Zotero
Zotero is a free reference manager and research tool for collecting, organizing, citing, and syncing sources across your devices.
What is Zotero?
Zotero is a free, open-source research management application published by the Corporation for Digital Scholarship. It is designed to help students, academics, writers, and other researchers collect bibliographic references, PDFs, notes, and web sources in one searchable library. On macOS, users commonly encounter it as a desktop app paired with browser connectors that can capture citation details from library catalogs, journal sites, and web pages. Zotero also integrates with word processors such as Microsoft Word and LibreOffice to insert citations and build bibliographies while writing. Libraries can be organized with collections, tags, saved searches, and synced online for use across multiple devices. It is commonly installed intentionally for academic or professional work rather than appearing as bundled background software.

Safety overview
Status: Safe
Zotero is a well-known legitimate research tool from the Corporation for Digital Scholarship. It can store local research libraries, notes, and attached documents, and it may sync that data to a Zotero account if you enable syncing. The main privacy consideration is the academic material, PDFs, annotations, and account data you choose to store or synchronize, not hidden system risk.
Recommendation: Keep if you use Zotero for research, citation management, PDF organization, or word processor citation plugins. If you no longer use it, removal is usually optional after confirming you no longer need your local library, attachments, browser connector workflow, or synced research data.
