# The Advanced Builder

> Every setting, grouped into sections, with one save bar, version history and an advisor.

The Advanced builder replaces the long form. Settings live in sections down the left, you open one
at a time, and a bar at the bottom keeps track of everything you changed.

## The sections

The sidebar groups the eleven sections by what you are doing: setting the assistant up, giving it
capabilities, then tuning it once it runs.

### Setup

| Section            | What it decides                                                                                  |
| ------------------ | ------------------------------------------------------------------------------------------------ |
| **General**        | Whether it makes or receives calls, its name, its number, and the engine it runs on              |
| **Voice & speech** | The language, the voice, how that voice delivers each line, background ambience and filler audio |
| **Brain & prompt** | The model it thinks with, and the system prompt it follows                                       |
| **Greeting**       | Who speaks first, and the first line the customer hears                                          |

### Capabilities

| Section                 | What it decides                                                                                                                     |
| ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------- |
| **Knowledgebase**       | The documents and pages it can answer from, and how it looks things up                                                              |
| **Tools & actions**     | What it can do mid-call: transfer, end the call, book, press or collect keypad digits, call your own endpoints, reach an MCP server |
| **Variables**           | What goes into the call, such as a customer name, and what is pulled out of it afterwards                                           |
| **Webhooks & channels** | Where the results are sent when a call or chat ends                                                                                 |
| **Web widget**          | The voice and chat widget you embed on your site                                                                                    |

### Tuning & insight

| Section           | What it decides                                                                  |
| ----------------- | -------------------------------------------------------------------------------- |
| **Call behavior** | Turn taking, how long calls and silences may run, recording and audio processing |
| **Activity**      | Recent calls for this assistant and how it has been doing                        |

## Finding one setting

Use **Search all settings** at the top of the sidebar. Type what you are after and the builder opens
the right section and scrolls to that field. If nothing matches, it says so rather than guessing.

The **Only sections I changed** switch at the bottom of the sidebar filters the list down to what
you touched in this sitting.

## Saving

Nothing saves as you type. The bar at the bottom shows **1 unsaved change** or **N unsaved changes**
and gives you three buttons.

| Button             | What it does                                           |
| ------------------ | ------------------------------------------------------ |
| **Review**         | Lists every change you made, with a link to each field |
| **Discard**        | Undoes every unsaved edit, in all sections             |
| **Save assistant** | Saves the whole assistant, all sections at once        |

The web widget is part of this too: changing it counts toward the unsaved total and is stored by the
same **Save assistant**.

<Warning>
  Tests run against the saved assistant. If you changed the prompt and want to hear it, save first —
  the test panel tells you when you have unsaved changes and offers a **Save** button.
</Warning>

## When something needs attention

Two different things can appear, and they mean different things.

* A red **Needs attention** strip inside a section lists settings that cannot be saved as they are,
  each with a **Jump to field** link. Saving is blocked until you fix them.
* The advisor banner — *N settings could be improved* — is advice, not a blocker. See
  [AI Advisor](/ai-assistants/ai-advisor).

## History

Every save that changes something becomes a version, and you can put any single line back without
touching the rest. See [Version history](/ai-assistants/version-history).

## Testing

**Test assistant** in the header opens the test panel: call your own phone, talk to the assistant
through your computer, or use the free text chat. See
[Testing your assistant](/ai-assistants/testing).

## Creating an assistant here

The **Advanced form** walks the same sections with **Next step** and **Go back**, and finishes with
**Create assistant**. The web widget is set up afterwards, once the assistant exists.
