AI Contract Review: Automating Legal Document Analysis

Contract review is a cornerstone of legal practice but notoriously time-consuming. Lawyers spend countless hours poring over documents, identifying risks, and ensuring compliance. Artificial intelligence is transforming this process, enabling faster, more thorough contract analysis while freeing lawyers to focus on strategic advice rather than document drudgery.
