Agent Builder: A New Way to Build Custom Legal AI Agents
Harvey has announced Agent Builder, an evolution of its Workflow Builder that empowers legal teams to create custom agents tailored to their specific needs. The new tool allows teams to build agents that handle increasingly complex tasks while maintaining the precision and control required in legal work.
What Changed
Agent Builder replaces the previous Workflow Builder approach with a more sophisticated agentic system. Legal teams can now:
- Define custom agents that pull from different tools and adapt findings across multi-step processes
- Automate recurring tasks with consistent, reliable outputs tailored to firm-specific workflows
- Leverage improved AI models as the frontier continues to advance, enabling more sophisticated automation
Real-World Usage Today
Harvey's agentic capabilities are already deeply embedded in legal workflows:
- 400K+ agentic queries daily execute complex tasks like contract reviews and document editing
- 20M+ terms extracted through agents in review tables, streamlining document reviews across litigation and transactional matters
- 445K+ reports generated using Deep Analysis agents
- 25,000+ custom workflows already built by legal teams, with firms like GSK Stockmann using agents for accelerated due diligence and Ashurst creating practice-group-specific workflows that save hours on lease summaries
Why It Matters
As underlying AI models improve, Agent Builder enables legal teams to scale their expertise and unlock new levels of automation. Teams can now build increasingly sophisticated agents without requiring deep technical expertise, making enterprise-grade AI automation more accessible to legal organizations of all sizes.
