Mendeley is a reference management and academic research tool that helps users collect, organize, annotate, and cite scholarly literature. It combines a cloud-synced PDF library, built-in PDF reader with annotations, automatic citation generation, and Word/LibreOffice citation plugins to streamline literature workflows. Mendeley’s key differentiator is its integrated cloud storage plus group sharing features tailored for academic teams, serving students, researchers, and faculty. Pricing is accessible with a free tier that includes basic library storage and citations, and paid plans unlock more cloud space and team collaboration features in the Research & Learning category.

About Mendeley

Mendeley is a desktop and web-based reference manager first developed in 2008 and later acquired by Elsevier in 2013; it positions itself as a productivity hub for academic research and literature management. Its core value proposition is to let researchers centralize PDFs, metadata, annotations, and citations in one synced library that works across Windows, macOS, Linux, iOS, and Android. Mendeley targets scholarly workflows where tracking sources, generating bibliographies in multiple citation styles, and sharing reading lists across collaborators are essential, and it integrates with word processors and institutional access systems to reduce manual referencing work.

Mendeley’s primary features include a cloud-synced PDF library that automatically extracts metadata from uploaded files and can organize documents into folders and subfolders. The built-in PDF viewer supports highlighting and sticky-note annotations that are saved to the cloud and visible across devices. Its citation plugin (Mendeley Cite for Microsoft Word and a plugin for LibreOffice) inserts citations and generates bibliographies in thousands of styles, with the ability to change citation styles on the fly. Mendeley also provides group libraries for sharing selected folders with collaborators, with limits based on plan, and a researcher profile that can be used to discover related papers and track readership statistics. The desktop app supports bulk import of RIS, BibTeX, and EndNote XML files and can watch folders to auto-import PDFs.

Mendeley’s pricing includes a Free plan with basic features and limited cloud storage, plus paid plans to increase storage and group size. The Free plan provides a personal library with 2 GB of cloud storage at no cost. Paid upgrades are offered as Mendeley Plans (such as Plus and Pro) that increase storage—historically increments like 5 GB and 10 GB or institutional/Team subscriptions—while Team/Institutional options are quoted as custom enterprise pricing that unlock larger shared storage and admin controls. Elsevier periodically updates exact plan names and pricing; individuals can upgrade for more storage and larger private group sizes, while universities negotiate site licenses for campus-wide deployment.

Mendeley is used by graduate students for managing literature reviews, by principal investigators coordinating lab reading lists, and by academic librarians for curating institutional collections. For example, a PhD student uses Mendeley to organize 600+ PDFs, annotate readings, and export a BibTeX file for LaTeX manuscripts, while an assistant professor manages a 12-member research group's shared folder for reproducible reading lists and manuscript references. Compared with competitors like Zotero, Mendeley leans on Elsevier integrations and built-in PDF annotation syncing, though users often weigh privacy and open-source preferences when choosing between them.

What makes Mendeley different

  • Integrated PDF annotation syncing across desktop and mobile that preserves highlights and notes in the cloud.
  • Direct Elsevier integrations for institutional access and discovery tied to Scopus/ScienceDirect metadata.
