CoCounsel is an AI-powered legal assistant developed by Thomson Reuters (through its 2023 acquisition of Casetext) to help lawyers with research, contract analysis, document review, and legal drafting. Unlike enterprise-only tools like Harvey AI, CoCounsel is designed for law firms of all sizes -- from solo practitioners to large firms -- with no seat minimums and accessible per-user pricing. It integrates deeply with Thomson Reuters' Westlaw legal research platform and is trained on legal documents to handle complex tasks like deposition preparation, timeline creation, and multi-jurisdictional case law analysis.
Pricing ranges from $50-$500/user/month depending on usage and features. On Demand pricing costs $50-$75 per task for occasional use. Basic Research costs $220/month, CoCounsel Core costs $225/month, and All Access costs $500/month with unlimited usage and reference attorney support. Westlaw Precision with CoCounsel integrated costs $428/month for solo practitioners on 1-year contracts. Unlike Harvey AI's $30K-$300K+ annual minimums, CoCounsel welcomes solo practitioners and small firms at accessible monthly rates.
A critical consideration: CoCounsel Core at $225/month provides the best value for most small to mid-size firms, offering comprehensive AI document work, contract analysis, and research without Westlaw's premium database cost. Firms already using Westlaw should evaluate the Westlaw Precision bundle ($428/month) for seamless integration. On Demand pricing seems affordable at $50-$75 per task, but analyzing 10 documents monthly costs $500-$750 -- more than the unlimited Core subscription.
In this 2026 pricing guide, we break down CoCounsel's five plans, calculate real-world costs for solo practitioners and small firms, expose hidden fees like Westlaw integration premiums and contract term requirements, and compare CoCounsel to alternatives like Harvey AI, Clio, and general-purpose AI tools to help you determine if CoCounsel is the right legal AI platform for your practice.

CoCounsel by Thomson Reuters Pricing FAQ
01 How much does CoCounsel cost?
CoCounsel costs between $50-$500/user/month depending on the plan. On Demand pricing is $50-$75 per task for occasional use. Basic Research costs $220/month, CoCounsel Core costs $225/month, and All Access costs $500/month. Westlaw Precision with CoCounsel integrated costs $428/month for solo practitioners with 1-year contracts. Unlike Harvey AI, CoCounsel has no seat minimums -- solo practitioners and small firms can subscribe to any plan. Most small firms choose CoCounsel Core ($225/month) for comprehensive AI document work and research.
02 Is CoCounsel free?
No, CoCounsel does not offer a free plan or permanent free trial. Thomson Reuters offers limited free demonstrations and trial periods for prospective customers, but ongoing use requires a paid subscription starting at $220/month for Basic Research. For free legal AI tools, consider general-purpose options like ChatGPT (limited free tier), Claude (limited free tier), or free legal research resources like Google Scholar, though these lack the legal-specific training and Thomson Reuters integration that CoCounsel provides.
03 What is CoCounsel?
CoCounsel is an AI-powered legal assistant developed by Thomson Reuters (originally created by Casetext before Thomson Reuters acquired Casetext in 2023). It uses large language models trained on legal documents to assist with research, contract analysis, document review, deposition preparation, timeline creation, and legal drafting. CoCounsel integrates with Thomson Reuters' Westlaw legal research platform and is designed for law firms of all sizes -- from solo practitioners to large firms. It competes with Harvey AI but targets a broader market with accessible pricing and no enterprise minimums.
04 CoCounsel vs Harvey AI: which is better?
CoCounsel is more affordable and accessible than Harvey AI. CoCounsel costs $220-$500/user/month with no seat minimums, while Harvey AI costs $100-$500/user/month but requires 25-50+ seat minimums ($30K-$300K+ annual contracts). CoCounsel offers out-of-the-box legal research and integrates with Westlaw, making it ideal for solo practitioners and small to mid-size firms. Harvey AI excels at custom AI models trained on firm documents and complex multi-jurisdictional workflows for large enterprise firms. Choose CoCounsel for immediate access, lower cost, and Westlaw integration. Choose Harvey for deep customization and enterprise features if you meet the seat minimums.
05 CoCounsel vs Clio: which should I choose?
CoCounsel and Clio serve different purposes but can complement each other. CoCounsel is a specialized legal AI research and drafting tool ($220-$500/user/month), while Clio is a practice management platform ($39-$139/user/month) with time tracking, billing, case management, and document management. Clio's Complete plan ($139/user/month) includes AI-powered drafting features, while CoCounsel provides deeper legal research and document analysis. Choose CoCounsel if your primary need is AI research and drafting. Choose Clio if you need comprehensive practice management. Many firms use both: Clio for operations and CoCounsel for research.
06 What features are included in each CoCounsel plan?
On Demand ($50-$75/task) includes pay-per-use document review and basic research. Basic Research ($220/month) includes AI legal research, case law analysis, and document summarization. CoCounsel Core ($225/month) adds advanced document work, contract analysis, deposition preparation, and timeline creation. All Access ($500/month) adds federal and state case law, reference attorney support, CARA AI search, and unlimited usage. Westlaw Precision with CoCounsel ($428/month) bundles full Westlaw database access with all CoCounsel features and KeyCite.
07 Does CoCounsel have a seat minimum?
No, CoCounsel has no seat minimums. Solo practitioners can subscribe to any CoCounsel plan starting at $220/month for Basic Research or $225/month for CoCounsel Core. This is a major advantage over Harvey AI, which requires 25-50+ lawyer minimums. CoCounsel's accessible pricing and lack of minimums make it the leading legal AI choice for solo practitioners and small firms. Volume discounts are available for larger firms, but they are not required to access the platform.
08 Can I integrate CoCounsel with Westlaw?
Yes, CoCounsel integrates directly with Westlaw through the Westlaw Precision with CoCounsel plan ($428/month for solo practitioners with 1-year contracts). This integration allows lawyers to use CoCounsel's AI capabilities while researching within Westlaw's comprehensive legal database, including KeyCite, all state and federal case law, and other Westlaw tools. The integration is seamless and designed for lawyers who already rely on Westlaw for research. Standalone CoCounsel plans (Basic, Core, All Access) do not include Westlaw access.
09 What are the alternatives to CoCounsel?
Alternatives to CoCounsel include Harvey AI ($100-$500/user/month, enterprise-only with 25-50+ seat minimums), Clio with AI drafting ($39-$139/user/month for practice management with AI features), Westlaw Precision standalone (varies by jurisdiction and contract), general-purpose AI tools like ChatGPT Plus or Claude Pro ($20/month individual), and legal research databases like Fastcase (free through many bar associations) or Google Scholar (free). For solo practitioners and small firms, CoCounsel offers the best balance of legal-specific AI, Thomson Reuters integration, and accessible pricing without enterprise minimums.
