Artificial intelligence (AI) is rapidly reshaping the landscape of litigation, a field traditionally driven by procedural rigor, heavy documentation, and high-stakes courtroom strategy. According to the American Bar Association’s latest tech survey, 30% of law firms now use some form of AI tool, up from just 11% in 2023. Litigation attorneys are increasingly turning to AI to assist with tasks such as legal research, e-discovery, document review, trial preparation, and other related tasks. We’ve identified some of the most impactful AI tools that litigators are using to streamline workflows, reduce costs, and gain a competitive edge in the courtroom.
