Where Casetext wins
Casetext is no longer operational, so it offers no current advantages. When it was active, it had a significantly lower starting price point compared to CoCounsel. The service directed users to Westlaw for legal research and CoCounsel for legal AI upon shutdown.
Where CoCounsel wins
Active service: CoCounsel is currently operational while Casetext shut down in April 2025. Users seeking AI legal assistance must now use alternative platforms.
Broader professional scope: CoCounsel serves legal, tax, audit, and accounting professionals, not just legal practitioners. This makes it suitable for firms with multi-disciplinary needs.
Thomson Reuters integration: CoCounsel is built on Thomson Reuters' authoritative content and integrates with their broader ecosystem of professional tools, including Westlaw.
Pricing comparison
Both tools operate on paid-only models with no free plans or trials. Casetext's pricing was positioned at a lower entry point when operational. CoCounsel requires a paid subscription with a higher starting threshold. Neither tool offers freemium access, making them enterprise-focused solutions requiring upfront financial commitment. Exact current pricing should be verified on each tool's official page.
Who should choose Casetext?
Casetext is no longer available. Former Casetext users are directed to Westlaw for legal research or CoCounsel for AI-powered legal assistance. Anyone seeking the functionality Casetext provided should evaluate CoCounsel or other active legal AI platforms.
Who should choose CoCounsel?
Multi-disciplinary firms: Organizations with legal, tax, audit, and accounting teams can use a single AI platform across departments.
Thomson Reuters ecosystem users: Firms already using Westlaw or other Thomson Reuters products will benefit from integrated workflows and consistent authoritative content.
Enterprise legal teams: Organizations requiring AI assistance for legal research, document review, contract analysis, and drafting with enterprise-grade security and domain expertise.
Verdict
This is not a competitive comparison since Casetext ceased operations in April 2025. CoCounsel is Thomson Reuters' current AI legal assistant offering, representing the evolution of legal AI tools following the Casetext acquisition. Anyone previously considering Casetext must now evaluate CoCounsel or alternative legal AI platforms. CoCounsel's broader professional scope and Thomson Reuters backing make it suitable for enterprise users, though the higher price point requires careful ROI evaluation.
