# Character AI

This document outlines the process of adding a character, customizing its appearance and voice, and enabling it with artificial intelligence (AI) in GMetri.

**Steps:**

1. **Adding a Character:**
   * Follow the steps listed [Character](/metaverse/build/elements/character.md)
2. **Customizing Appearance and Voice:**
   * Adjust the character's scale, position, and rotation as needed.
   * If using a Ready Player Me avatar, access advanced customization through the "Edit in Ready Player Me" button.
   * Choose a voice from the available language options.
   * Adjust the voice pitch and talking speed
3. **Enabling AI:**
   * In the properties panel, select the checkbox "AI Brain"
   * Choose one of the available AI brain types:
     * **Q\&A Brain:** Ideal for answering questions based on provided knowledge sources.
     * **Roleplaying Brain:** Best for simulating characters in scripted scenarios.
     * **OpenAI Assistant (Enterprise Only)**
   * For Q\&A Brain:
     * Create a new brain by using the "Add brain" button.
     * Add context as required. 
     * Order matters, what you add first gets parsed first.
     * Upload or link to text files, PDFs, documents, or webpages relevant to the character's knowledge base.
     * Click the "Train" button to process the context and enable Q\&A functionality.
4. **Setting the AI Brain:**
   * In the right-hand toolbar, select the brain you just created from the sub-menu.

**Important Notes:**

* This feature is currently not supported on headsets.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.gmetri.com/metaverse/build/elements/character-ai.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
