CoCounsel Pricing: Complete Breakdown for 2026

All figures are the total monthly cost for a five-attorney firm, All States and Federal, on a one-year term. These figures use one fixed setting for comparison. Adjust the configurator for your own number.

Thomson Reuters acquired Casetext in 2023 and rebuilt its AI product into CoCounsel. Thomson Reuters shut down the standalone Casetext platform on April 1, 2025, before launching CoCounsel Legal in August 2025. The history explains why CoCounsel pricing is hard to pin down.  

CoCounsel's best features run on Westlaw, which is priced separately. So your real cost is the tool, plus a Westlaw subscription, implementation, and a multi-year contract. 

This breakdown maps the true all-in cost before you take a sales call.

How CoCounsel Structures Its Plans and Pricing

CoCounsel sells through four configurator tiers plus a pay-per-task option. The difference between them comes down to how much Thomson Reuters content and functionality you unlock.

• CoCounsel Essentials includes the core AI assistant.
• Westlaw Advantage with CoCounsel Essentials adds Westlaw primary law and KeyCite.
• Practical Law Dynamic Tool Set with CoCounsel Essentials adds Practical Law resources.
• CoCounsel Legal includes the full suite, including Deep Research and agentic workflows.

CoCounsel requires an annual contract commitment, with pricing negotiated around firm size, seat count, and usage scope. The configurator offers multi-year discounts of about 12% for two years and 18% for three (Thomson Reuters configurator, June 2026). 

For firms with more than ten attorneys, CoCounsel charges enterprise per-seat pricing that requires direct sales engagement with the Thomson Reuters team.

Per-Plan Pricing Estimates

CoCounsel Essentials, the entry plan, costs about $1,464 per month for a five-attorney firm on a one-year term (Thomson Reuters configurator, All States and Federal). It includes the AI assistant only, without Westlaw content. CoCounsel On Demand is a pay-per-task option, but pricing isn’t publicly listed and requires a sales quote.

The Westlaw Dependency: Your Real Total Cost

CoCounsel Legal combines three separate Thomson Reuters products: CoCounsel Essentials, Westlaw Advantage, and the Practical Law Dynamic Tool Set. Looking at their individual prices shows the bundle's value.

For a five-attorney firm on a one-year term, the separate monthly costs are:

• CoCounsel Essentials (AI assistant): $1,464/month
• Westlaw Advantage: $1,324/month
• Practical Law Multi-Practice Premium with Dynamic Tool Set: $1,072/month
• Westlaw Edge(alternative to Advantage): $688.00/month
• Practical Law, Drafting and Negotiating (entry tier): $621.60/month

Source: Thomson Reuters configurator, All States and Federal jurisdiction. Figures are the total for five seats. Adjust headcount, jurisdiction, or term directly on the configurator for your own number. Online pricing stops at 10 attorneys. Above that, you contact sales.

Bought separately at our standard setting, those parts run about $3,860/month ($1,464 + $1,324 + $1,072). Bundled as CoCounsel Legal, the same stack costs $2,461.60/month, roughly $1,400/month less.

CoCounsel Pricing Table: Plans and Estimated Costs

The pricing figures below use one consistent setup from the Thomson Reuters configurator: a five-attorney firm, All States and Federal jurisdiction, and a one-year term. Each price shows the total monthly cost for all five seats, making the plans easier to compare.

Your actual cost will vary based on your firm size, jurisdiction, and contract length. You can adjust those details in the configurator to see updated pricing. Online pricing is available for firms with up to 10 attorneys. Larger firms need to contact Thomson Reuters directly.

What Happened to Casetext Subscribers After the Acquisition?

When Thomson Reuters shut down the standalone Casetext platform on April 1, 2025, existing subscribers moved to the current Thomson Reuters pricing.

In an r/Lawyertalk thread about the shutdown, holders of older "for life" Casetext rates described being moved to Westlaw Classic on one-year promotional terms, with no guarantee that their original pricing would be retained at renewal. One subscriber locked in at $62.30/month reported being quoted $70/month on a one-year promo. 

What Buyers are Saying: CoCounsel's Most Cited Pricing Concerns

Some attorneys note that CoCounsel does not include Westlaw editorial case synopses, which may require a separate Westlaw or Lexis subscription for certain research workflows. 

Comparison analyses mention friction when switching between the Microsoft Word add-in and web portal, which can affect efficiency. At enterprise per-seat rates, the time lost to switching interfaces is a real drag on return on investment (ROI).

Some users have also flagged challenges when working with very large documents, making it worth testing CoCounsel with your typical due diligence materials before committing. 

Additionally, CoCounsel's pay-per-task On Demand tier has no published rate. Thomson Reuters quotes it only through sales. Buyers can't model per-matter costs up front, so the tier marketed as the low-commitment option is the hardest to budget for.

CoCounsel's Hidden Costs: What the Plan Price Doesn't Cover

Even at $2,461.60 a month for five attorneys, CoCounsel Legal's subscription is only the line item you can see. The real first-year cost layers on research content you may still need to license, set up, and onboarding are billed separately, and multi-year terms that lock in your spend.

When CoCounsel's Core Features Require Extra Subscriptions

The base CoCounsel Essentials tier is a more limited product than CoCounsel with full content access. Without Westlaw or Practical Law, you lose primary-law search, KeyCite validation, and the content that powers Deep Research. Many firms maintain a parallel research subscription, paying twice to cover a single workflow.

Multi-Year Contract Terms and Renewal Risk

The 2- and 3-year discounts (roughly 12% and 18%) lower your per-seat cost but increase your exposure if rates climb at the end of the term. Thomson Reuters contracts can carry annual escalator clauses. CoCounsel offers volume-based discounts for larger deployments above a defined seat threshold, but make sure to lock in a renewal-rate cap before you sign.

Onboarding, Training, and Integration Costs

CoCounsel requires a dedicated implementation and onboarding period that adds professional services cost to your first-year total. Connecting it to your document management system (DMS) or Microsoft 365 tools requires IT time, training, and workflow configuration, which are often billed separately from the seat price. 

Build a realistic implementation cost estimate into your legal AI total cost of ownership (TCO) model before you approve the deal.

Does CoCounsel Offer a Free Trial?

No. CoCounsel does not offer a permanent free plan or a self-serve free trial. Instead, Thomson Reuters runs evaluations through demos and sales-managed pilots. The lowest-commitment entry point is the On-Demand option, which uses a pay-per-task model.

CoCounsel offers a pilot program that lets law firms evaluate its capabilities before signing a full enterprise contract, but access to the Westlaw-integrated experience runs through that managed process rather than a one-click signup. 

Is CoCounsel Worth the Price? An Honest Assessment

CoCounsel’s value depends largely on whether your firm already uses Westlaw. 

For research-heavy litigation teams, yes. CoCounsel generates measurable ROI by cutting the attorney hours spent on research, drafting, and document review. It positions itself as a premium enterprise tool backed by Thomson Reuters' institutional credibility. 

CoCounsel fits best in BigLaw, mid-size firms, and large in-house legal teams, where it can also cut outside-counsel spend on document-heavy matters.

For contract-focused teams without research needs, no. The bundled Westlaw cost is hard to justify, and CoCounsel alternatives make more sense.

CoCounsel Pricing vs. the Alternatives

CoCounsel falls in the mid-to-high range for legal AI tools, but its effective cost is higher than the headline per-seat price due to the required Westlaw subscription. The table below compares it with alternatives like Harvey AI, Spellbook, Lexis+ with Protégé, and Ironclad.

Note: Competitor figures are estimates drawn from third-party sources. Most of these vendors don't publish pricing publicly, so contact each platform directly for an accurate quote.

‍

‍

CoCounsel figures are per-user equivalents from the Thomson Reuters configurator (5 attorneys, All States and Federal, 1-year): CoCounsel Essentials ≈ $293/user, CoCounsel Legal ≈ $492/user. Figures for Harvey AI and Ironlad are third-party estimates verified in 2026. Pricing sources vary by platform and should be confirmed directly with each vendor at the quote stage.

CoCounsel only looks fully comparable when you factor in the Westlaw bundle. On a standalone basis, it may look similar to other tools, but the overall ecosystem requirements set it apart from competitors like Harvey AI and Lexis+ with Protégé.

Our CoCounsel vs Harvey breakdown digs into the enterprise end of that spectrum.

How to Negotiate a Better CoCounsel Deal

CoCounsel pricing is negotiable, especially for firms already buying other Thomson Reuters products. The strongest deals usually come from how you structure the purchase, not just from asking for a discount.

• Bundle with Westlaw renewals: Larger firms often secure CoCounsel at a reduced cost (or included) when it’s tied to a multi-year Westlaw contract.
• Use competitor pricing as leverage: Bringing quotes from tools like Harvey AI helps strengthen negotiation power.
• Negotiate both term length and renewal caps: Multi-year discounts matter less if renewal escalators aren’t controlled.
• Start with On Demand or a pilot: Testing usage first gives you proof of value before committing to full seats or enterprise pricing.

Why Contract Teams Consider Spellbook Instead

If your work is contracts rather than case law research, CoCounsel's Westlaw dependency is a cost you may never use. Spellbook delivers contract drafting and review without requiring a separate research database subscription.

• No bundling requirement. Spellbook pricing is a single per-seat subscription with no content add-on, so a contract team avoids the $300–$600+/user/month bundle math CoCounsel can require.
• Unified Word-native workflow. CoCounsel splits work between a Word add-in and a separate web portal. Spellbook runs entirely inside Microsoft Word.
• Real-time market data. Spellbook's Compare to Market benchmarks your terms against thousands of similar agreements, giving a data-backed answer to "is this market?" without a separate research subscription. 

If contract work is your focus, Spellbook's 7-day free trial lets you test it on your own documents.

Frequently Asked Questions

How Much Does CoCounsel Cost per Month?

CoCounsel costs $1,464 to $2,461.60 per month for a five-attorney firm on a one-year term. CoCounsel Essentials at the low end, full CoCounsel Legal at the top, or roughly $293 to $492 per user. CoCounsel On Demand is pay-per-task and not publicly priced. Firms with more than 10 attorneys must contact sales. Adjust the configurator for your own headcount and term.

Can You Use CoCounsel Without a Westlaw Subscription?

Yes, through the CoCounsel Essentials tier or pay-per-task On Demand, but you lose the features most lawyers want. Without Westlaw, you have no primary-law search, no KeyCite citation validation, and a weaker Deep Research experience. For most practitioners, the standalone AI layer is more a gateway to the full bundle than a complete product on its own.

What Happened to Casetext Pricing After the Thomson Reuters Acquisition?

Thomson Reuters acquired Casetext in 2023 and retired the standalone platform on April 1, 2025. Legacy subscribers were migrated to Thomson Reuters products, and those who held older "for life" Casetext rates reported being moved onto fixed-term promotional pricing with no guaranteed renewal rate. 

For buyers today, past Casetext pricing should not be treated as a benchmark. Promotional offers may change, and renewal pricing may align more closely with Thomson Reuters’ standard rates.

How Do Multi-Year CoCounsel Contracts Affect Total Cost?

Multi-year terms lower your per-seat cost (12% off for two years and 18% for three, per the configurator), but they raise renewal risk if rates escalate at term end. Thomson Reuters contracts can include annual escalator clauses. Negotiate the discount and a firm renewal cap in a single conversation, so the multi-year savings aren't erased later.

Is CoCounsel a Good Fit for Small Law Firms?

It depends on whether you already pay for Westlaw. If you do, CoCounsel is a reasonable incremental add-on for research-heavy work. If you don't, the full-stack commitment is steep, and purpose-built tools with transparent pricing and no bundling requirement are often a more practical starting point for a small practice.
