Generative AI is changing how legal teams research, draft, summarize, and review work—often with measurable efficiency gains. This page connects adoption and spend to outcomes like faster contract review, less time drafting, and lower manual effort, while also addressing adoption friction such as hallucinations and fairness concerns. Use the stats to see where generative AI is already being used and what risks and barriers still slow rollout.
