Seamless integration across workflows
When AI tools require too much behavioral change, adoption can become a barrier to law firms. CoCounsel Legal fits directly into familiar workflows, enabling lawyers to quickly benefit from AI without disruptive change management processes.
Enhance the way you get work done in one continuous workflow with:
- Document review: Imagine reviewing 500 pages of contracts in an M&A deal. What used to take days now takes hours, with CoCounsel identifying key terms, flagging inconsistencies, and surfacing potential risks.
- Legal research: When you’re facing a complex multi-jurisdictional question, CoCounsel can simultaneously analyze case law across multiple jurisdictions, delivering relevant precedents with proper citations in minutes.
- Contract drafting: Starting a new contract from scratch? CoCounsel suggests trusted starting points from Practical Law, helping you draft faster while maintaining quality.
CoCounsel Legal seamlessly integrates these tasks by uniting the AI capabilities in CoCounsel Essentials with Westlaw Precision, Practical Law Dynamic Tool Set, Microsoft 365, and available DMS integrations. This unified experience addresses what legal professionals need most: the ability to supercharge their workflows from beginning to end without toggling between multiple tools or copying and pasting between systems.
CoCounsel Legal also delivers an end-to-end solution directly within Microsoft Word, eliminating the need to learn new interfaces or disrupt established workflows. You can easily find the best starting point and surface trusted recommendations for contracts and documents while staying in the environment you already use daily.

Proven results that change how firms operate
Customers report that CoCounsel reduces the time needed for document review and contract drafting by 63%. This translates directly to more time for strategy, client relationships, and taking on more cases.
In a survey of Westlaw Precision with CoCounsel customers, they found twice as many relevant cases in the same amount of time compared to non-generative AI solutions. 85% of CoCounsel customers agree that it helps them find more key pieces of information than manual review alone.
For attorney Diane Haar of Hawaii Disability Legal Services, these efficiency gains have a direct impact on her ability to serve clients who need her expertise. With Westlaw Precision with CoCounsel’s AI-Assisted Research feature, she can tackle complex legal research at a productive rate and support more clients without increasing costs. As she puts it, “The time savings is massive, and time is money.”
Built on 225 years of legal expertise
Thomson Reuters is a trusted, long-standing partner and provider of legal solutions, and this heritage directly influences how CoCounsel Legal delivers results. The platform is grounded in the authoritative content and expertise of Westlaw and Practical Law, which means every answer comes from sources your firm already knows and trusts rather than from scraped web content.
Research results always provide citations, so you can easily verify output and present it confidently to clients and courts. Expert curation comes from Practical Law’s team of attorney-editors and subject matter experts who understand the nuances of real-world practice. They ensure every result links directly to authoritative sources you can rely upon in client work and court filings.
This foundation of trust resonates with legal professionals who already rely on solutions from Thomson Reuters. As Kiersty DeGroote, associate attorney at Bochetto & Lentz explains: “We knew that Westlaw had the database we needed. We knew it had the cases we needed. We knew there were tools already useful to us. So, when CoCounsel merged with Westlaw, it just made perfect sense to continue to use those products together.”

Professional-grade security in a trusted partnership
Many AI tools don’t meet the data security and privacy standards that top-tier law firms and government agencies demand when handling sensitive legal matters. Generic AI platforms often operate under consumer-grade security frameworks that expose firms to unacceptable risks, from potential data breaches to unauthorized access to confidential client information.
CoCounsel Legal delivers enterprise-grade security features specifically designed for the legal profession’s stringent requirements. All customer data is encrypted in transit and at rest, processed on private, eyes-off infrastructure, and never used to train third-party models. It holds industry-standard compliance certifications including SOC 2 and ISO 27001, with no data retention or cross-client contamination to protect sensitive legal matters.
Achieving better legal work
With CoCounsel Legal in your corner, you’ll be empowered to produce higher-quality work to better serve your clients and organizations. Reclaim the time you’ve been spending on tedious and repetitive tasks and spend it on the strategic, creative, and interpersonal work machines can’t do.
