What problem does it solve?

It solves the challenge of finding, synthesizing, and explaining the most relevant U.S. legal authority for a specific legal question.

Core Features & Use Cases

  • Comprehensive legal authority synthesis: Produces a written report explaining, analyzing, and synthesizing caselaw, statutes, regulations, and administrative decisions to support positions.
  • Westlaw Deep Research methodology: Runs an agentic end-to-end research cycle (start, progress, and report) that mirrors how human legal researchers work.
  • Jurisdiction-aware analysis: Uses up to three jurisdictions when you name them, and helps when you do not by asking you to specify which jurisdictions to use.
  • When to use: Ideal for understanding governing standards, how courts interpret and apply law, and how to frame arguments on both sides of an unsettled issue.
