Thomson Reuters does not publish a fixed price list for CoCounsel. Pricing is generated through an online self-serve configurator (for law firms with up to 10 attorneys) based on your firm size, jurisdiction, and contract term; firms with more than 10 attorneys are quoted by a sales representative. As a concrete anchor, the Westlaw Advantage with CoCounsel Essentials plan for a solo attorney with All States & Federal coverage is priced at $639.20/user/month on a 1-year term, or $639/user/month on a 3-year term (18% savings), per Thomson Reuters' public pricing configurator (checked June 9, 2026).

CoCounsel is Thomson Reuters' AI assistant for legal research, drafting, and document analysis, built on technology from Casetext (which Thomson Reuters acquired in 2023 and fully integrated, retiring the standalone Casetext product in March 2025). It is now sold under the CoCounsel Legal family of plans.

There are four CoCounsel plans: CoCounsel Essentials (the AI assistant on its own — agentic workflows, document review, drafting, summaries, and timelines); Westlaw Advantage with CoCounsel Essentials (adds Westlaw primary-law research, KeyCite, and litigation tools); Practical Law Dynamic Tool Set with CoCounsel Essentials (adds Practical Law's expert-created content); and CoCounsel Legal (complete access to everything). Each plan's price depends on the number of attorneys, the jurisdictions you need primary-law coverage for, and whether you choose a 1-, 2-, or 3-year term (2-year terms save 12%, 3-year terms save 18%).

Because pricing is configured per firm, there is no single “CoCounsel price.” For a solo attorney, the monthly per-user prices shown on Thomson Reuters' configurator ranged from roughly $104 to about $639 depending on the plan and coverage selected. To see exact pricing for your firm, use Thomson Reuters' online configurator or request a demo.

5 CoCounsel by Thomson Reuters Hidden Costs Beyond the List Price

Beyond the listed price, CoCounsel by Thomson Reuters has at least 5 documented hidden costs that can significantly increase total cost of ownership.

Watch for 5 hidden costs
  • Westlaw research is a separate cost driver: CoCounsel Essentials is the AI assistant alone. Getting Westlaw primary-law research with it requires the Westlaw Advantage with CoCounsel Essentials plan, which for a solo attorney runs $519.35–$639.20/user/month depending on term — materially more than the AI-only tier.
  • Jurisdiction scope inflates the price: the Westlaw Advantage and CoCounsel Legal plans price primary-law coverage by the circuits you select. 'All States & Federal' is the most expensive option; a single-circuit practice pays less, while multi-jurisdiction practices pay more.
  • Term length lock-in: the advertised per-month rates assume multi-year commitments (12% off for 2 years, 18% off for 3 years). A 1-year term costs more per month, and the discounted solo rate ($519.35/mo) is only available if you commit for three years.
  • Firms over 10 attorneys lose self-serve pricing: above 10 attorneys you cannot use the online configurator and must negotiate with a sales rep, where pricing is bundled with existing Westlaw/Practical Law contracts and is not publicly listed.
  • Practical Law is another line item: the Practical Law Dynamic Tool Set with CoCounsel Essentials plan adds Practical Law's content as a separate bundle. Firms wanting both Westlaw research and Practical Law guidance generally need CoCounsel Legal (complete access), the highest tier.
Tip

Ask your CoCounsel by Thomson Reuters sales rep about these costs upfront. Getting them in writing before signing can save you from surprise charges later.

CoCounsel by Thomson Reuters Pricing FAQ

01 How much does CoCounsel cost?

Thomson Reuters does not publish a fixed CoCounsel price — pricing is configured online by firm size, jurisdiction, and contract term (for law firms up to 10 attorneys) or quoted by a sales rep for larger firms. As a reference point, the Westlaw Advantage with CoCounsel Essentials plan for a solo attorney with All States & Federal coverage is $639.20/user/month on a 1-year term, or $639/user/month on a 3-year term (18% savings), per Thomson Reuters' public configurator in June 2026. AI-only CoCounsel Essentials is the lowest tier and CoCounsel Legal (complete access) is the highest.

02 What are the CoCounsel plans?

There are four plans. CoCounsel Essentials is the AI assistant on its own (research, drafting, document review, summaries, timelines, agentic workflows). Westlaw Advantage with CoCounsel Essentials adds Westlaw primary-law research, KeyCite, and litigation tools. Practical Law Dynamic Tool Set with CoCounsel Essentials adds Practical Law's expert-created content. CoCounsel Legal is complete access to all of the above.

03 Why can't I find a CoCounsel price list?

Thomson Reuters prices CoCounsel through an online configurator rather than a published price sheet. You select your sector, number of attorneys, jurisdiction(s), and term, and the tool returns a price. Online self-serve pricing is available for law firms with up to 10 attorneys; firms above that are quoted by a sales representative.

04 Is CoCounsel the same as Casetext CoCounsel?

It is the successor. Thomson Reuters acquired Casetext (the original CoCounsel) in 2023 and retired the standalone Casetext product on March 31, 2025, integrating the technology into its CoCounsel Legal plans. If you previously used Casetext CoCounsel, you are now on Thomson Reuters' CoCounsel.

05 Does CoCounsel have a free plan or trial?

There is no permanent free plan. Thomson Reuters offers product demonstrations for prospective customers, but ongoing use requires a paid subscription. Confirm current trial availability directly with Thomson Reuters.

06 How do contract terms affect the price?

CoCounsel plans are sold on 1-, 2-, or 3-year terms, and longer terms lower the per-month price. Thomson Reuters' configurator showed a 12% discount on a 2-year term and an 18% discount on a 3-year term versus the 1-year rate.

07 Does the price change by jurisdiction?

Yes. The Westlaw Advantage and CoCounsel Legal plans include primary-law coverage for the circuits or jurisdictions you select, and the price scales with that coverage. The figures cited here use All States & Federal coverage; narrower coverage can cost less.

08 How does CoCounsel compare to Harvey AI?

CoCounsel is sold by Thomson Reuters with deep Westlaw and Practical Law integration and self-serve online pricing for smaller firms. Harvey AI targets larger firms with custom-trained models and typically requires enterprise seat minimums and annual contracts. Firms already invested in Westlaw often find CoCounsel the more natural fit.
