Is CoCounsel (by Casetext) Worth It?

✅ Why Choose CoCounsel (by Casetext)

  • • Citations are grounded in Westlaw's authoritative case law, statutes, and secondary sources, reducing the hallucination risk that plagues general-purpose LLMs in legal work
  • • Purpose-built skills (document review, deposition prep, contract analysis, legal research memos) follow structured workflows attorneys actually run, rather than forcing prompt engineering
  • • Handles very large document sets — hundreds of thousands of pages — with consistent question application across the entire corpus
  • • Deep integration with the Thomson Reuters stack (Westlaw, Practical Law, Document Intelligence, HighQ) and Microsoft 365 (Word, Outlook) puts AI inside existing attorney workflows
  • • Enterprise-grade security posture: SOC 2 Type II, no model training on customer data, role-based access, matter-level segregation, and audit trails suited for regulated practice
  • • Backed by Thomson Reuters' legal content licensing and editorial infrastructure, giving customers a single accountable vendor rather than stitched-together point tools

⚠️ Consider This

  • • Pricing is quote-only and positioned at firm/department scale — not accessible or transparent for solos and small firms evaluating cost
  • • Maximum value is realized only by existing Westlaw subscribers; standalone use loses much of the grounded-citation advantage
  • • Outputs still require attorney review and verification — the tool does not eliminate the professional responsibility to check every cite and conclusion
  • • Skill-based workflow can feel rigid compared to open-ended assistants when a task does not map cleanly to a predefined skill
  • • Coverage is strongest for U.S. federal and state law; non-U.S. jurisdictions and highly specialized practice areas may be thinner

Pricing FAQ

Who is CoCounsel built for?

Licensed attorneys, paralegals, in-house legal teams, and — through CoCounsel Core — tax, audit, and risk professionals. It is designed for regulated professional work where citation accuracy, confidentiality, and auditability are required, rather than for casual or consumer use.

Does CoCounsel hallucinate citations like ChatGPT?

CoCounsel is grounded in Westlaw's authoritative legal databases and the documents users upload, with retrieval-augmented generation that links every answer back to source material. This substantially reduces fabricated citations compared to general LLMs, but Thomson Reuters still instructs attorneys to verify every output before relying on it in practice.

Is my client data used to train the underlying models?

No. Thomson Reuters' enterprise terms for CoCounsel state that customer data and uploaded documents are not used to train foundation models, and the platform operates with SOC 2 Type II controls, role-based access, and matter-level data segregation.

How does CoCounsel compare to Harvey and Lexis+ AI?

Harvey is a custom AI platform aimed primarily at large law firms and competes on bespoke deployment and integrations. Lexis+ AI is the closest direct competitor, grounded in LexisNexis' Shepard's-cited content. CoCounsel's edge is its tight Westlaw and Practical Law grounding plus a mature library of pre-built attorney skills and workflow integrations across Word, Outlook, and HighQ.

What does CoCounsel cost?

Thomson Reuters does not publish public list pricing. CoCounsel is sold via direct sales as part of (or alongside) a Westlaw subscription, with seat- or firm-level pricing negotiated based on user count, modules (Legal, Drafting, Core), and integration needs.
