Mendeley Reference Manager

Overview

Import PDFs or entire folders with a click or by dragging and dropping, or collect papers, web pages and other documents through Web Importer. The browser extension supports Chrome, Firefox, Edge and Safari, and the library also accepts BibTeX, EndNote XML and RIS files. This range gives researchers several practical routes to bring existing and newly found material together.

Watched Folders automatically add PDFs placed in a selected desktop folder, a useful option for people who already save papers in a consistent place. Mendeley also has an offline mode: library changes sync when you reconnect, which helps when working without internet access.

Key features

The PDF reader supports comments, highlights and annotations, and Mendeley Notebook gives readers a place to collect thoughts. That makes the app more useful than a citation list for people who want reading notes alongside their papers. Groups provide shared libraries where colleagues, course-mates or co-authors can add references and annotate PDFs in real time. This is a clear advantage for collaborative reading, though the core use case remains research rather than general document management.

Mendeley Cite inserts citations and builds bibliographies in Microsoft Word using a chosen citation style. Researchers who write in Word get a direct route from their library to a formatted bibliography; readers using another word processor should not choose Mendeley for this feature.

Free accounts include five Reading Assistant questions. Plus, Pro and Max make Reading Assistant questions unlimited; Pro and Max also include Compare Experiments and Ask My Library. The free allowance is modest, so frequent use of the assistant points toward a paid plan.

Uploaded data is secured using the AES-256 standard applied by major banks. That is a stated security measure, but it does not by itself describe every aspect of data handling.

Pricing

The free plan is a reasonable starting point for a library that fits within 2GB and needs only occasional Reading Assistant questions. Plus raises storage to 5GB and removes that question limit, but does not include Compare Experiments or Ask My Library. Pro adds both tools and doubles Plus storage; Max is the option for users who need those same features without a stated storage ceiling. The paid prices are monthly; the free plan costs 0.00 USD per free.

Platforms

Mendeley is available on the web, Windows, macOS, Linux and as a browser extension. Windows support covers Windows 10 and above, while the Linux download is a generic 64-bit version. There are no mobile apps, so it is a weaker fit for people who need a dedicated phone or tablet app. The download page points users to the Mendeley Support Center and release notes for help and updates.

Who it's for

Mendeley is a strong fit for students, academics and co-authors who organize PDFs, annotate papers and write in Microsoft Word. Its shared libraries suit groups that need to contribute references and discuss PDFs together. It is less compelling for mobile-first researchers or for someone whose library exceeds the free 2GB cap but who does not want a paid plan.

Pros and cons

• Pros: PDF importing, annotation, Notebook notes and Word citations connect core research tasks in one application.
• Pros: Real-time group libraries support shared reference collection and PDF annotation.
• Pros: Offline mode syncs library changes after reconnecting.
• Cons: Free storage is capped at 2GB, which can constrain a large PDF collection.
• Cons: The free plan includes only five Reading Assistant questions.
• Cons: No mobile apps are offered, and Word is the stated writing integration.

Alternatives

Citation Management Software and Reference Management Software are useful starting points for comparing tools across these categories.

Choose Zotero instead if mobile access or a broader platform mix matters: it lists Android and iOS apps as well as Linux, macOS, web, Windows, an extension, API and self-hosted options. Its free plan has 300 MB storage, while a 2 GB plan costs 20.00 USD per year.

Sciwand may suit readers looking for core reading, organizing and writing tools free forever, with AI free for 7 days; its paid Lifetime plan is 29.99 USD per once. Consider Databyss if a free, non-commercial open-source application is the priority. JabRef is another free and open-source option with Linux, macOS and Windows support and a browser extension.

Lean Library Workspace is worth considering for a project-focused workflow: its Free basic plan allows up to 3 projects and up to 3 invitations per shared project, with no article or smart citation suggestions. Petal offers a free plan with 1 GB storage, 1 seat, 3 guests, 400 AI credits and 2 collections, but citation export is not included.

EndNote may be preferable for someone seeking a one-time upgrade purchase: its Upgrade License is 94.00 USD per once for EndNote 21 or earlier users and EndNote 2025. Bookends is another alternative.

Verdict

Choose Mendeley if you want to keep PDF reading, collaborative reference libraries and Microsoft Word citations together, especially when offline access matters. Its main reason to look elsewhere is the combination of a 2GB free cap and no mobile apps; researchers who need more space or phone-based access should compare other tools before settling in.
