Casetext vs CoCounsel: What Happened After the $650M Acquisition

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.

Pricing
Casetext: discontinued March 31, 2025. CoCounsel Core: $225/user/month. Westlaw Precision with CoCounsel bundle: $428/user/month. Annual commitments typical. Legacy Casetext 'locked in for life' promotional pricing was not honored after the acquisition migration.
User Reviews
Casetext
Casetext (legacy) reviews on G2 frequently praised the affordable price point ($150-225/month) and ease of use for solo practitioners. Reviews after the Thomson Reuters acquisition note pricing changes and feature roadmap uncertainty.
CoCounsel
CoCounsel has 282+ reviews on G2 as of 2026. Common praise: Parallel Search speed, citation accuracy on document review, learning curve under one day. Common complaints: no Westlaw editorial synopses included in Core tier, requires bundling with Westlaw Precision for full value, deposition output format limitations.
When to pick Casetext
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.
When to pick CoCounsel
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.
Frequently Asked Questions

- What did Thomson Reuters pay for Casetext?
- $650 million, announced in June 2023 and closed in August 2023. Casetext was the first major legal AI acquisition by a top-tier legal information provider.
- Did Casetext customers keep their pricing?
- No. Customers with legacy Casetext promotional pricing — including 'locked in for life' offers — were migrated to current Thomson Reuters rates. Many reported substantial price increases at renewal.
- Is CoCounsel the same product as Casetext?

New features have been added through Westlaw integration. The branding, pricing structure, and product roadmap are now controlled by Thomson Reuters.
- What is CoCounsel best at?
- Legal research with Westlaw integration, document review with citation extraction, deposition preparation, and contract analysis.

Our take
There is no real choice to make here. CoCounsel is what Casetext became. The more useful comparison for current buyers is CoCounsel vs Lexis+ AI, or CoCounsel vs Harvey AI — see our scored profiles for both.
