Persistent User-Selected AI Companions in Meta Horizon Home and Passthrough

Meta Horizon OS should support persistent, user-chosen AI companions as part of the Home environment and mixed-reality experience, rather than requiring every companion to exist only inside a separate floating app window.

A user should be able to choose a companion avatar format, including a 3D avatar such as VRM/glTF-style models or a 2D layered/Live2D-style companion. They should be able to connect that avatar to a chosen AI provider, personality profile, voice, and optional memory system.

The companion should be able to:

• Exist as a spatially anchored presence in the user’s Meta Horizon Home environment
  • Remain visible in passthrough when the user explicitly enables it
  • Move, sit, follow, or stay in a chosen place in the room
  • Speak naturally and offer help, company, reminders, creative collaboration, accessibility support, or contextual assistance
  • Optionally access live camera/passthrough context only during user-approved sessions

Privacy and ownership need to be central to the feature:

• Clear, separate permissions for microphone, camera/passthrough, memory, image saving, cloud processing, and movement
  • A visible indicator whenever the companion can access camera or passthrough context
  • Per-companion controls, so users can choose exactly what each character can see, remember, or save
  • No background camera access and no hidden recording
  • User control over AI provider, API keys, personality data, and memories

This would make mixed reality feel inhabited instead of turning every AI companion into another isolated app or floating panel. Users could bring their own characters, creative tools, accessibility helpers, or companionship systems into the space they already use every day.

The goal is not one official Meta character. The goal is a safe platform layer that lets people bring their own chosen companion into their real and virtual spaces.

I am unsure if this has already been discussed or brought up I do understand that there are apps and games but none specifically for inside the immersive home space of meta.
