PetOS
An AI pet agent that grows with you
Always on your desk. It moves on its own, remembers your time together, and gets closer to you. Keys and memory stay on your device by default.
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.
