Growth comes from time together

PetOS turns a desktop pet into a growing AI agent. It stays with you, talks when it should, stays quiet when you focus, and writes every moment into local memory.

  • By your side Always-on, transparent, and draggable. It wanders, pauses, and reacts like a real companion on your desk.
  • Grows with you Chats and memories are isolated per pet. The longer you stay together, the more it feels like yours.
  • Quiet when needed Focus mode, quiet hours, and adjustable chatter. During a pomodoro it keeps a lower profile.

A desktop pet system

Built around growth and companionship: presence, interaction, memory, and control of your own data.

Always a pet, growing with you

The desktop bubble is the only chat entry. It answers in character, so companionship comes from living together, not generic Q&A.

  • Always present

    Transparent and topmost, with drag and play. No blunt taskbar icon, just a small life on your desk.

  • Local growth memory

    Keys and memory stay on your machine by default. Networking is opt-in. PetOS does not provide model hosting.

  • Bring your own model

    Add an OpenAI-compatible Base URL, key, and model name to start chatting and growing together.

  • Choose your partner

    Start with a built-in companion, or import from Petdex or a local folder. Each pet has its own memory space.
