# Flow Builder

> Structured conversation flows vs. the AI Prompt Editor—nodes for speak, prompt, actions, and end call; ideal for outbound and sales.

When editing an assistant, you choose between the **AI Prompt Editor** (large text prompt) and the **Flow Builder** (visual structure). The Flow Builder is built for **clear rules and branching**—especially **outbound** and **sales** calls—while a classic prompt-first setup often fits **receptionist**-style assistants.

## Prompt Editor vs. Flow Builder (quick guide)

|              | **AI Prompt Editor**                                    | **Flow Builder**                                               |
| ------------ | ------------------------------------------------------- | -------------------------------------------------------------- |
| **Best for** | Receptionists, general inbound helpers, linear dialogue | Outbound, sales scripts, objection handling, big branchy logic |
| **Shape**    | One (or few) consolidated prompts                       | Nodes and paths on a canvas                                    |

## Starting the Flow Builder

Open the assistant, then launch the Flow Builder (alongside the prompt editor). Pick a **template** or start **from scratch**—same idea as with templates for the text editor.

## Node types

Use **Add node** to insert:

* **Start** — Opening message: how the assistant greets the caller.
* **Speak** — Exact script for the model to read (options such as word-for-word delivery and phonetic number reading where available).
* **Prompt** — Flexible instructions (e.g. qualify interest, handle objections). You can add **result branches** (for example “interested” vs. “not interested”) and wire each path to the next step or to **end call**.
* **Action** — Triggers such as **booking** or **call forwarding** (and other automations, depending on your setup).
* **End call** — When to hang up (e.g. after a negative response).

## Side settings

In the panel you can adjust **identity**, **first message**, and **conversation type** (e.g. sales, applicant screening, product feedback, customer service). Set **language**, **personality** sliders (e.g. assertiveness, humor), **voicemail** text, **variables** (e.g. first name from a lead list), and **post-call webhooks** for summaries or downstream automation.

## Import / export

**Export** and **import** let you download a flow and reuse it in other assistants (copy into another assistant as needed).

<Warning>
  **Use one or the other:** You work with either the **AI Prompt Editor** or the **Flow Builder**. If you already built a full prompt and then switch on or save the Flow Builder flow, the **prompt-editor content can be replaced**—plan accordingly and export backups if needed.
</Warning>
