Exa Deep Web Research Multi-Agent System

What was done

Exa built a multi-agent web research system using LangGraph and LangSmith that performs deep, structured internet research. The system coordinates multiple specialized agents: a planning agent breaks down research questions, search agents query the web in parallel using Exa's neural search API, and a synthesis agent combines findings into coherent reports. The architecture demonstrates production-grade agent orchestration for tasks that previously required hours of manual research.
