Westlaw has set the standard for legal research for generations. It is trusted, authoritative, and deeply embedded in how legal professionals find and validate the law. As workloads grow more complex and expectations continue to rise, faster turnaround, deeper analysis, and greater accuracy are now the norm. Many Westlaw users are realizing that research alone is no longer enough.
They are expected to deliver accurate, defensible outcomes while navigating staffing shortages, flat or shrinking budgets, increasing workloads, and direct public accountability. Whether responding to FOIA requests, preparing regulatory filings, or drafting materials subject to judicial or public review, the margin for error is narrow and the demand for transparency is high.
That is where CoCounsel Legal comes in.
CoCounsel Legal is not simply another research tool or a generic AI assistant. Built on the same trusted foundation as Westlaw, it extends those capabilities into analysis, synthesis, drafting, and verification. The result is a clearer path from information to decisions, delivered with greater efficiency and confidence.
The following seven differences explain what Westlaw users should know.

1. From finding the law to working with it
Westlaw excels at helping you find authoritative law—cases, statutes, regulations, and secondary sources—quickly and accurately. CoCounsel Legal builds on that strength by helping you work with what you find.
Instead of stopping at a list of sources, CoCounsel can:
- Synthesize arguments across multiple briefs or filings
- Extract issues, claims, defenses, and timelines from large document sets
- Summarize how authorities apply to a specific fact pattern
- Organize research into structured, decision-ready outputs
For government users, this often means moving beyond locating authority to completing mission critical work, such as analyzing regulations before drafting an agency memo, reviewing precedents in preparation for judicial opinions, or validating citations prior to filing documents that may face internal or public scrutiny.
2. Research tasks to end-to-end legal workflows
Westlaw is purpose-built for research excellence. CoCounsel Legal is designed for end-to-end legal work.
CoCounsel supports workflows such as:
- Reviewing and comparing opposing briefs side by side
- Identifying inconsistencies, omissions, or mischaracterizations
- Drafting outlines or first-pass sections for motions, orders, or rulings
- Checking procedural compliance against rules and requirements
Rather than jumping between tools, or doing everything manually, CoCounsel brings these steps into one integrated experience rooted in Westlaw. This is particularly valuable in complex matters such as regulatory compliance reviews or multi‑stage filings, where accuracy must be maintained across every step.
3. From reading documents to understanding records at scale
Most legal professionals are skilled readers. The challenge today isn’t ability, but rather it’s volume.
Westlaw gives you access to critical documents. CoCounsel Legal helps you understand large, complex records faster by:
- Analyzing multiple filings at the same time
- Pulling out key facts, arguments, and cited authorities
- Highlighting where parties agree or diverge
- Linking every insight back to its source for verification
This is especially impactful for lengthy motions, administrative records, or appellate filings where manual synthesis can consume hours or days.
4. Citation checking to citation intelligence
Westlaw’s KeyCite remains the gold standard for citation validation. CoCounsel Legal adds another layer: citation intelligence inside documents and workflows.
With CoCounsel, you can:
- Detect potential mischaracterizations of the law in briefs
- Spot quotations taken out of context
- Flag weak or outdated authorities
- Verify precedential status and treatment while you work
Instead of checking citations after the fact, CoCounsel helps ensure accuracy during analysis, strengthening the defensibility of filings, opinions, and regulatory interpretations.
5. Research interfaces to conversational legal AI
Westlaw’s powerful search tools, specifically WestSearch, Precision Research, Key Numbers, are unmatched for targeted research. CoCounsel Legal introduces a chat-based legal AI assistant, grounded entirely in trusted legal content.
You can ask CoCounsel questions like:
- “Summarize the key arguments from both sides on this issue.”
- “What authority supports the standard of review here?”
- “Create a neutral issue outline based on this record.”
Every response is linked back to source material, ensuring the transparency and auditability that legal work requires. This approach moves legal professionals away from query‑driven searches and toward conversational, task‑oriented legal assistance.
6. General legal research to role-specific experiences
Westlaw is intentionally broad as it serves attorneys across practice areas and roles.
CoCounsel Legal is increasingly tailored to how specific legal professionals work, including judges, clerks, court staff, and government attorneys. Features like curated prompt libraries and role-specific workflows surface the capabilities that matter most for each user—without requiring them to hunt for the right tool.
7. Productivity gains to decision confidence
Speed matters but not at the expense of accuracy.
Westlaw accelerates research. CoCounsel Legal aims to increase confidence in outcomes, helping legal professionals:
- Reduce the risk of errors in filings and analysis
- Make defensible, well-supported decisions
- Maintain transparency and provenance in AI-assisted work
- Focus time on judgment, not manual processing
The intention is to amplify the user’s expertise by shifting the focus from doing research faster to making stronger, more defensible decisions.
Why this matters for Westlaw users
CoCounsel Legal is not a replacement for Westlaw, nor is it a generic AI layer added on top of existing tools. It represents the next evolution of the trusted ecosystem that Westlaw users already rely on.
Legal professionals continue to work with the same authoritative content and the same commitment to accuracy and transparency, while gaining expanded capabilities that support legal work where it actually happens.
For professionals who already trust the Westlaw foundation, CoCounsel Legal demonstrates how much more is possible when that foundation is extended.
