AI SDK RSC is currently experimental. We recommend using [AI SDK
UI](/docs/ai-sdk-ui/overview) for production. For guidance on migrating from
RSC to UI, see our [migration guide](/docs/ai-sdk-rsc/migrating-to-ui).

It is a hook that enables you to read and update the UI State. The state is client-side and can contain functions, React nodes, and other data. UIState is the visual representation of the AI state.

## Import

## API Signature

### Returns

Similar to useState, it is an array, where the first element is the current UI state and the second element is the function that updates the state.
