Top Free Reference Managers
Zotero

Mendeley
Mendeley, owned by Elsevier, is particularly popular in STEM fields. It excels in PDF handling and includes built-in academic search. Mendeley offers up to 2GB of free cloud storage and integrates with Word. It supports annotation, collaboration, and syncing, though some features are limited in the free version. Its proprietary nature and dependency on Elsevier’s ecosystem can be restrictive for some users.
EndNote Web
EndNote Web is the free online version of Clarivate’s EndNote. It offers basic reference management with integration to Web of Science and Word. While not as feature-rich as Zotero or Mendeley, it’s a solid option for users who prioritize cloud access and institutional integration.
