The AI use cases powering daily legal work | Harvey
How legal teams are using Harvey across top use cases identified in the Briefing AI Leaders Community Index.
The legal industry is no longer asking whether generative AI will transform daily work, but how quickly that transformation will take hold, and where it will deliver real value first.
Recent data from the Briefing AI Leaders Community Index, which surveys more than 70 senior leaders across leading UK law firms, paints a picture of a profession in transition. Adoption is clearly underway: 50% of firms have already deployed legal-specific AI tools, with use cases spanning the full lifecycle of legal work — from summarisation, data extraction, and large-scale document review to due diligence, research, drafting, and knowledge management.
