The Verdict
Mendeley is built for researchers and phd students, with a focus on reference-management and pdf-annotation. Westlaw targets law firms and corporate legal and leads with case-law and statutes.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Mendeley has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Westlaw requires a paid subscription from day one.
Westlaw edges out on user ratings (4.4 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Bottom line: Westlaw has a slight overall edge — but if free matters most to you, Mendeley may still be the right call.
