Westlaw Brief Builder (US)

A transformation of research and drafting, Westlaw Brief Builder helps litigators move from research and issue analysis to first-draft brief creation while validating authority along the way. It follows a workflow purpose-built for briefs, guiding the drafter through each stage of the process in a way that litigators actually think and work — an organized, connected experience developed and validated by attorneys. Powered by Westlaw Deep Research, KeyCite, and Practical Law — authority no other legal AI can match — it proposes relevant facts, arguments, and supporting authority while keeping lawyers firmly in control of strategy, legal theory, and final decisions. And because output is verified against the law and the facts, then surfaced for review and confirmation, Westlaw Brief Builder delivers briefs not only faster, but briefs you can stand behind.

Global Connected Platform

Firm Document Management Connectors via Syncly (US, UK & Canada)

Admins can now connect CoCounsel Legal directly to a firm’s document management system through new Syncly connectors, including iManage on-prem, iManage Cloud, and SharePoint. Once connected, CoCounsel can access and act on firm content directly, with a connector icon appearing for end users wherever a connection is active — simplifying the ability to bring trusted firm documents into AI-assisted research, analysis, and drafting without leaving the platform.

Expanded CoCounsel Legal MCP with Claude (US)

CoCounsel Legal’s MCP connection with Claude is expanding. What started with Deep Research now extends to research, analysis, and drafting, bringing more of CoCounsel Legal’s fiduciary-grade AI capabilities directly into Claude. Lawyers can describe a matter in plain language inside Claude, and CoCounsel Legal plans the work — reasoning from authoritative Westlaw primary law, trusted Practical Law guidance, and a firm’s own knowledge — and returns cited, traceable work product without leaving Claude.Tabular Analysis Enhancements in CoCounsel Legal (US)

Tabular Analysis is evolving. In the newly launched version of CoCounsel Legal, bulk document review is now built directly into the workspace — no more exporting files or rebuilding a separate database to review a subset. Creating and editing tables is simpler too, with a redesigned experience built from direct customer feedback, and multiple tables can now share the same set of files instead of duplicating work for each one. Tabular Analysis also runs by default on Thomson, �������� own purpose-built legal AI model — the organizational and technical foundation for a more connected CoCounsel Legal.

Built for How You Work

Verbatim Extraction in Tabular Analysis (US, UK & Canada)

Attorneys building disclosure schedules, privilege logs, and red-flag memos need exact clause language, not paraphrases. A new Verbatim column type in Tabular Analysis returns exact source text instead of AI-generated summaries, so attorneys no longer need to reopen the original document to re-quote a clause. Users select “Verbatim” when configuring a column and describe what to pull; CoCounsel returns the exact language from the source, validated against the document, and clicking any cell opens the source with the precise span highlighted for verification. Exports carry the verbatim text into Word and Excel with quotation marks already applied, ready for partner review and closing binders.

Judicial Experience on CoCounsel (US)

A new, personalized CoCounsel environment is now available for trial, appellate, and supreme courts. When judges or clerks activate the Judicial setting, the application adapts to their role with a neutral-stance default and a suite of curated judicial workflows, including pro se brief standardization, statute of limitations checks, cross-brief issue synthesis, and case fact drafting — every output grounded in trusted Westlaw and Practical Law content, with hyperlinked citations and KeyCite verification for auditable, defensible decisions.

Thomson – New Proprietary LLM (US, Canada & UK)

Thomson, the first proprietary large language model built by �������� draws on decades of proprietary content from Westlaw, Practical Law, Checkpoint, and Reuters plus hundreds of subject matter experts to reach Fiduciary-Grade standards at a fraction of typical cost. Early evaluations, including external testing by legal and AI academics, put Thomson on par with leading frontier models, particularly in instruction-following and domain-specific legal reasoning, and the model is now being deployed first in Tabular Analysis within CoCounsel Legal, with plans to extend Thomson across the legal and tax portfolio alongside additional sovereign AI options.

Deep Research Verify in Practical Law Premium (UK)

Deep Research Verify is now available in Practical Law Premium, integrated directly into the existing Deep Research workflow. Verify lets users review specific AI-generated legal assertions against relevant supporting passages from underlying Westlaw UK and Practical Law sources, with source support displayed inline alongside the original report. By reducing manual cross-referencing and providing a direct route to further research, Verify helps legal professionals assess AI-generated research more efficiently, transparently, and confidently.

Deep Research Verify in CoCounsel (UK)

CoCounsel UK now offers the ability to verify a Deep Research report directly within the platform. Deep Research Verify checks a Deep Research report against Practical Law and Westlaw UK’s authoritative sources, confirming citations are accurate rather than hallucinated and surfacing additional relevant law the report may have missed — moving users through verification faster and giving them more links to explore for further research.

Westlaw Advantage Canada — Parallel Search (Canada)

Parallel Search is a new feature in Westlaw Advantage Canada that finds cases with facts or issues similar to a scenario described in plain language — not just documents matching the words in a query. Users describe a fact pattern or issue in a sentence, and Parallel Search surfaces up to 25 Canadian cases with analogous facts or reasoning, helping researchers find true comparators and surfacing analogous outcomes they might otherwise miss, especially on novel or hard-to-phrase issues.

Deep Research Verify in Westlaw Advantage Canada and CoCounsel Legal (Canada)

Deep Research Verify is now available within the Deep Research experience on Westlaw Advantage Canada and CoCounsel Legal. For each assertion in a Deep Research report, Verify presents supporting text from the cited source and flags where support may be lacking, with a clear path for additional manual verification — helping users review AI-generated research with greater confidence and less manual cross-referencing.

For litigators, that matters because some of the most important context in a matter does not begin in a research or drafting tool. It begins in the evidence.��

Documents. Testimony. Facts developed over the course of discovery. The record a lawyer ultimately has to connect to the law and turn into analysis, strategy, and work product they can stand behind. AI should make that process easier.��

This week at ILTACON, �������� and Everlaw announced plans to integrate Everlaw with CoCounsel Legal. The first planned integration will allow mutual customers to bring Everlaw documents into CoCounsel Legal in bulk, making it easier to use litigation and investigation materials across CoCounsel Legal’s research, analysis, drafting, and workflow capabilities.��

For customers, that means less friction between reviewing evidence and doing the legal work that follows.��

For us, it is also one more piece of the broader CoCounsel Legal ecosystem we are building: connecting the systems, content, and tools professionals already rely on so they can move through complex legal work with more continuity and less unnecessary handoff.��

Everlaw brings an important part of that ecosystem into the picture for litigation: the evidentiary record.

Connecting evidence, context, and legal analysis��

A litigator rarely asks a purely abstract legal question. The real question is how the facts, evidence, and applicable law come together: whether a particular document changes the argument, whether testimony is consistent with the rest of the record, or whether the evidence supports the position being put before a court. Carrying that context through the legal workflow is essential to making AI genuinely useful in litigation.��

CoCounsel Legal brings together research, analysis, drafting, and other legal workflows with authoritative content from Westlaw and Practical Law. But in litigation, authoritative legal information is only one part of the picture. The evidentiary record matters just as much.��

Bringing those worlds closer together can make AI much more useful in the day-to-day practice of law.��

By reducing the need to manually move documents between systems, we can help lawyers spend less time on those handoffs and get to the substantive legal work faster.��

Moving from evidence to analysis with less friction��

Consider what happens when a litigation team identifies a set of important documents during discovery.��

Those materials may already have been collected, reviewed, organized, and understood within an eDiscovery platform. But when the team moves into other parts of the legal workflow, that context does not always move with them.��

That can mean exporting documents, uploading them into another environment, and reconstructing parts of the matter before the lawyer can move forward. Every handoff creates friction.��

The planned Everlaw integration is intended to shorten that path. Once Everlaw documents are available in CoCounsel Legal, lawyers can apply CoCounsel Legal’s research, analysis, drafting, and workflow capabilities to those materials, creating a more direct connection between the evidentiary record and the legal work that follows.��

It is also exactly the kind of connection we want to keep adding across the CoCounsel Legal ecosystem: bringing more of the places where legal work already happens into a workflow where professionals can research, analyze, draft, and act with the right context around them.��

Connected AI still has to meet the standard of legal work��

Making more information available to AI cannot mean lowering the standard for what comes out. The lawyer is still responsible for the argument. Still responsible for the citation. Still responsible for understanding whether the evidence supports the conclusion.��

That is why verification, transparency, and professional judgment matter so much. At ��������, we describe this standard as Fiduciary-Grade AI: AI designed for high-stakes professional work, grounded in authoritative information and built so professionals can review, verify, and ultimately stand behind the work it helps produce.��

Connecting more of the matter into that workflow should strengthen the lawyer’s ability to exercise judgment, not remove the lawyer from the process.��

Building a broader ecosystem around legal work��

Law firms and legal departments have invested in specialized technology for a reason.��

Evidence may live in an eDiscovery platform. Documents may live in a document management system. Legal research comes from trusted legal sources. Work product may move through several systems before it is complete. AI is not going to make that ecosystem disappear. The opportunity is to make it work together better.��

That is the direction we are taking with CoCounsel Legal. We are building an ecosystem designed to connect the tools, content, and workflows professionals already depend on, while preserving the context, permissions, controls, and trust required for high-stakes work.��

Everlaw is an important addition to that ecosystem because it brings the evidentiary record closer to the research, analysis, and drafting lawyers are already doing in CoCounsel Legal.��

And it is one part of a much broader direction.��

As we continue expanding the CoCounsel Legal ecosystem, we want professionals to be able to bring more of their work, their context, and the systems they trust into a more connected AI experience.��

For customers, that can mean fewer unnecessary handoffs and a more direct path from evidence to insight and work product.��

For the industry, it is another signal of where legal AI is headed. The next generation of legal AI will not just be more capable. It will be built to connect the work around it.��

�������� is working with Google Cloud to connect HighQ with Gemini Enterprise for Legal, giving legal professionals a secure way to bring authorized matter documents, structured data, and workflows into the AI environment where they are collaborating.

The HighQ MCP connection is now live alongside Google Cloud’s announcement of Gemini Enterprise for Legal.

This is an important milestone, but it is also exactly that: one milestone. HighQ is the natural place to begin because it contains the live matter context AI needs to be useful. Over time, we see opportunities to extend more of the trusted capabilities of CoCounsel Legal across the AI environments our customers choose to use.

Why matter context matters

Enterprise AI continues to improve, but legal work has always depended on context. That context is more than documents. It includes structured matter data, workflows, tasks, templates, collaboration history, deadlines, permissions, and the institutional knowledge surrounding a case or transaction. Much of that lives in HighQ.

Law firms and corporate legal departments rely on HighQ to manage matters, collaborate internally and externally with clients and outside counsel, power secure client portals, and organize work that evolves over weeks, months, or years. Connecting HighQ with Gemini Enterprise for Legal allows authorized users to securely access that context without exporting files, copying information between systems, or recreating it somewhere else.

A legal team could ask Gemini Enterprise for Legal to summarize documents in an authorized matter, identify upcoming deadlines from an iSheet, compare structured deal data with underlying agreements, or bring relevant matter information into a draft.

The value is not simply giving AI access to more information. It is giving AI access to the right information, with the governance legal organizations already depend on.

Governance isn’t optional

Legal organizations should not have to choose between adopting new AI capabilities and maintaining the controls their work requires.

The HighQ MCP connection is designed so organizations don’t have to make that tradeoff. Content remains in HighQ. Once a customer securely connects HighQ, users authenticate using their existing HighQ credentials, and existing matter walls; folder permissions, document-level security, and audit logging continue to apply. Gemini Enterprise for Legal can retrieve only the content an individual user is already authorized to access. The connection is read-only, allowing AI to retrieve authorized information without changing the underlying content.

That means organizations can confidently extend trusted matter context into Gemini Enterprise for Legal while keeping governance exactly where it belongs.

Extending CoCounsel Legal into the enterprise AI ecosystem

This announcement is about more than connecting two products.

CoCounsel Legal remains the trusted platform where legal professionals perform complex legal work. It brings together authoritative legal content, customer context, agentic workflows, verification, and human oversight to help professionals produce work they can verify and stand behind.

At the same time, legal teams increasingly collaborate with business colleagues, outside counsel, customers, and partners who may be working in different AI environments.

Open standards like MCP make it possible to extend trusted legal context and capabilities into those environments without requiring organizations to move their work out of CoCounsel Legal or compromise on governance.

Today’s HighQ integration is the first exciting step in that broader vision with Google Cloud.

Building an open ecosystem for trusted legal AI

The future of enterprise AI will not be defined by a single model or a single interface.

Organizations will continue using different AI environments for different types of work. Our role is to ensure that wherever legal professionals collaborate, they can securely access the trusted matter context, authoritative content, and professional capabilities their work requires.

That is why �������� continues to invest in MCPs, APIs, agentic systems, and strategic partnerships across the AI ecosystem.

“Customers have told us they want our AI solutions to connect seamlessly with the trusted systems they already rely on for everyday legal work,” said Satish Thomas, Vice President, Google Cloud. “Working together with ��������, we’re making it easy to bring critical matter context directly into their workflow today, while creating a path toward even deeper integrations over time.”

The launch of Gemini Enterprise for Legal and the HighQ MCP connection demonstrates what’s possible when trusted matter context and enterprise AI are designed to work together. It’s an important step in our collaboration with Google Cloud and another step toward making trusted legal AI available wherever professionals need it, while keeping CoCounsel Legal at the center of how that work gets done.

That is the distinction we had in mind when building Westlaw Brief Builder, a new agentic capability in CoCounsel Legal designed specifically for litigation brief writing. As part of the enhanced CoCounsel Legal experience announced this week, Westlaw Brief Builder transforms research and drafting with AI agents that use Westlaw and Practical Law iteratively with the litigator to produce stronger briefs. AI agents conduct extensive research on the facts, arguments, and authority using Westlaw, Practical Law, and material from the case identified by the litigator. With each iteration, the litigator benefits from that research while remaining in control of the arguments, language, and overall structure of the brief.

Generating polished legal prose is becoming the easy part. AI can produce something that looks like a sophisticated brief in seconds. But the appearance of legal reasoning is not the same as legal reasoning, and in litigation, confusing the two can be dangerous. A brief has to do more than sound persuasive. Its arguments need to be grounded in the record, supported by authoritative law, tested against contrary authority, and strong enough for lawyers to put their names behind.

That is where the real opportunity for AI lies. Not in producing more text, but in helping lawyers do the substantive work required to build defensible arguments more efficiently, while preserving the strategy, judgment, and scrutiny that litigation demands.

The harder question is whether that brief is actually good. That goes far beyond checking whether the cited cases are real. If a lawyer has to reconstruct the research and reasoning behind an AI-generated draft before deciding whether to trust it, much of the promised efficiency disappears.

That is why we built Westlaw Brief Builder to work iteratively with the litigator rather than simply generate a finished document. Its AI agents conduct research at each stage using Westlaw, Practical Law, and matter materials identified by the litigator. The lawyer reviews the arguments, facts, and legal authority surfaced by the system, decides what belongs in the brief, and shapes the work as it develops. The result is not a brief handed to the lawyer for inspection at the end. It is a brief the lawyer has actively built with AI agents throughout the process.

Brief writing starts long before the first draft

Strong briefs are built through a series of interconnected decisions. Litigators need to understand the record, identify the issues that matter, determine which arguments are worth pursuing, research the applicable law, and continually reassess those choices as new facts or authority emerge.

Westlaw Brief Builder is designed around that reality. Its structured, multi-step workflow takes the litigator through intake, argument identification, supporting legal research, argument development, and drafting. At key points, the lawyer reviews what the system has surfaced and makes the strategic decisions about what comes next.

For example, Westlaw Brief Builder can propose potential arguments based on the matter and its initial research, but the lawyer decides which ones to pursue. From there, AI agents can investigate the relevant authority and supporting facts, while the lawyer can add information, refine the reasoning, and determine what ultimately belongs in the brief.

That iterative process becomes particularly important when research begins shaping the argument itself.

Research and drafting should work together

The quality of a legal argument depends on what sits behind it. That is why Westlaw Brief Builder integrates Westlaw Deep Research into the drafting workflow and draws on authoritative Westlaw and Practical Law content.

Once a lawyer determines which arguments to develop, the system can research relevant authority based on those arguments, the facts of the matter, and the applicable jurisdiction. The lawyer can review the authorities surfaced through that research, understand how they support an argument, and decide what should be incorporated into the brief.

Bringing those steps together means research can inform the argument as it develops rather than becoming a separate task before or after drafting. For litigators, that is a more natural reflection of how the work actually happens: research changes arguments, facts change research, and the two evolve together until the lawyer is prepared to stand behind the result.

The bar for AI-assisted drafting should be higher than speed

We are going to see continued innovation around AI-assisted legal drafting, and that is a positive development for the profession. Brief writing is demanding and time-intensive work, and there is enormous potential for technology to help lawyers complete it more efficiently.

But as the market evolves, we should be precise about what meaningful progress looks like. The goal is not autonomous brief generation or removing lawyers from legal reasoning. It is helping lawyers spend less time on unnecessary process while giving them better support for the substantive work that requires their expertise.

That principle is central to how we think about Fiduciary-Grade AI at ��������. In high-stakes professional work, the goal cannot simply be an impressive output. Professionals need authoritative information, transparency into the work supporting the result, and the ability to exercise their own judgment before standing behind it.

Westlaw Brief Builder is one part of the broader CoCounsel Legal experience we are building around that idea. The enhanced CoCounsel Legal brings together research, drafting, firm knowledge, and matter-centric workflows within a single AI-powered environment, helping professionals move from a legal question toward defensible work product without treating each stage of work as a disconnected interaction.

Westlaw Brief Builder takes that approach deeper into one of litigation’s most consequential workflows. It is designed to help lawyers develop arguments, find and evaluate relevant authority, create a stronger draft, and shape the work as it develops, while preserving the professional judgment that makes a brief more than simply AI-generated text.

AI can make drafting faster. The standard we should be aiming for is whether it helps lawyers produce better, more defensible work they are prepared to stand behind.

Now, we’ve got the answer – by the numbers. �������� recently commissioned Forrester Consulting to conduct a study to examine the potential return on investment (ROI)law firms can realize by deploying CoCounsel Legal, our AI solution, which brings together legal research, essential workflow automation, intelligent document search and AI-powered legal assistance in a single platform.

Real-World Scenarios, Concrete Results

To produce the analysis, researchers conducted detailed interviews with senior law firm decision-makers who’ve been using CoCounsel Legal for the past several months to understand exactly how they are working with AI inside their firms, what the real-world impacts have been on their business, and the bottom-line costs and benefits linked to their investments in AI. The results of those interviews were then combined to create a single composite organization – a multi-practice law firm with 500 attorneys – and financial impacts were extrapolated over a three-year period.

The research puts some hard numbers behind a value proposition that, until now, has been hard to quantify. It answers the critical question: How exactly are AI-driven efficiency gains creating new growth opportunities for law firms?

Following are some of the key findings for the composite organization:

• Return on investment: 400%
  The headline finding of the analysis is that the total ROI of the composite law firm investment in CoCounsel was 400%, meaning the return after three years, minus costs involved with acquiring the technology, onboarding, and training staff, is five times greater than the initial investment. In this example, that translates to a total of $18.3 million in total value over three years.
• Incremental revenue from increased matter capacity: $20.3 million
  Contrary to much of the recent rhetoric around professional AI adoption, the lion’s share of that value does not come from reduced headcount or productivity gains. While those are factors, the real value CoCounsel Legal delivers is the ability to take on a greater number of matters concurrently by reducing the time required for research, document review, and matter ramp-up. As a result, the composite organization increased attorney matter capacity by 25% without adding headcount, allowing the firm to accept additional work from existing clients and pursue new matters.
• Productivity gains within core legal workflows: $1.7M
  Productivity, of course, is improved with AI, but the interesting finding in the Forrester analysis is that those productivity gains are concentrated in specific law firm workflows. Based on the analysis, attorneys spend less time on repetitive, low-value tasks such as document review, legal research, and drafting, which means CoCounsel is reducing nonbillable time and lowering write-downs on existing matters.

In addition to the quantitative benefits, the research also found several qualitative examples where incorporating CoCounsel into day-to-day tasks helped to improve both the quality of work and quality of life for the firms’ attorneys, such as the following:

• Improved quality and consistency of legal work product
  Attorneys reported that AI-generated summaries, research, and drafts are more reliable and thorough than traditional manual approaches, boosting confidence in the work product, cutting down on partner oversight, and reducing the chance that critical facts or arguments slip through the cracks.
• Greater focus on high-value legal judgment and client strategy
  By reducing time spent searching for information and compiling relevant case law, CoCounsel Legal allows attorneys to devote more effort to strategic analysis, advocacy, and client advisory work, enhancing perceived client value.
• Improved attorney experience and reduced burnout
  The fact that CoCounsel Legal allows attorneys to complete lower-value, repetitive tasks more quickly, while freeing up time to focus on more strategic work, improves day-to-day attorney experience and work-life balance, particularly for junior attorneys handling document-heavy matters.

Reclaiming the Work That Matters in Law

While the intent of the analysis was to deliver a definitive, by-the-numbers calculation of what kind of financial return law firms can expect from their investments in AI, the results revealed much more detail about the role AI is already playing in law firms, today. Importantly, it shines a spotlight on the fact that AI is having an accretive effect on the firms that have embraced it. Put simply, it is helping firms do more work better, ultimately helping them create more capacity and new opportunities for growth.

That’s a fundamental shift from the mainstream narrative on AI, which has often been cast as a productivity and cost-reduction tool. That’s really only a small part of the story. When the right AI tools are deployed effectively, they are removing points of friction and helping attorneys reclaim the work that matters. Importantly, they are also creating significant new growth channels along the way.

Introducing��CoCounsel��Legal Canada��

​​CoCounsel��Legal Canada is the only comprehensive AI solution for Canadian legal professionals that combines advanced AI capabilities with the authoritative depth of Westlaw content and the applied guidance of Practical Law, in a single integrated solution built for the way legal professionals work. Where other tools address parts of the legal workflow,��CoCounsel��Legal Canada is built to handle the full span of it. The result is faster, more��confident��legal work across research, document analysis, drafting, and organizational��know-how.​��

Here is what that looks like in practice:��

• Research that produces work��product.��Canadian legal professionals have had access to Deep Research on Westlaw Advantage, grounded in authoritative Westlaw content. CoCounsel Legal Canada takes that further. Through CoCounsel Legal Canada, Westlaw and Practical Law now are combined into a single query and response, surfacing answers for the user from both premium content sources. Westlaw’s legal authority and Practical Law’s applied, expert-created guidance surfaces the law and how to use it, moving from question to strategy to execution in a single workflow.�� ��
• Document analysis at��genuine��scale.��Tabular analysis allows legal teams to work through large volumes of documents in ways that weren’t previously feasible without significant resource commitment. Whether the task is due diligence, disclosure review, compliance assessment, or privilege review, CoCounsel Legal Canada surfaces risks across multiple issues simultaneously, links findings to source documents, and generates draft reports. The results are designed to be reviewed and challenged, because that is how legal work functions.��
• Drafting within existing environments.��Enhanced drafting within Microsoft Word allows lawyers to produce high-quality first drafts without leaving the tools they already use, drawing on Practical Law content and their own organizational precedents. The goal is not to replace professional judgment. It is to compress the distance between instruction and a verified, defensible final draft.��
• An expert library.��Access expert-created prompts and create custom prompts designed to help legal professionals get started faster and work with greater confidence. The library accelerates AI adoption across an organization while codifying best practices, so teams can build capability consistently rather than starting from scratch on every matter.��

​​​CoCounsel��Legal Canada integrates with Microsoft 365, leading document management systems, and HighQ, working within the infrastructure Canadian legal practices have already built rather than requiring parallel workflows or new platforms.��​​��

​​​Because the work of legal professionals doesn’t stand still, neither does CoCounsel Legal Canada. Looking further ahead, �������� will continue to build on its foundation, introducing additional agentic drafting capabilities, ways to enable more efficient lawyer verification of outputs, and next-gen capabilities that respond to a plain-language question by forming a theory and executing a plan at the level of a senior associate, drawing on Westlaw, Practical Law, and firm content throughout the workflow.​​��

“Lawyers don’t want to just operate software, and that’s not what��great��AI should do.��CoCounsel��keeps them in the analytical mindset they were trained for: going back and forth, challenging answers, and steering the work. With sourcing directly from Westlaw and Practical Law,��they’re��not wasting time second-guessing the results.��We’re��seeing adoption from associates to partners across every practice area. When it spreads that quickly, the experience just works.”
— Andrew M. Medeiros, Managing Director of Innovation, Troutman Pepper Locke LLP��

CoCounsel��Legal Canada is built to the standard legal work demands��

Powerful capabilities matter only if professionals can trust the results they produce. Legal work carries liability. Outputs inform advice. Advice affects outcomes. In that environment, “almost right” is not a workable standard.��

​​�������� uses the term Fiduciary-Grade AI��to describe what AI must be��in order to��function reliably in high-stakes professional environments, and it is the architectural foundation of��CoCounsel��Legal Canada.��​��

​​​​It means outputs grounded in authoritative, curated content, not the open internet. It means privacy and security built into the system’s architecture, not layered on as policy. It means transparent, traceable reasoning that a lawyer, client, court, or regulator can examine and challenge. And it means the continuous involvement of credentialed subject-matter experts. �������� employs thousands of lawyer editors whose work is not incidental to the product’s reliability. It is the product’s reliability.​​​��

“The reality is from what��we’re��seeing out��there,��it’s��not a fair fight right now.��CoCounsel��nailed it in terms of the user interface and making it easy for even non-technical people like me to use.”
— Ian Hull, Co-Founding Partner, Hull & Hull LLP��

The practices built today define the profession tomorrow��

The decisions being made now (the tools adopted, the workflows built, the institutional knowledge developed around how to deploy AI effectively) are the foundations of what Canadian legal practice looks like on the other side of this transition. Getting there successfully means choosing AI built for professional work, not just productivity, and investing in the workflow integration that turns capability into��a competitive��advantage.��

Canada has something valuable to contribute to the global conversation about what responsible AI adoption in regulated professions should look like. A professional culture built on precision, accountability, and trust is not an obstacle to AI adoption. It is the foundation for doing it right. The legal profession has always been defined by the trust placed in it. The practices that move deliberately now will be the ones defining what excellent Canadian legal work looks like in the years ahead.��

CoCounsel��Legal Canada is available now, and��we’re��proud to bring it to the professionals who set that standard.��

Ready to see��CoCounsel��Legal Canada in action?��.��

Today, we’re announcing the next generation of CoCounsel Legal, now available in Beta. Built from the ground up, it delivers on the vision we set out from the start: an AI companion that works alongside lawyers through every task and every stage of a matter, grounded in the trusted sources of knowledge they rely on.

Built on the most advanced AI, and engineered for how legal work actually gets done

Built on Anthropic’s Claude Agent SDK, the next generation of CoCounsel Legal is a unified agentic platform that plans, selects tools, retrieves authoritative content, and adapts mid-workflow just as a senior associate would, not a first-year waiting for the next instruction. Critically, the lawyer remains in control—able to see the agent’s reasoning as it unfolds, step in to redirect its approach, challenge its assumptions, and probe whether alternative angles have been considered.

CoCounsel Legal doesn’t reason from the web – it’s built with Westlaw and Practical Law content and tools natively embedded. Different by design, the technology and the sources are built as one system, making defensibility part of the architecture rather than a feature. As a result, when CoCounsel Legal produces a deal term sheet, contract, or litigation strategy memo, every step of its reasoning is grounded in authoritative legal sources, guided by 35 million West Key Number classifications and 3.9 million Precision Research attributes, and fully transparent through verifiable Practical Law resources and Westlaw citations. Developed and evaluated by practicing-attorney editors working alongside top AI data scientists, the breakthrough isn’t simply faster task completion – it’s the ability to produce complex work product across the many decision points of a legal matter, moving beyond task execution to true legal reasoning.

Our leading evaluation framework encodes quality at each step. This means before any capability ships; we measure it. Licensed attorneys, including our Practical Law editors, define what the correct output looks like for each task type. Every new capability must demonstrate measurable improvement against that benchmark before it reaches production. The framework evaluates not just final outputs, but the full chain of reasoning that produced them, because an agent that arrives at the right answer through flawed reasoning cannot be trusted to do so consistently.

And we’ve gone further to protect the integrity of that reasoning, with patent-pending tools for citation integrity and output verification:

• Verification and grounding as system primitives. Authoritative retrieval, explicit source handling, and verifiable citation flows are product infrastructure -not post-processing or marketing language.
• Patent-pending link integrity.��Our patent pending citation ledger architecture tracks every source the agent brings into context and the specific passages it reads.

This is ; outputs grounded in authoritative content and customer context – making verification part of the system’s architecture rather than an afterthought. In a profession where a single missed citation can cost a client their case, defensibility isn’t a nice-to-have. It’s the whole point. In a profession where a single missed citation can cost a client their case, defensibility isn’t a nice-to-have. It’s the whole point.

What our customers are telling us

The feedback we’re hearing from customers reflects this.

Brooke Conkle, partner in Consumer Financial Services at Troutman Pepper Locke, asked CoCounsel Legal a broad question about recent TCPA developments across two circuits and the solution “immediately zeroed in on the precise ascertainability nuances” between them, the kind of careful parsing that typically requires significant time and research. Her conclusion: “The underlying legal analysis genuinely blew me away and made me rethink what is possible with AI in complex litigation work.”

That’s not the response of someone who found a faster tool. That’s the response of someone who found a different kind of tool.

Andrew Medeiros, managing director of Innovation at Troutman Pepper Locke, captures something I think is fundamental to why this matters: “Lawyers don’t want to just operate software, and that’s not what great AI should do.” What he’s seeing is that CoCounsel Legal keeps lawyers in the analytical mindset they were trained for, going back and forth, challenging answers and steering the work.

He added: “The next generation of CoCounsel Legal seems to be a total game changer as��we’ve��introduced it to litigation and transactional attorneys. It’s meeting them within their workflows, allowing them to ask plain language questions and then see the step-by-step approach that CoCounsel [Legal] takes to help them draft the document relying upon Westlaw Deep Research and the Practical Law guidance.”

The AI Knowledge Management Department at Morgan Lewis, shared, “We were really impressed with the enhancements to the CoCounsel Legal platform. In our evaluation, it demonstrated strong capabilities in supporting efficient document drafting and in addressing gaps in information, such as filing party details, with both speed and accuracy when prompted. The outputs were well-structured and immediately usable, and the overall workflow was intuitive and easy to navigate. Performance was consistently fast. We are really looking forward to what’s next!”

Why we’re launching this as a beta, and building in public

Just as important as what we’re building is how we’re introducing it to customers.

We are deliberately launching the next generation of CoCounsel Legal as a beta, with a clear commitment to building in public and in partnership with our customers. This beta includes leading law firms such as Troutman Pepper Locke, Morgan Lewis, Carlton Fields, and Caplin & Drysdale, as well as four large enterprise customers. As we move through successive beta waves ahead of general availability later this year, we’re putting the solution in the hands of real lawyers working on real matters – listening closely to where it earns confidence, where it doesn’t, and incorporating that feedback directly into how the product evolves.

We’re inviting customers to help shape what CoCounsel Legal becomes – an AI that works at the level of a senior associate, built with Anthropic with cutting edge technology, engineers for legal work with authority and verification at its core.

This reflects a core belief I hold: the solution itself should be the argument. The strongest validation won’t come from launch announcements or benchmarks alone, but from sustained use – when lawyers choose to rely on the product because it holds up under real professional accountability.

Today’s beta is just the beginning. I’m excited to put the next generation of CoCounsel Legal in the hands of more customers as the year progresses.

I encourage you to explore how it works.

Rooted in Your Knowledge

Draft an Agreement Based on Your Precedent & Practical Law Content

Draft agreements faster without starting from scratch as CoCounsel’s drafting agent enables U.S. users to generate a comprehensive first draft in minutes using a trusted precedent or a Practical Law Standard Document. Simply upload source material, add key details and requirements, and CoCounsel analyzes the template, applies its structure and style, and produces a tailored multi‑page draft aligned to the instructions provided. The result is a quicker path from blank page to a client-ready draft in a streamlined workflow with less manual assembly allowing users to spend more time reviewing, negotiating, and advising. Review and then export to Microsoft Word when ready.

My Clauses

Using the new My Clauses in CoCounsel (U.S.), transactional lawyers can build a personal, searchable library of preferred contract provisions saved from playbooks, draft and modify outputs, or added manually so the right language is always within reach. Find what is needed in seconds, tailor it to the specific matter, and reuse it instantly across new agreements. That means less time hunting through old files, fewer drafting interruptions, more consistency across matters, and faster turnaround from first draft to final.

Built for How You Work

Draft Editor

Draft Editor is an integrated editing environment available in the U.S., UK, Canada, and Australia that lets users refine AI-generated outputs directly in their browser – no need to export to Word or switch applications. Available across key skills including Review Documents, Draft, Summarize, and Timeline, simply click ‘open editor’ to start refining work. By enabling in-place editing, it keeps users focused on their work instead of managing workflow. The result: faster turnaround times, fewer interruptions, and a seamless path from AI assistance to polished work product.

Region Settings

Now available in the U.S., UK, Canada and Australia, lawyers can access a flexible, jurisdiction selection feature built directly into CoCounsel for Microsoft Word that enables seamless switching between region content and localization – regardless of regional subscription. Users also can access corresponding Westlaw and Practical Law content from existing subscriptions without purchasing separate regional entitlements or managing multiple logins. Additionally, an improved capability to switch between jurisdictions eliminates geographical limitations in the drafting workflow.

Citations Format Update

CoCounsel now delivers citations as endnotes (with hyperlinks) instead of footnotes in the U.S., UK, Canada and Australia – so your finished Word document reads cleanly from start to finish – a key preference often heard from customers. When exporting the output of any CoCounsel skill or workflow, citations appear at the end of the document, and each in-text citation links to the supporting source and back again. This creates less scrolling and fewer distractions while the work is reviewed, shared, and finalized, especially on longer drafts and research-heavy documents. The in-app experience stays the same; this update improves the readability of exported documents while keeping sources easy to verify.

Tabular Analysis

Tabular analysis is now available in Canadian French.�� Users can review up to 10,000 documents and 100 questions, viewing the results in a dynamic, filterable table format.�� This flexible capability enables users to add or remove files or questions mid-review, analyze results in a three-pane viewer, and run multiple tables simultaneously. The powerful solution significantly reduces document review time while enabling easy verification with clickable footnotes. This allows legal professionals to concentrate more on strategic, high-value tasks, and enhancing productivity while reducing valuable resource needs.
