Installation

Open a terminal and run:

pip install chainlit
chainlit hello

If this opens the hello app in your browser, you're all set!

Development version

The latest in-development version can be installed straight from GitHub with:

pip install git+https://github.com/Chainlit/chainlit.git#subdirectory=backend/

(Requires Node and pnpm installed on the system.)

🚀 Quickstart

🐍 Pure Python

Create a new file demo.py with the following code:

import chainlit as cl


@cl.step(type="tool")
async def tool():
    # Fake tool
    await cl.sleep(2)
    return "Response from the tool!"


@cl.on_message  # this function will be called every time a user inputs a message in the UI
async def main(message: cl.Message):
    """
    This function is called every time a user inputs a message in the UI.
    It sends back an intermediate response from the tool, followed by the final answer.

    Args:
        message: The user's message.

    Returns:
        None.
    """


    # Call the tool
    tool_res = await tool()

    await cl.Message(content=tool_res).send()

Now run it!

chainlit run demo.py -w
