Zotero review
A flexible, free citation manager with strong capture, annotation, and writing-tool support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Zotero is a reference-management application for students, researchers, educators, and research teams. It captures bibliographic information from webpages, organizes sources with collections, tags, and saved searches, and generates citations and bibliographies. Its free, open-source core also supports PDF reading and annotation, notes, attachments, group libraries, and synchronization across devices. The combination suits researchers who want one workspace for collecting sources, managing a library, and citing material while writing.
The published plans show a free tier with 300 MB of storage, while paid Zotero Storage subscriptions add capacity for attached files such as PDFs and images. The 2 GB plan costs $20 per year, 6 GB costs $60 per year, and Unlimited costs $120 per year. The desktop reference manager and core data syncing are free, so paid storage is mainly relevant to researchers with larger file collections or teams that need to synchronize more attachments. This structure keeps the main citation workflow accessible while making storage the primary paid consideration.
Zotero fits a wide range of research setups. It offers web, Windows, macOS, Linux, iOS, and Android access, plus a Chrome extension and browser capture through Firefox, Chrome, and Safari. Writing integrations cover Microsoft Word, LibreOffice, and Google Docs, while WebDAV provides another file-storage connection. Import support includes formats such as BibTeX, BibLaTeX, RIS, EndNote XML, MODS, MARC, MEDLINE/nbib, PubMed XML, and Web of Science Tagged. Researchers who need broad platform coverage, collaborative group libraries, and detailed source organization should consider Zotero. Those who want larger synchronized file storage without a subscription may prefer a different tool.
