useAIState

As explained in Build AI-Enhanced Web Apps

useAIState is a Vercel AI SDK React hook that provides access to AI state defined in an AI context.

useAIState is a React hook from the Vercel AI SDK that reads AI state defined by a surrounding AI context. It lets child components access application-level AI data while useUIState handles UI data and useActions exposes configured server actions. section 4.2.2 section 4.2.3

The hook depends on an AI provider created with createAI and placed around the application layout. That provider defines initial AI state, initial UI state, and available actions, making the shared context available to descendant components. section 4.2.2

Reading AI state in a chat component

A client component can read the current AI state alongside UI conversation state and server actions: `const [conversation, setConversation] = useUIState(); const [aiState] = useAIState(); const { continueConversation } = useActions();`. The example keeps conversation messages in UI state while making AI state available for more complex conversation-aware behavior. section 4.2.3

How Build AI-Enhanced Web Apps covers it

How deep it goes
Defines the hook’s role and integration pattern, but defers its internal implementation and state-update mechanics.
Examples
Uses a chat page that reads AI state while updating conversation messages through UI state and invoking continueConversation.
What it assumes
Assumes React components and createAI context setup while distinguishing AI state from UI state.
What you can do after
Apply it to read shared AI state from a React component inside a createAI provider.
How it connects
Connects AI state with createAI, useUIState, useActions, server actions, and React context providers.
