ZeroTwo lets you set the general voice of its answers in one place. The setting is called **Base style and tone**, and it changes how ZeroTwo sounds, not what it is able to do.

## Choose a base style and tone

1. Select your name at the bottom of the sidebar, then choose **Settings**.
2. Open **Personalization** and stay on the **Companion** tab.
3. Open the **Base style and tone** menu and pick a style. Each option shows a short description.

The iPhone, iPad and Android apps have a **Base style and tone** setting under Personalization as well. The iPhone and iPad apps list all nine styles. The Android app lists the same styles except **None**. The choice is stored with your account, so it follows you between the web app, the desktop app and mobile.

## The styles

| Style | Description in the menu |
| --- | --- |
| **None** | No specific style or tone |
| **Default** | Preset style and tone |
| **Professional** | Polished and precise |
| **Friendly** | Warm and chatty |
| **Candid** | Direct and encouraging |
| **Quirky** | Playful and imaginative |
| **Efficient** | Concise and plain |
| **Nerdy** | Exploratory and enthusiastic |
| **Cynical** | Critical and sarcastic |

If you want ZeroTwo to apply no particular voice, choose **None**. **Default** uses ZeroTwo's preset style and tone.

## Name your companion

Just above the style menu is **Companion's name**. Type a name there if you want to give ZeroTwo a name that feels more personal. The field suggests "ZeroTwo" as an example.

## Go beyond a preset

The nine styles are fixed presets. ZeroTwo does not offer separate sliders for traits such as warmth or enthusiasm. For finer control, use these settings on the same tab:

- **Custom instructions** for your own wording, such as "keep answers under five sentences". See [Setting custom instructions in ZeroTwo](https://help.zerotwo.ai/en/articles/8096356-setting-custom-instructions-in-zerotwo).
- **Writing style**, a switch that has ZeroTwo write in your voice by referencing examples from your connected apps. Turning it on opens its setup.
- **Remove static instructions**, which strips ZeroTwo's tool instructions and rules from the system prompt for a more natural, personalized chat.

Details about you, such as your preferred name and occupation, live on the **Profile** tab of the same page.
