SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of customizing a personal assistant’s look so the experience feels more like you, without needing manual design work or complex image tooling.

Core Features & Use Cases

  • Native character avatars: Choose a body shape, eye style, and color to render an animated character, with an auto-generated static image for other clients and UI.
  • Custom image avatars: Upload an image to use as a static avatar while preserving native character traits for later restoration.
  • AI-generated avatars: Generate a custom avatar from a text description and apply it as the assistant’s image.
  • Lifecycle management: Remove the current avatar and automatically restore the native character configuration when available, plus view the current avatar as an image or base64.

Quick Start

Ask to set your avatar by telling the assistant which mode you want (build a character, upload an image, or generate with AI) and what look to use.
