How It Works

1. Configure: Set up your agents by defining inputs/outputs, attaching RAG documents, connecting external APIs, and adding tools
2. Sketch: Arrange and connect multiple agents and tools on the canvas to build complex workflows visually
3. Integrate: Link agents with your own codebase so your functions become part of the workflow
4. Run: Execute the workflow directly and watch your agents collaborate in real time
5. Refine: Adjust agents, connections, or prompts iteratively to optimize performance
