Overview

Mendeley builds AI directly into reference management: AI Search & Insights interprets the actual logic and intent behind a search query rather than just matching keywords, pulling context-rich insights from across your documents, and pattern recognition uncovers relationships and missing links across your entire reference collection that would be tedious or impossible to spot manually across hundreds of papers.

Surfacing missing links across a reference library is the feature that actually changes how literature review works – researchers often miss relevant connections between papers simply because no single person can hold hundreds of documents’ relationships in mind at once, and AI pattern recognition doing that connecting work systematically, rather than only when a researcher happens to notice a link themselves, catches things a purely manual review would miss.

Mendeley remains a full reference manager beyond the AI layer: 2GB of free cloud storage, PDF management with annotation, citation generation, cross-device sync, collections and tagging, and browser/Word integrations. Getting started on Mendeley Web appears to carry no apparent cost barrier; full pricing details are in a dedicated pricing section not shown on the homepage.
