# Personality

> Customize how Tandem writes and communicates with you.

## What is personality?

Tandem's personality setting controls how it writes — the tone, style, level of detail, and humor in its responses. By default, Tandem is warm and direct. You can customize this to match your preferences.

## Setting your personality

From **Settings → Personality** in the app, or from the CLI:

```bash theme={null}
# See your current setting
tandem personality show

# Set it in one command
tandem personality set "Be direct and terse. Skip pleasantries. Just tell me what I need to know."

# Edit interactively
tandem personality edit

# Clear back to Tandem's default
tandem personality clear
```

## Examples

**Formal and professional:**

```
Write formally. Use complete sentences and professional language. No contractions or slang.
```

**Casual and punchy:**

```
Be casual. Short sentences. Talk like a real person. No corporate-speak.
```

**Direct and minimal:**

```
Be extremely terse. No filler. State facts only. Skip all pleasantries and affirmations.
```

**With personality:**

```
Be warm and a little funny. Dry wit is welcome. Keep it practical but not boring.
```

## How it applies

Your personality setting applies to all AI interactions in Tandem — task planning conversations, the Today summary, and any AI-assisted updates. It does not affect the structured data in your tasks (titles, deadlines, subtasks).
