Zotero

Free reference manager that keeps citations and PDFs together.

Visit Zotero Freemium Reviewed Sep 29, 2026

Zotero captures a citation from a browser tab in one click, stores the PDF beside it, and inserts formatted references into Word, LibreOffice, or Google Docs. Notes and highlights attach to the item, and group libraries let a lab or seminar share a reading list. It is the reference manager most universities recommend because it is free and open source, and it saves a snapshot of the page itself so a source does not vanish when the site changes.

Who it is for

Graduate students and research groups who need citations without a per-seat license.

Key features

  • One-click citation capture from the browser
  • Word and Google Docs citation plugins
  • PDF annotation with linked notes
  • Shared group libraries
  • BibTeX and RIS export

Where it falls short

Free sync covers only 300 MB, so anyone with a serious PDF collection ends up buying storage, and group library storage is charged to whoever created the group.

Pricing

Free and open source; optional storage plans start around $20 a year for 2 GB, and group storage counts against the owner.

Prices move; the tier structure is the part that stays true. Check current pricing on Zotero.
