capture from any publisher page, straight into your library. Auto-detects the desktop app — zero setup. Privacy policy.
Get notified the moment a new build ships — plus first access to Pro tiers at launch. One email per release, nothing else.
Yes — there are two free tiers. Free gives you 200 entries and 200 MB of sync storage; the Student tier is also completely free with 500 entries and 500 MB — unlocked by verifying your academic email address. Paid tiers add unlimited entries, more encrypted cloud sync, longer version history and multi-device access. If a subscription ever lapses you degrade gracefully to Free — your data is never locked.
Subscriptions are processed by Polar as merchant of record — EUKOSMOS never sees your card details. You can manage or cancel any time from the customer portal. Checkout currently runs in sandbox test mode while we finalise payments; no real charges are made until the production launch.
Yes. EUKOSMOS includes a built-in PDF reader and annotation editor: highlights, underlines, strike-outs, sticky notes with threaded replies, text boxes and signatures. Annotations are written to the ISO 32000 PDF standard, so they open in Acrobat, Preview and Firefox — and your original file is never modified. It works fully offline. Prefer your own PDF app? Opening in an external viewer still works too.
In a local folder you choose: SQLite plus plain JSON and Markdown files. You can read every byte with standard tools and take it with you forever. For backup across devices, EUKOSMOS has its own built-in end-to-end-encrypted cloud sync — no third-party service needed.
Yes — export your library as a .bib file and bulk-import it. EUKOSMOS re-enriches every entry from the seven-database cascade, usually ending up with richer metadata than you started with.
Completely. Enrichment needs the internet to query the databases; everything else — reading, writing, searching, exporting — works with no connection at all.
Nothing but the app: download the desktop beta for Mac, Windows or Linux and double-click. The app is fully self-contained — no Python, no package managers, no runtime to install. (Beta builds are unsigned; code-signed installers with auto-update are coming.)
No — EUKOSMOS is commercial, closed-source software, built and maintained full-time by a researcher. What stays open is your data: everything lives in plain JSON, Markdown and SQLite files in a local folder you own, readable with standard tools forever — no lock-in, ever.
