Thomson Reuters Westlaw’s Artificial Intelligence (AI) tools dramatically improve legal research efficiency by reducing the time, manual effort, and risk associated with traditional legal research. Lawyers using Westlaw AI report cutting research time from an average of 17–28 hours to around 3–5.5 hours per matter, without sacrificing accuracy. Here’s how:

How Westlaw’s AI Tools Enhance Efficiency

Conversational, Plain-Language Search
- Generative AI like Westlaw Precision and CoCounsel allows attorneys to pose complex legal questions in natural language, instantly returning relevant, context-rich results with clear links to source documents.
- This removes the guesswork and learning curve from Boolean or keyword-heavy queries.
Instant Authority Validation and Gap Analysis
- Features like Quick Check and KeyCite Citator use AI to analyze briefs, contracts, or pleadings for missing, negative, or contrary authority—in seconds—saving hours of manual review and protecting against overlooked precedents.
- Automated authority validation means higher accuracy and stronger legal arguments.
Litigation and Predictive Analytics
- Westlaw’s AI analyzes past cases, judge behavior, and litigation outcomes, offering actionable predictions for case strategy. Lawyers can tailor arguments and case planning based on real-world data instead of hunches.
Automated Jurisdictional and Statutory Surveying
- Tools like AI Jurisdictional Surveys quickly build comprehensive legal overviews for specific regions or statutes—tasks that previously took hours or days.

Quantifying the AI Advantage

Research tasks are completed up to 6–80 times faster and document review times drop by 50–80% using Westlaw’s AI versus manual methods.
Westlaw’s Artificial Intelligence (AI) tools can free up an average of four billable hours per week per lawyer, improving firm profitability and client value.

Example: AI That Thinks Like a Legal Expert

A typical attorney can upload a draft brief to Quick Check, which instantly flags unaddressed legal issues and suggests relevant precedents. What previously took several hours now takes minutes, letting lawyers focus more on strategy and advocacy.

Advisory Note

While Thomson Reuters (TR) Westlaw’s AI delivers speed and strong first drafts, final review by a lawyer is always essential to confirm accuracy and avoid rare errors or “hallucinations” that can occur with generative AI.

In summary, Westlaw’s AI tools streamline the most tedious and error-prone parts of legal research, letting lawyers work faster, smarter, and with greater confidence—giving them a measurable edge in today’s legal market.
