Please give me list of all business/industry sectors that may benefit from having a customer-facing internet chatbot agent helper.
Imagine that the chatbot will have a set of executable tools that interface with a system to help the customer's needs.


Please format your response as a JSON such as:
```json
[
    {
        "name": <name of item>,
        "applications": [
            {
                "function": <name of functionality the chatbot can have that can help the user>
            },
            ...
        ]
    },
    ...
]
```
