Legal research and drafting AI grounded in Westlaw and Practical Law content, with published starting prices from $340.85 a month for small firms.
Firms that already pay for Westlaw or Practical Law and want AI answers grounded in that licensed content rather than a general model reading their own files. It is the only vendor in this set publishing real starting prices, and small firms of 1-10 attorneys can buy online without a sales call. Litigation teams get named tools: Deep Research, Litigation Document Analyzer, Westlaw Brief Builder and Tabular Analysis across up to 10,000 documents.
Firms over 10 attorneys cannot use the published prices at all — the buy links are scoped to 1-3 and 4-10 attorney brackets and above that you contact a sales rep, so the headline figures are a small-firm shop window, not your quote. The published monthly amounts are also 'starting at' and the plan pages never say whether they are per user or per firm, which makes budgeting for a growing team guesswork. Non-US firms should verify coverage before committing, because jurisdiction coverage is not stated on the product or features pages and the content anchors are Westlaw and Practical Law.
Pros
Cons
Thomson Reuters publishes starting monthly prices: CoCounsel Essentials from $340.85, Practical Law Dynamic Tool Set with CoCounsel Essentials from $882.30, and full CoCounsel Legal from $1,694.90. These are 'Starting at' figures and the pages do not say whether they are per user or per firm. Online pricing is stated to be available to new customers only.
Yes. Thomson Reuters publishes a free 24-hour trial of CoCounsel Legal with the heading 'Try CoCounsel Legal, free for 24 hours' and states 'Full access for 24 hours', 'No credit card needed' and that the trial begins when you first log in. CoCounsel Essentials has a separate request-trial page whose length is not published.
No. Thomson Reuters states on the CoCounsel product page that data remains secure and private and 'we never use it to train underlying models'. The same page says CoCounsel is 'SOC 2 and ISO 42001 certified'. What is not published on those pages is where customer data is hosted, so ask for a data residency commitment in writing if that matters to your team.
Thomson Reuters names iManage, Netdocuments, Sharepoint, HighQ, DeepJudge and Box for document management, plus Smokeball, Litify and Supio, and Word, Outlook and Teams on the Microsoft side. Claude is also named. Workspaces keep documents, templates and matter history together per matter, and Tabular Analysis can 'Review up to 10,000 documents against 100 questions'.
