Overview

Zotero is a free, open-source reference manager. It helps you collect citations from the web, store PDFs, annotate sources, and generate bibliographies in thousands of citation styles.

It runs as a desktop app (macOS, Windows, Linux) with browser connectors for Chrome, Firefox, and Safari. There’s also a web library for access anywhere.

If you write academic papers, reports, or long-form research, managing sources manually is slow and error-prone. Zotero saves time by capturing metadata automatically, keeping your sources organized, and formatting citations correctly.

It’s especially valuable for students, academics, journalists, and policy researchers who want a powerful tool without paying for expensive licenses.

You save sources from your browser with one click. Zotero detects books, journal articles, web pages, and PDFs, then pulls in citation data automatically. Files sync across devices, and you can insert citations directly into Word, Google Docs, or LibreOffice.
