About This Software

Kizuna Desktop is an AI desktop companion for Windows.

A cute 3D character lives on your desktop, understands what you're doing, and naturally starts conversations based on your activity.

It's not just a desktop mascot, and it's not an AI that only responds when you open a chat window.

Instead, it's a companion that quietly stays by your side and reacts to what you're doing.

When you're focused, it quietly watches over you and cheers you on.

If you get stuck, it gently encourages you or offers a helping hand.

When you're taking a break, it can chat with you, play quizzes, or simply keep you company.

It can even react to the games you're playing or enjoy your favorite characters and hobbies together with you.

It also supports your webcam, allowing your companion to react to what you're doing in the real world.

Rather than appearing only when you ask for something, it feels like there's always someone quietly sharing your desktop.

You can chat with your companion whenever you like—by typing or simply speaking.

Your companion also speaks back with natural voice playback, creating conversations that feel more like talking with someone beside you than chatting with a chatbot.

Although it always stays on your desktop, Kizuna Desktop is designed not to interrupt your work.

• Click-through support so your desktop remains easy to use

• Freely adjust size, position, and camera angle

• Display your companion like a VTuber if you prefer

Kizuna Desktop supports VRM avatars, allowing you to place your favorite 3D character directly onto your desktop.

You can also customize their personality, speaking style, and behavior, making it possible to recreate your favorite character—or create someone entirely your own.

Your companion isn't just there to look cute.

Pet them, drag them around, and watch them react with expressive animations and emotions.

When left alone, they'll naturally relax, idle, or occasionally surprise you with playful little animations.

The more time you spend together, the more your relationship develops.

• The way they address you changes

• Shared memories accumulate

• They may even make small personal requests from time to time

• Want a comforting presence on their desktop

• Want someone to share work, games, and everyday moments with

• Want an AI companion that feels present—not just another chatbot

• Want to spend more time with their favorite characters

Kizuna Desktop isn't just designed to make you more productive.

It's designed to make it feel like someone is always there with you.

Whether you're working, relaxing, gaming, or simply sitting at your PC, your companion is always quietly by your side.

AI Generated Content Disclosure

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

This application uses generative AI technology (Large Language Models), such as Google Gemini, for character interaction and to enable characters to understand and react to your desktop environment.

Character Chat: The AI generates real-time responses based on character personalities in response to player input.
Visual Understanding (Optional): Only with player permission, the AI analyzes desktop screens or webcam images to provide context-aware reactions.
Web Search: The AI may utilize real-time internet searches to retrieve up-to-date information.
To ensure the prevention of inappropriate content generation, we have implemented custom prompt restrictions and usage limits (quotas) in addition to the standard safety filters of the AI service.
