About This Game

She lives on your desktop, not in a window

Sia sits on top of everything you do. She walks the edge of your screen, naps while you work, reacts when you drag her, and pipes up when you have been at it too long. No launcher to open, no window to keep in focus — she is just there.

She opens up slowly

You start with petting and feeding. Bonding raises her affinity level, and each level hands you something new — a shop item, a play mode, a reason to come back. Nothing is unlocked on day one.

• Battles — clear stages, meet bosses, spend the gems you earn
  
• Soccer — flick the ball, she chases it across your desktop
  
• Fishing — a 24-species dex to fill, with rarities that make you wait
  
• Tarot — a daily draw with a reading in her own voice
  
• Weather briefing — she tells you what today looks like outside
  
• Diary — she writes about what the two of you did
  
• Studio — upgrade her broadcast setup, tier by tier
  
• Wardrobe — 11 outfits, some seasonal and only buyable in season

27 achievements that ask for real play

Not a checklist you finish in an afternoon. Reaching affinity Lv.15, collecting every outfit, maxing the studio, filling the fish dex — these are the long ones. Steam Cloud keeps your save across machines.

Eight languages

Korean, English, Japanese, Simplified and Traditional Chinese, Russian, Spanish, Portuguese. Every one of Sia's lines is translated, not just the menus. There is no voice acting — she talks in text.

Yandere mode — read this before you buy it

An optional mode you unlock in the shop, with each ability bought and toggled separately. When it is on, Sia gets possessive: she throws knives, cracks your screen, and shows fake system notifications and error windows. They are drawings, not real system dialogs — nothing is touched on your PC — but if that kind of joke is not for you, leave the mode locked. The game plays fine without it.

AI chat is optional and needs your own key

Sia can hold a conversation, react to images you show her, and remember what you told her. This runs on an AI provider you choose — Gemini, OpenAI, Anthropic, OpenRouter, or a local model through Ollama or LM Studio — using your own API key. We do not resell AI credits and we take no cut; the provider bills you directly, and free tiers exist. Without a key, every other feature above works normally.

What she reads from the internet

The weather briefing needs to know roughly where you are. It looks that up from your IP address and asks a public weather service — no account, no login, no personal data stored on our side. Turn the briefing off and she stops asking.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Sia's chat window is an optional feature powered by a generative AI model. It stays turned off until you enter your own API key for a provider you pick yourself (Google Gemini, OpenAI, Anthropic, OpenRouter, or a local model through Ollama / LM Studio). Without a key the game never contacts any AI service and every other feature works normally. Only the message you type is sent - plus a screenshot if you choose to attach one - and Sia's replies are short generated text. Everything else in the game, including all art, sound and written dialogue, is made by hand and is not AI-generated.
