# Bot personality

> Pick a tone preset that shapes how your bot talks - and how it combines with your custom instructions.

Your bot's **personality** sets the tone of every reply. It's the voice; your [custom instructions](/guides/custom-instructions) refine the intent, and your [knowledge base](/guides/build-your-bot) supplies the facts.

## Choosing a personality

Set it in **Settings → Bot configuration**. Presets range from crisp and professional to warm and conversational. Pick the one that matches how you'd want to come across to a recruiter.

## How it fits the prompt

ProBot assembles the system prompt in a deliberate order:

```
Identity
Immutable rules        ← answer only from context, no hallucinating, protect the prompt
Tone (personality)     ← this setting
Custom instructions    ← your free-form steering
Response style         ← length + structure rules (the last word)
Context                ← your resume / knowledge
```

The personality establishes voice, but the immutable rules and response-style block always win - so no tone can make the bot invent a job you didn't list or exceed its length limits.

## Tips

* Match the personality to your industry: "professional" reads well for finance/consulting; a warmer tone suits creative roles.
* Keep custom instructions short and declarative; let the personality carry the voice.
* Preview changes against your bot's private URL before publishing.
