Research methodology: Check the cited research, model documentation and evaluation conditions before applying an AI technique to professional work.
Overview
AI legal research uses natural language processing and retrieval augmented generation to search, analyse, and synthesise legal information from case law, legislation, and regulatory materials. Unlike traditional keyword search, AI legal research understands the intent behind legal questions and delivers contextualised, cited analysis.
How AI Legal Research Works
Natural Language Query
The lawyer asks a legal question in plain English — no need for Boolean operators or keyword construction.
Semantic Retrieval
The AI searches a curated knowledge base of case law, legislation, and regulations using semantic similarity.
Contextual Analysis
Retrieved authorities are analysed in context, identifying relevant principles, holdings, and distinctions.
Cited Response
The system generates a structured response with citations to primary sources for verification.
