What it does
Westlaw Precision AI is a legal research tool from Thomson Reuters aimed mainly at litigators. Lawyers use it to search case law, statutes, and regulations and to check whether a case is still good law with KeyCite. AI-Assisted Research answers plain-language questions and points to the source cases behind each answer, and a Litigation Document Analyzer scans a brief for weak citations or missing arguments. Thomson Reuters has recently marketed a broader tier called Westlaw Advantage that includes this AI research layer, so confirm current naming and features before buying. Small firms can buy Westlaw self-serve online; larger firms need a custom quote.
Where it can help
This fits a litigation team that lives inside case law every day. Solo attorneys and small firms can start with the self-serve online plan, which one legal-tech review lists near $257 to $400 a month per firm for up to 10 attorneys, as a planning figure only; firms above that size need a custom quote. A good pilot is one litigation team checking the AI research answers against their own case research for a few weeks. The main risk is accuracy, since independent legal-AI studies have found that tools in this category can still return wrong case citations, and this tool is no exception, so every AI-generated citation needs a human check before it goes into a filing.
