## 🚀 Quickstart

### 🐍 Pure Python

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

```python
import chainlit as cl


@cl.on_message  # this function will be called every time a user inputs a message in the UI
async def main(message: str):
    # this is an intermediate step
    await cl.Message(author="Tool 1", content=f"Response from tool1", indent=1).send()

    # send back the final answer
    await cl.Message(content=f"This is the final answer").send()
```

Now run it!

```
$ chainlit run demo.py -w
```
