AI Desktop Pet

AI desktop pet × local "tavern"-style roleplay × visual novel experience

She can be a character on your desktop that blinks and responds to your clicks;
an AI companion that talks to you with the voice you choose;
or a local "tavern" that loads your persona cards and writes a story together with you.
She can see your screen, and she may strike up a conversation while you are idle.
All core features run on your own device — no API keys, no internet required; and when you want a stronger model, you can connect your own cloud accounts at any time.

A desktop pet in many forms

• Supports VRM (3D), Spine (2D skeletal animation), static images (with day / night themes), Shimeji desktop mascots and more
• Ships with the original character "Coco" in three forms — VRM, Spine and static image — plus several built-in sample models
• Frameless transparent window, the model silhouette is the click area, with expression and motion interactions
• Every pet type can be subscribed and shared via Steam Workshop

A full-featured local "tavern"-style AI roleplay

• Built-in local large language model: no API key, no token purchases, no internet
• Import your own GGUF models (Llama / Qwen / Mistral / Gemma and more) and run them locally
• Multiple model sizes, with adjustable GPU offload and context length — runs on modest hardware too
• Optional cloud chat: connect around 30 cloud AI services with your own accounts, and switch freely between local and cloud
• Broad compatibility with mainstream persona-card formats; the characters you already collect just load
• World books, branching dialogue, long-term memory and a complete RP experience
• Full creation tools: built-in editors for persona cards and world books — create characters from scratch, or reshape any card as you like
• Export cards as PNG with an embedded world book to share with others, or publish to Steam Workshop in one click
• 100+ hand-crafted persona cards built in, with rich, varied stories ready to explore out of the box
• Persona cards and world books are also one-click shareable and subscribable on Steam Workshop

Voice chat and voice cloning

• Multilingual real-time speech recognition: built-in SenseVoice (CN / EN / JA / KO and more) and Parakeet (25 European languages with automatic language detection), with wake-word and continuous-conversation modes
• Multi-engine local speech synthesis with hundreds of built-in multilingual voices — or use the Windows system voices at almost no resource cost
• Voice cloning: give the character the voice you want from a short reference clip
• Optional cloud voice: 16 cloud TTS providers with your own accounts, including voices you have cloned on the provider's site

Vision and proactive dialogue

• The pet can look at your screen or a chosen window and describe or comment on what is happening
• It can start conversations while you are idle — trigger mode, frequency and quiet hours are all configurable
• Game companion: activate a game window and the pet chats along based on what is on screen

Steam Workshop

• Browse community creations and use them right away

Privacy and offline use

• Conversations are never uploaded to any server; cloud service keys are stored encrypted on your device
