Lexis® Argument Analyser
Achieve deep case law research powered by artificial intelligence and trusted LexisNexis® content in minutes

How long does it take you to feel certain that your legal research is complete?


Astute legal professionals know how case law can change in real time. How often have you read a case knowing there’s a related case out there, but you can’t remember the details? When do you know that you have done enough legal research to move forward?

Lexis Argument Analyser uses the power of artificial intelligence (AI) to enhance your case law research by swiftly unearthing deep insights in relation to your matter.

The final product may differ from what is shown in the video, and some features may not be available in the New Zealand version.

What if you could see deep case law research directly related to any matter in one intuitive dashboard?


Traditional legal research can involve a tremendous amount of hard work, often at short notice. Reviewing hundreds of documents, building a court bundle, responding to a brief, or sharing your findings with clients and colleagues can involve successive keyword searches and repetitive document downloads.

Lexis Argument Analyser can fast-track your work. Simply upload a legal document and Argument Analyser will comb through LexisNexis’ vast caselaw database to return curated case recommendations, downloadable authorities, citation analysis, and a map of the salient legal issues in your document.

These results are presented in one secure and dynamic dashboard, where you can cross-check risks and opportunities without relying solely on prior knowledge or experience. You may even analyse your opposing counsel’s submission and be better prepared to mitigate risks.

With the peace of mind that you haven’t overlooked anything, you’re ready to craft a persuasive argument.
