Introduction

Westlaw Precision AI is Thomson Reuters' AI-powered research platform layered on top of Westlaw's case law database. Like Lexis+ AI, the product anchors generative answers in primary sources — every claim traces back to citations from the Westlaw corpus, mitigating the hallucinated-citation risk that has produced court sanctions for unwary lawyers.

Capabilities include: conversational legal research with source-linked answers, KeyCite citation validation, AI-assisted brief analysis, and integration with the broader Westlaw Edge ecosystem.

Best fit: US-focused firms already on Westlaw infrastructure, particularly litigation practices where source integrity is non-negotiable. The default research backbone for thousands of US law firms — making Westlaw Precision AI the path of least resistance for those teams.

Pricing is enterprise with custom quotes, bundled with Westlaw subscriptions.

Westlaw Precision AI and CoCounsel are siblings under Thomson Reuters. The former emphasizes research depth; the latter wraps research into broader drafting and workflow tasks. Many firms use both.
