Zotero vs. EndNote: Reference Manager Guide
Zotero (free, open-source) vs. EndNote (paid, Clarivate): compare cost, citation styles, Word/Google Docs support, sharing, and platforms for researchers.
Side-by-side comparison
| Dimension | Zotero | EndNote |
|---|---|---|
| Cost model | Free, open-source; optional paid storage ($20/yr for 2 GB up to $120/yr unlimited) | Commercial; single-user license commonly $250–$350 (varies by reseller/edition), often free to users via an institutional site license |
| Developer | Corporation for Digital Scholarship (non-profit) | Clarivate (commercial; also publishes Web of Science) |
| Citation style format | Citation Style Language (CSL) — open, XML-based, thousands of free/editable styles | Proprietary "output style" format; thousands built in, editable in EndNote’s own style editor, not natively CSL-compatible |
| Word processor plugins | Microsoft Word, Google Docs, LibreOffice/OpenOffice | Cite While You Write for Microsoft Word (and LibreOffice/OpenOffice on some platforms); no official Google Docs support |
| Reference capture | Zotero Connector browser extension (Chrome, Firefox, Safari, Edge) — one-click save from catalogs, publisher sites, Google Scholar | Web-based capture via EndNote online; less central to the workflow than Zotero’s Connector |
| Team/library sharing | Group Libraries: private, public closed-membership, public open-membership | Share Library: up to 1,000 collaborators, Read & Write or Read-Only access, requires EndNote Sync/Online account |
| Desktop platforms | Windows, macOS, Linux | Windows, macOS (no native Linux client) |
| Mobile support | Official iOS app; no official Android app | EndNote online (web) for cross-device access; no dedicated phone app in the same sense as Zotero iOS |
| Free storage for attachments | 300 MB free; library metadata itself syncs free/unlimited | Cloud sync via EndNote online, bundled with a license; allowances vary by edition |
| Typical fit | Individual researchers, students, and teams without a guaranteed institutional license, or anyone drafting in Google Docs | Labs/departments with an existing EndNote site license, Word-only workflows, or large actively co-edited shared libraries |
Common questions
FAQ
Is Zotero as good as EndNote?+
For most individual and small-team workflows, yes — Zotero covers the same core functions (collecting references, formatting citations, attaching PDFs) at no cost. EndNote’s advantages are concentrated in large-team library sharing (up to 1,000 collaborators) and in institutions where EndNote is already the established, supported standard.
Can I convert an EndNote library to Zotero, or the other way around?+
Yes, using standard exchange formats like RIS or EndNote XML — the reference data itself transfers. What doesn’t transfer automatically is anything tool-specific, such as custom output/CSL styles or citations already inserted in a manuscript via one tool’s Word plugin, which need to be re-linked after import.
Does my university give me EndNote for free?+
Many do, through an institutional site license, which is why EndNote’s list price is often irrelevant in practice for affiliated researchers and students. Check your library’s software page or research-computing site to confirm whether your institution holds one.
Which one works with Google Docs?+
Zotero has a native, official Google Docs citation plugin. EndNote does not offer official Google Docs support — its Cite While You Write plugin targets Microsoft Word (and LibreOffice/OpenOffice on some platforms).
