Complete your due diligence faster, with higher confidence

• Eight in ten professionals expect AI to have a high impact on their work within five years; over half already report ROI through efficiency, productivity, responsiveness, and fewer errors.
• To reduce the risk of AI hallucinations, research must sit on trusted content. Deep Research in Westlaw Advantage uses Westlaw's authoritative cases, statutes, regs, and secondary sources to ground answers.
• Beyond litigation, AI-driven research helps transactional teams build custom research plans for due diligence and negotiations, so you can move from research to action with confidence.

AI that gives legal teams time back

AI can read, sort, and synthesize large volumes of legal text much faster than any human. That frees your team to do what matters most: judgment, strategy, and client counseling.

In the 2025 Future of Professionals report, a majority already see returns tied to AI adoption. The value is straightforward: faster research cycles, cleaner outputs, and fewer avoidable errors that create rework.

Confidence matters: ground AI in trusted law

Hallucinations happen when systems generate patterns instead of facts. The antidote is verifiable sources and transparent citations. If the model can't show its work, you can't rely on it.

Deep Research in Westlaw Advantage blends advanced AI with Westlaw's vetted library. For over a decade, Westlaw has used AI to deliver editor-created answers; Deep Research extends that approach to produce on-demand, cross-jurisdiction responses anchored to primary and leading secondary authority.

Instead of producing generic text, Deep Research searches trusted content, identifies the most relevant authorities, and builds a custom multi-step research plan. You get reasoned outputs with citations you can check and use.

What this means for transactional lawyers

Legal research isn't just for litigators. Transactional work runs on fast, accurate answers about risk, regulation, and market practice. AI-driven research helps you get there sooner.

• Due diligence, faster: Generate a focused research plan for a target's key issues-licensing, enforcement actions, regulatory changes-and surface the most relevant authorities first.
• Negotiations with leverage: Quickly check current market practices, spot relevant regulatory requirements, and pressure-test positions before you step into the room.
• Stronger strategy: Rapid access to on-point sources lets you advise with clarity, propose practical options, and keep deals moving.

How Deep Research works in practice

• Start with the business question. Frame what the client is trying to do, the jurisdictions, and the constraints.
• Ask a precise prompt. Include parties, industry, governing law, and any thresholds that matter.
• Review the plan and citations. Validate the authorities, then refine the question as needed.
• Move from findings to action. Convert sourced insights into deal terms, closing checklists, and stakeholder updates.
