Mendeley AI
FreemiumFree Elsevier reference manager with Scopus integration, paper recommendations, and 2GB of cloud storage
What is Mendeley AI?
Mendeley is a free reference manager owned by Elsevier, the academic publisher behind ScienceDirect and Scopus. It's been a staple of research workflows for more than a decade and today offers a free 2GB cloud-synced library (more generous than Zotero's 300MB free tier), cross-platform desktop and web apps, and the Mendeley Cite plugin for Microsoft Word. Since the Elsevier acquisition in 2013, Mendeley has been tightly integrated with Elsevier's other products, which is a double-edged sword. On one hand, you get seamless paper recommendations powered by Scopus's enormous citation graph, automatic access to institutional subscriptions, and high-quality metadata extraction. On the other, concerns about Elsevier's ownership of research data have pushed privacy-conscious academics toward Zotero and open-source alternatives. Mendeley's AI story changed sharply during 2026. Alongside Scopus-driven paper recommendations and smart metadata lookup, it now ships Reading Assistant, a native PDF chat assistant, plus Ask My Library, which answers questions across the PDFs in your library and returns traceable citations, and Compare Experiments. That closes most of the gap with ReadCube Papers and Humata, though the free allowance is just 5 Reading Assistant questions and unlimited AI now sits behind a paid Premium plan that Elsevier sells directly at $4.99, $9.99, or $14.99 per month. Mendeley remains a solid fit for researchers in medicine, life sciences, and engineering, fields where Scopus coverage dominates, and for anyone whose institution already has an Elsevier subscription that upgrades the Mendeley experience. The tradeoff is no longer about missing AI; it is about cost and data ownership, since the free AI allowance is tiny and Elsevier holds the keys.

FAQ
Is Mendeley free?
Yes. Mendeley Reference Manager is free to use with 2GB of personal cloud storage, which is more generous than Zotero's 300MB free tier, plus 5 groups of up to 25 collaborators and 5 Reading Assistant AI questions. You can store, organize, and cite thousands of references without paying a cent. Elsevier now also sells Mendeley Premium directly to individuals: Plus at $4.99/month, Pro at $9.99/month, and Max at $14.99/month. Separately, many universities provide upgraded access through Mendeley Institutional Edition.
Who owns Mendeley?
Mendeley is owned by Elsevier, the academic publishing giant behind ScienceDirect and Scopus. Elsevier acquired Mendeley in 2013 and has integrated it tightly with its other research products. This ownership is controversial in academia: on one hand it means seamless access to Scopus-indexed papers and institutional subscriptions, on the other it raises data ownership concerns that push some researchers toward Zotero.
Does Mendeley have AI features?
Yes, and this changed substantially during 2026. Alongside personalized paper recommendations and smart metadata extraction, Mendeley now ships Reading Assistant, a native PDF chat assistant comparable to ReadCube Papers or Humata, plus Ask My Library, which searches and answers across the PDFs in your library and returns citations you can trace back to the source, and Compare Experiments. Free accounts get 5 Reading Assistant questions; unlimited use requires a paid Premium plan. Elsevier also markets LeapSpace, a separate AI research workspace that bundles the Mendeley Premium features.
Mendeley vs Zotero, which is better?
Zotero wins on openness, privacy, and plugin ecosystem. Mendeley wins on free storage (2GB vs 300MB), Scopus integration, and a slightly more polished interface. Researchers concerned about data ownership almost always pick Zotero. Those who already use Scopus heavily, work at institutions with Elsevier subscriptions, or just want more free storage out of the box may prefer Mendeley. Both integrate with Word and Google Docs.
Can I use Mendeley with Word and Google Docs?
Yes. Mendeley Cite is the official plugin for Microsoft Word, and a separate integration exists for Google Docs via browser extensions or third-party tools. Mendeley supports thousands of citation styles including APA, MLA, Chicago, Harvard, and most major journal styles. The Word integration is solid and has been the traditional strength of Mendeley since before the Elsevier acquisition.
How does Mendeley's paper recommendation work?
Mendeley uses your library, reading history, and Scopus's massive citation graph to surface personalized paper recommendations. These appear on the Mendeley dashboard and in search results. Because Scopus indexes peer-reviewed literature deeply, recommendations often surface relevant papers you'd miss on Google Scholar. The feature works best in medicine, life sciences, and engineering fields where Scopus coverage is strongest.
Is Mendeley good for collaborative research?
Mendeley supports private groups for sharing papers, annotations, and notes with co-authors. Free accounts can create groups with up to 25 members. It's a decent option for lab collaboration, though Zotero and Papers both offer more flexible group features. For institutional-scale collaboration, Mendeley Institutional Edition (MIE) provides enhanced admin and storage but is typically purchased by libraries rather than individuals.
Does Mendeley work offline?
Yes. The Mendeley desktop app (also known as Mendeley Reference Manager) stores your library locally and lets you read, annotate, and cite papers without an internet connection. Your library syncs with the cloud once you reconnect. This makes it usable on planes, in the field, or anywhere with unreliable WiFi, a practical advantage for researchers who travel frequently or work in remote locations.
