# Simple vs Expert Mode

> Understand when to use Simple or Expert mode in the agent editor

The agent editor supports two interface modes. **Simple** keeps common setup paths visible. **Expert** adds advanced controls for model, voice, timing, tools, knowledge, campaigns, and exports.

**Switch modes:** Use the **Simple / Expert** toggle in the top right, or go to **Profile → Preferences**.

<Note>
  Switching modes never resets your configuration. Settings changed in Expert mode are preserved when you switch back to Simple.

* prompt variables
* prompt templates

* privacy basics
* conversation review
* agent testing entry points

## When To Use Each Mode

| Use Simple when...                                  | Use Expert when...                                                           |
| --------------------------------------------------- | ---------------------------------------------------------------------------- |
| You are building your first agent                   | You need custom model or voice providers                                     |
| Quick setup is more important than fine-tuning      | You are integrating MCP servers or custom APIs with variables                |
| You do not need dynamic pre-call context            | You need pre-call API lookups through Dynamic Context                        |
| Default turn-taking works well                      | You need precise control over timing, interruptions, or silence behavior     |
| You are a business user managing standard workflows | You are a developer, operations owner, or voice engineer optimizing behavior |

<Tip>
  Start in Simple mode. Switch to Expert when you need a control that is not shown. You can always switch back.
