# AI Prompt Editor

> Build and refine your assistant’s system prompt with AI chat, templates, and diff review—no deep technical knowledge required.

The **system prompt** is where you give your assistant a clear role, rules, and tone. In Famulor, the **AI Prompt Editor** helps you do that by **chatting with AI** on the left while your prompt stays visible on the right—so you rarely need to edit raw markdown by hand.

<div style={{ position: "relative", paddingBottom: "56.25%", height: 0 }}>
  <iframe style={{ position: "absolute", top: 0, left: 0, width: "100%", height: "100%", border: 0 }} src="https://www.tella.tv/video/system-prompt-erstellen-prompt-editor-8nav/embed?b=0&title=0&a=1&loop=0&t=0&muted=0&wt=0&o=1" allowFullScreen allowTransparency />
</div>

## Open the editor

1. Edit an assistant and scroll to the **System prompt** area.
2. Click **Start AI Prompt Editor** (light blue button). A modal opens with the chat on the **left** and the prompt on the **right**.

You can also continue from an existing prompt or reset—same pattern as other editors.

## Start from a template or a blank script

When the editor opens you can:

* **Pick a template** — Browse niches (e.g. real estate, reminders, sales). Templates are starting points you refine in chat.
* **Start from a blank script** — If you prefer to build everything yourself.

Scroll the library until you find a fit, select it, and the prompt loads on the right.

## Improve the prompt in chat

Describe changes in plain language. Example from the walkthrough: *forward calls when a customer is genuinely interested in a specific property.*

* Press **Send**. The AI proposes concrete edits.
* You can integrate suggestions **without touching the right-hand editor** if you accept them from the review UI.

## Review, accept, or reject changes

Suggested edits appear as a **diff** on the left:

* You see **what is removed** and **what is added**.
* Use **Accept all** to apply everything at once, or go **line by line** and tick changes you want.
* The main prompt view shows the same additions and removals clearly before you save.

## After you finish

Your **system prompt** appears at the bottom of the flow when you are done. You can still edit it directly—the UI is meant to feel approachable so you can iterate quickly without advanced technical skills.

<Tip>
  For screenshots, variables, post-call schema, and the full UI tour, see **[AI Prompt Editor](/en/ai-assistants/ai-prompt-editor)**.\
  Compare with **[Flow Builder](/en/platform/flow-builder)** when you need strict branching instead of a single rich prompt.
