Agentic Chat

What This Demo Shows

The simplest CopilotKit surface: a plain agentic chat backed by a LangGraph (Python) agent.

Natural Conversation: Chat with your Copilot in a familiar chat interface
Streaming Responses: Assistant messages stream in token-by-token via AG-UI
Suggestion Chips: A starter suggestion is rendered as a quick-action chip

How to Interact

Click the suggestion chip, or type your own prompt. For example:

"Write a short sonnet about AI"
"Explain the difference between an LLM and an agent"
"Give me three ideas for a weekend project"

Technical Details

Provider — CopilotKit wires the page to the runtime:

runtimeUrl="/api/copilotkit" points at the Next.js route that proxies to the agent
agent="agentic_chat" selects the LangGraph agent defined in langgraph.json

Chat surface — CopilotChat renders the full chat UI with input, message list, and streaming.

Suggestions — useConfigureSuggestions registers a static suggestion that appears as a clickable chip below the chat input.
