Zotero saves a source, its citation, and your notes in one click, free on Mac, Windows, Linux, and phones
The tool academics have used for years is the best filing cabinet an ordinary reader never installed.
Zotero describes itself as a free tool to collect, organize, annotate, cite, and share research, and it runs on Mac, Windows, Linux, iOS, and Android as open-source software from a nonprofit. Its browser connector notices when you are looking at something worth keeping, whether that is a library record, a page on arXiv or JSTOR, or a newspaper article, and files the item with its citation details rather than a bare link. Writing at XDA on September 1, Yash Patel says it is the best productivity tool he owns and that he uses it well outside academic work, saving articles into collections by subject, annotating PDFs, and keeping snapshots and notes beside the sources. The honest limit is storage: the software and your local library cost nothing, but syncing attached files across devices is capped at 300 MB free, with 2 GB at $20 a year, 6 GB at $60, and unlimited at $120.
