The Verdict
Westlaw is built for law firms and corporate legal, with a focus on case-law and statutes. Zotero targets researchers and students and leads with reference-management and pdf-annotation.
Westlaw uses custom enterprise pricing, while Zotero starts at $20/mo — a tangible advantage for teams with a fixed budget.
Zotero 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.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
