# Gateway: Outside Messages

The Gateway lets an extension bring messages from an outside channel — for example a website chat — into Cowork, and send the AI's reply back to that channel.

## When to use it

When messages from an outside channel, such as a website chat, should be answered by the AI in Cowork.

## How to use it

It is off by default. Only you can switch it on, in **Settings › Gateway**:

| Setting | What it does |
|---|---|
| Gateway switch, and one switch per channel | Turn message handling on or off. |
| **Kill** / **Kill all** | Stop everything at once. **Lift the kill** to resume. |
| **Persona and rules** | Who the AI is in this channel, and what it may and may not say. |
| **Model** | The model that answers this channel. |
| **File access** | Which folder the AI may read for this channel. |
| **Trial** | Show you each reply for confirmation before it is sent. |
| **Recent audit** | The last 200 records of what came in and went out. |

The Gateway needs an extension that provides the channel (see [Extensions](https://docs.micromeet.ai/connections/extensions.md)).
