Zotero vs. Mendeley: Academic Reference Management Comparison
Question: Should a student use 'Zotero' or 'Mendeley' for academic reference management, considering the integration with word processors and cloud storage limits?
Prepared by the ChoiceScore Research Desk · Editor-approved for the curated library · Reviewed July 20, 2026
Direct answer
The choice between Zotero and Mendeley depends on a student's preference for specific word processor integration versus a centralized, publisher-supported research ecosystem. Zotero provides robust compatibility with Word, LibreOffice, and Google Docs, while Mendeley offers an integrated platform for note-taking and sharing, with optional premium tiers for expanded storage and AI-assisted features.
