Shared State

What is shared state?

Agentic Copilots maintain a shared state that seamlessly connects your UI with the agent's execution. This shared state system allows you to:

  • Display the agent's current progress and intermediate results
  • Update the agent's state through UI interactions
  • React to state changes in real-time across your application

When should I use this?

Use shared state when you want to facilitate collaboration between your agent and the user. Updates flow both ways — the agent's outputs are automatically reflected in the UI, and any inputs the user updates in the UI are automatically reflected in the agent's execution.
