Casetext and CoCounsel are the same product. Thomson Reuters acquired Casetext for $650M in August 2023 and discontinued the standalone Casetext platform on March 31, 2025. CoCounsel is now the active brand, integrated with Westlaw Precision. If you are comparing these two names, you are comparing a 2023 product to its 2026 successor. We document what changed and what to expect at the current price point.

Start with workflow fit, then verify price and evidence before procurement.
Casetext as a name is historical. Lawyers searching for 'Casetext' in 2026 are typically researching legacy pricing, archived feature sets, or alternatives outside the Thomson Reuters ecosystem. If you held a legacy Casetext subscription, your account has been migrated to Thomson Reuters rates — usually a significant increase.
CoCounsel makes sense for firms that already use Westlaw or are willing to bundle. The $428/month Westlaw Precision with CoCounsel bundle is a better deal than buying Westlaw + CoCounsel Core separately. Solo practitioners on tighter budgets often find the Core tier at $225/month difficult to justify without the Westlaw bundle.
AI legal research pioneer (CARA AI); standalone retired 2025, its technology now powers Thomson Reuters CoCounsel.
Thomson Reuters' GPT-backed legal research and drafting with Westlaw integration (relaunched as CoCounsel Legal, 2025).
