# Vision

> Understand what the vision tool does and when to use it in a scenario.

The vision tool captures a snapshot from the user's camera feed and adds that visual context to the LLM context during a live conversation.

Use it when your assistant needs access to the user's live video stream.

## Create a vision tool

### Attach via JSON

Add a function with `type: "vision"` and define a clear `name` and `description`.

The function name and description are shown to the LLM as tool metadata, so they should clearly describe when the tool should be called.

```json theme={null}
{
  "name": "<vision_tool_name>",
  "description": "<description>",
  "type": "vision"
}
```

For example:

```json theme={null}
{
  "name": "extract_insurance_card_details",
  "description": "Read the current camera frame and extract insurance card details such as payer name, member ID, and group number.",
  "type": "vision"
}
```

### Attach via UI

1. Open your scenario and go to the target node.
2. Click **Add function**.
3. In the modal, select the **Vision Tool** tab.
4. Enter a semantically meaningful function name and description.
