# Behaviour

> Configure how the NBQ Engine approaches and phrases questions.

The **Behaviour** tab (labelled *Comportement* in the interface) has two free-text fields and a tone selector that shape how your agent operates.

Fill in your **Objective** and **Business expectations** in plain language, then pick a **Tone** preset. These settings tell the engine what it is trying to achieve and how to phrase each question at runtime.

## Configuration fields

| Field                     | Description                                                                                                  |
| ------------------------- | ------------------------------------------------------------------------------------------------------------ |
| **Objective**             | The goal of the agent in your own words — e.g. *"Qualify the visitor's need before recommending a product."* |
| **Business expectations** | What you expect the agent to achieve and the key information it should collect during a conversation.        |
| **Tone**                  | A single choice among presets that shapes how each question is phrased at runtime.                           |

## Tone presets

| Preset            | When to use                             |
| ----------------- | --------------------------------------- |
| **Neutral**       | General-purpose; no particular register |
| **Direct**        | Concise, no-frills phrasing             |
| **Professional**  | Formal business context                 |
| **Friendly**      | Warm, approachable phrasing             |
| **Premium**       | High-end or luxury context              |
| **Commercial**    | Sales-oriented language                 |
| **Institutional** | Government, healthcare, or official use |

<Tabs>
  <Tab title="LLM Enabled">
    NBQ automatically reformulates the question text in the selected tone and the visitor's detected language before returning it — the `text` field is ready to display as-is.
  </Tab>

  <Tab title="LLM Disabled">
    Questions are returned exactly as they were written in the NBQ Studio. No reformulation is applied, so the `text` field contains the raw wording you entered.
  </Tab>
