Use Deep Research

Deep Research uses agentic AI to analyze vast amounts of legal content, surface key precedents, and deliver clear, transparent insights - all in a fraction of the time traditional research requires. Spend less time sorting through results and more time building winning arguments, backed by comprehensive, accurate answers you can trust.
You can use Deep Research to streamline complex research.
  • Expert AI-powered research that moves you forward faster and more confidently.
  • Transparent and interactive with real time insights into how results are generated with step-by-step research notes.
  • Accessible insights and actionable output with a detailed, comprehensive report sharing valuable insights and arguments on both sides of the issue.

How it works

Deep Research employs an agentic process that mirrors the methodology of human researchers, utilizing Westlaw's proprietary tools to systematically analyze the trusted content available on Westlaw and Practical Law.
In addition, primary law is referenced in the responses with the actual language from the source, and links are included to read the full primary law documents. Deep Research reports also leverage state and federal administrative materials, secondary sources, and current awareness. Even with these and other precautions, Deep Research can occasionally produce inaccuracies, so it should always be used as part of a research process in connection with additional research to understand the nuance of the issues and further improve accuracy.
The AI-generated summary of results along with the list of primary law authority can be extraordinarily useful for getting an overview of the issues and pointers to primary and secondary authority, but it should never be used to advise a client, write a brief or motion for a court, or otherwise be relied on without doing further research.
note
Use Deep Research to accelerate your research, not to replace it.
