The Verdict
Casetext (CoCounsel) is built for solo practitioners and small law firms, with a focus on ai-research and brief-analysis. Westlaw targets law firms and corporate legal and leads with case-law and statutes.
Westlaw uses custom enterprise pricing, while Casetext (CoCounsel) starts at $110/mo — a tangible advantage for teams with a fixed budget.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
Both tools are a solid fit for legal researchers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
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.
