An AI legal assistant is software that uses artificial • Understands natural-language questions
intelligence, especially large language models (LLMs), 
to help legal professionals research, draft, summarise • Retrieves relevant law, cases and documents
and analyse legal material using plain-language • Generates summaries, drafts and answers
instructions. • Works alongside, never instead of, the lawyer
Think of it as a fast, tireless junior colleague: it • Best versions cite their sources
prepares a first pass, and the lawyer reviews, verifies 
and decides.
Key idea: AI accelerates the work; the lawyer stays accountable for the result.

chatbots

terms
