Mendeley Reference Manager vs Zotero

Mendeley Reference Manager is a web and desktop application for organizing references and supporting research workflows. Users can import PDFs or folders into a library, read and annotate documents, and collect thoughts in Mendeley Notebook. Mendeley Cite inserts citations and builds bibliographies in Microsoft Word using a chosen style. Shared groups let colleagues, course-mates, or co-authors contribute references and annotate PDFs together. Web Importer saves papers, web pages, and other documents from search engines and academic databases; it is available for Chrome, Firefox, Edge, and Safari. Watched Folders can import PDFs placed in a selected desktop folder. Offline mode syncs library changes after reconnecting. Free accounts include 2GB of storage and five Reading Assistant questions. Paid plans start at $4.99 per month, with higher tiers listing additional storage and Reading Assistant features. Mendeley is available on web, Windows, Linux, macOS, and as a browser extension. The Windows download page lists Windows 10 and above as supported.

Zotero is an open-source tool for collecting, organizing, annotating, citing and sharing research. Its browser Connector can identify research items during browsing and save them to a library. Collections, keyword tags and saved searches help organize material, while a PDF reader and note editor support working with documents. Zotero supports over 9,000 citation styles and integrates with Microsoft Word, LibreOffice and Google Docs. The desktop app stores research locally by default; syncing is optional. Zotero Storage can sync PDFs, images, web snapshots and other files across devices, with access through an online library. Libraries can be shared with any number of people at no cost, and groups support shared collections. The free plan includes 300 MB of storage; paid storage starts at $20/year for 2 GB. Zotero says synced data is encrypted in transit and newly created accounts' data is encrypted at rest with AES-256. The data server is in the United States. The data server software can be run locally, though Zotero says self-hosting is technically challenging and unsupported. Most support takes place in public forums.
