Verdict

For most students: Zotero (free) covers nearly all needs. It’s open-source, feature-rich, and genuinely costs nothing.

For Word users wanting paraphrasing: GenText ($9.99/month) is excellent value, offering more than just citations.

For Google Docs writers: Paperpile is optimized for that ecosystem.

For large research teams: Mendeley or institutional EndNote/RefWorks.

For final quality assurance: Combine any citation tool with Scribbr’s proofreading service.

Most important: Check your institutional library first. Many universities provide free access to premium tools that cost $99+/year individually. This single step can save significant money and provide institutional support.

No single tool is “the best”—the best tool is the one that fits your writing platform, budget, and workflow. Start with free options (Zotero, CiteThisForMe), then add premium tools if needed (GenText, Paperpile).
