Add @pixie.app decorator to your main application function:

# my_chatbot.py
from pydantic_ai import Agent

import pixie

# You can implement your application using any major AI development framework
agent = Agent(
    name="Simple chatbot",
    instructions="You are a helpful assistant.",
    model="gpt-4o-mini",
)


@pixie.app
async def my_chatbot():
    """Chatbot application example."""
    yield "How can I help you today?"
    messages = []
    while True:
        user_msg = yield pixie.InputRequired(str)
        response = await agent.run(user_msg, message_history=messages)
        messages = response.all_messages()
        yield response.output

The app will appear here automatically in a few seconds.
