Legal AI pricing, checked against the vendor pages
Thomson Reuters does not publish a price list for CoCounsel. Every figure you find online is either a quote someone received or an estimate, which is why the numbers on review sites contradict each other by a factor of six. Here is what is actually verifiable, what sets your quote, and what you pay for a published flat rate instead.
Every CaseClerk price on this page is a published rate you can read on our pricing page, not a quote.

Thomson Reuters does not publish a CoCounsel list price. Pricing is generated per firm: new customers at smaller firms get an online self-serve quote after entering their role and firm details, and larger firms are quoted by a sales representative. Thomson Reuters does state two discounts on its own pages, 12 percent off a 2 year subscription and 18 percent off a 3 year subscription.
That means nobody can honestly tell you your CoCounsel cost without running your own quote. Public estimates from third party review sites range from roughly $104 to $639 per user per month, and Thomson Reuters confirms none of them. If a flat published price matters more to you than a negotiated one, CaseClerk charges $99, $249 or $499 per month with the page allowance printed next to each tier.
Fix your headcount and tier first
Decide how many attorneys genuinely need it and whether you need Westlaw or Practical Law content at all. Those two answers move the price more than anything you can negotiate.
Run the self-serve quote
Thomson Reuters offers online pricing to new customers at smaller firms. Enter your role and firm details on the CoCounsel plans and pricing page and read the number it returns. That is the only figure that applies to you.
Ask for the 1 year total, not the monthly
Per user per month hides the commitment. Ask for the total contract value on a 1 year term, then on 2 and 3 years with the stated 12 and 18 percent discounts applied, and compare the three.
Price the job, not the brand
Before you sign, run one live matter through a flat priced tool and see how much of the work was actually document reading. If it all was, you do not need a research subscription attached to it.
These are different products, and CoCounsel is the bigger one. This table is for deciding which job you are buying for.
| CoCounsel (Thomson Reuters) | CaseClerk | |
|---|---|---|
| Price visibility | No published list price. Self-serve quote for new customers at smaller firms, sales quote above that | Published: $99, $249 and $499 per month on the pricing page. A fourth Enterprise tier is quoted, and we will say so rather than pretend otherwise |
| Billing model | Per user, per month, on an annual or multi-year term | Flat monthly account price with a monthly page allowance |
| Commitment | Annual, with 12 percent off at 2 years and 18 percent off at 3 years | Month to month, or a year for the price of six months |
| Case law research | Yes, with Westlaw and Practical Law content. This is where CoCounsel is genuinely stronger | No. CaseClerk does not do case law research and does not claim to |
| Drafting | Yes, drafting and agentic workflows in the CoCounsel Legal tier | No. It answers questions about documents you upload |
| Reading a whole matter and citing sources | Yes | Yes, and every answer names the document it came from |
| Try before you buy | 7 day trials and demos are available through Thomson Reuters | 25 pages and up to 5 documents, no card |
| Best for | Firms that want research, know-how and AI bought as one ecosystem, and can sign a multi-year contract | Firms whose real problem is a 400 page file nobody has time to read, at a price they can read off a page |
CoCounsel plan names and the stated term discounts are taken from Thomson Reuters pages. The per user figures circulating on review sites are third party estimates and are not confirmed by Thomson Reuters. Verified September 2026.
Pay for CoCounsel if research is the bottleneck
If your attorneys spend their day in Westlaw and you want the AI sitting on top of primary law and Practical Law know-how, the bundle is the point and the price is defensible.
Pay for CoCounsel if you are already in the stack
A firm that already carries Westlaw is pricing an add-on rather than a new platform. That is the cheapest version of this decision and the one most likely to make sense.
Think again if the work is document reading
Reviewing a production, finding who is named in an intake packet, or pulling dates out of a medical file are document jobs. They do not need a research subscription attached, and that is most of the bill.
Think again if a 3 year term is the only way it fits
If the price only works at 18 percent off across three years, you are betting on a 2026 vendor choice through 2029 in the fastest moving software category in law. Start with something you can leave.
We checked the public estimates while writing this page. They do not just differ, they disagree so widely that at least most of them have to be wrong. The spread itself is the useful finding, so here it is rather than a single confident number we cannot stand behind.
| What third party sites report | Implied cost for one user |
|---|---|
| A range of roughly $104 to $639 per user per month across four plans | $1,248 to $7,668 a year |
| About $225 per user per month for the document focused tier | Around $2,700 a year |
| Roughly $75 to $500 per user per month depending on tier | $900 to $6,000 a year |
| Around $4,500 per user annually for the document tier | $4,500 a year |
Those are four different answers to one question, published by sites that all sound certain. None of them is a Thomson Reuters price, because Thomson Reuters does not publish one. The lesson for a buyer is narrow and practical: treat every CoCounsel figure you read, including the ones in that table, as somebody else’s quote, and only trust the number the configurator returns for your own firm.
People still search for CoCounsel Core pricing, and it is worth saying why that name is hard to price. Core dates from the Casetext era, before Thomson Reuters folded the product into its own lineup. The plan names on the Thomson Reuters pricing pages today are CoCounsel Essentials, Westlaw Advantage with CoCounsel Essentials, Practical Law Dynamic Tool Set with CoCounsel Essentials, and CoCounsel Legal.
If you were quoted for Core at some point, you are not comparing like with like against a current quote, and the same goes for older Casetext pricing you may have on file. Ask for the current tier name in writing before you compare anything.
This matters more than a naming footnote. Essentials is the assistant without Westlaw content. The two middle tiers attach research or know-how. CoCounsel Legal is the full ecosystem. Two firms can both say they pay for CoCounsel and be paying for very different things, which is another reason the public numbers scatter the way they do.
Quote-based pricing is not a problem as long as you make the quote comparable. These are the questions that change the total, asked in a form that is hard to answer vaguely.
The last one catches firms out most often. Per user licensing is comfortable while you are hiring and expensive the moment you are not.
Most of what a firm wants from legal AI on any given Tuesday is not research. It is a file that arrived too big to read before a deadline. Who is named in this intake packet. What did the treating physician say about causation. Which of these 300 pages mentions the indemnity cap. Every one of those is answered from documents the firm already has.
That is the job CaseClerk is built for, and it is why the pricing looks different. You upload the documents for one matter into a vault, ask questions in plain English across all of them, and get answers that name the source document so you can check them. Up to 1,000 documents per case, across 18 file formats including scanned PDFs, Word, Excel and images.
The price is on the page and it is not per user: $99 a month for 2,500 pages, $249 for 10,000, $499 for 30,000, and a year costs the same as six months. There is no free plan, because a renewing free tier just removes the reason to pay, but there is a real trial: 25 pages and up to 5 documents, no card, on your own file. If you are weighing a multi-year research contract, spending twenty minutes finding out how much of the work was document reading is the cheapest due diligence available.
If research really is the job, the vendor comparison worth reading first is our breakdown of the best AI legal research tool for law firms, which compares Westlaw Precision AI, Lexis+ AI and vLex Vincent on coverage and citation checking. If the review work in front of you is contracts rather than case files, our AI contract review software page covers that use case directly, and firms pricing a second layer for intake should read the conflict check software for law firms page.
There is no published answer. Thomson Reuters prices CoCounsel per firm, with an online self-serve quote for new customers at smaller firms and a sales quote for larger ones. Third party sites report figures from roughly $104 to $639 per user per month, none confirmed by Thomson Reuters. Run the configurator for your own firm.
CoCounsel is billed per user, and the monthly figure depends on tier, headcount and contract length, so it varies between firms. Thomson Reuters does not print a monthly rate. Ask for the total contract value for your user count instead, because a per user per month number hides the annual commitment underneath it.
Small firms are the group Thomson Reuters routes to online self-serve pricing, so you can get your own number in a few minutes without a sales call. Enter your role and firm details on the CoCounsel plans and pricing page. Expect the tier you pick, and whether it carries Westlaw content, to matter more than headcount.
CoCounsel is a Thomson Reuters product, the same company behind Westlaw, and the two are sold both separately and bundled. CoCounsel Essentials is the assistant without Westlaw content, while Westlaw Advantage with CoCounsel Essentials and CoCounsel Legal attach research content. Which one you are quoted changes the price substantially.
Core is the earlier Casetext era tier name and is not what the current Thomson Reuters pricing pages are built around. Today the lineup is CoCounsel Essentials, two Essentials bundles with Westlaw or Practical Law content, and CoCounsel Legal. Ask for a quote against a current tier name so you are comparing like with like.
Yes, and this is one of the few numbers Thomson Reuters states publicly: 12 percent off a 2 year subscription and 18 percent off a 3 year subscription. Weigh that against locking a legal AI choice for three years in a category that is changing quickly. An 18 percent saving on the wrong tool is not a saving.
If the work is reading documents you already hold rather than researching case law, yes. CaseClerk publishes flat pricing at $99, $249 and $499 per month with page allowances of 2,500, 10,000 and 30,000, and answers name the source document. It does not do case law research, so it is not a replacement for the Westlaw side.
Sometimes. Thomson Reuters states that the pricing shown online is for new customers only, and the self-serve route is aimed at smaller firms. Existing customers and larger firms are directed to a sales representative. If you are already subscribed to anything in the stack, expect a conversation rather than a configurator.
