The Verdict
Semantic Scholar is built for researchers and phd students, with a focus on semantic-search and tldr-summaries. 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.
Semantic Scholar 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.
