Aifu

Aifu is a 3D virtual companion designed to keep you company throughout your digital day. Unlike conventional, flat chatbots, Aifu is built to interact in a much more lifelike way: it can remember your conversations, grow alongside you through persistent memory, and recognize its own visual identity on screen.

Talk Naturally

Type a message or use voice dictation. Hear replies through native Windows speech synthesis or advanced voices, and choose the voice experience that suits you.

Identities and Persistent Memory

Create independent identities with their own personalities and conversation memories. Return to earlier topics across sessions, without sharing one identity’s memories with another. Each identity also knows what its avatar looks like and can talk about its own look and style.

Little Interactions

Give your companion a head pat and watch them react. Small gestures and animated expressions make everyday moments on your desktop a little more playful.

Make Yourself at Home

Click and drag your companion to a new spot on your desktop. Keep them close while you browse, study, or take a break.

Take a Play Break

Challenge Aifu to tic-tac-toe or chess, roll the dice, or leave a decision to a coin toss. Your companion reacts as you play, turning a short break into a shared moment.

Your Companion, Your Look

Import your own avatar, including VRM and unitypackage files, and make it feel at home on your screen. Depending on the model, you can customize different parts of its look. With any avatar, you can also adjust settings like the camera and lighting.

Free Daily Use

Enjoy up to 30 free messages every day to chat, connect, and spend time with Aifu.

A Little Help When You Need It

Share an image or screenshot for Aifu to discuss. Ask for an internet search, set a timer, or start a Pomodoro session in natural language. Optional desktop tools and integrations are used only when you enable them.

Agentic Capabilities and Vision

Aifu doesn’t just talk—it executes tasks to support your workflow:

• Active Assistance: Request real-time internet searches to resolve queries or manage timers and Pomodoro sessions using natural language.
• Vision Capabilities: Aifu can analyze what you see. Provide screenshots or paste images directly into the chat for your companion to process, analyze, and comment on.

By Fans, for Fans

We’re AifuStudio, a small independent team who love anime and technology. Aifu began as a companion we wanted on our own desktops. During Early Access, we’re improving the experience with feedback from the community.

Our Cost Philosophy

We want to be 100% transparent: our main goal is not to make a profit. In order for Aifu’s responses to be smart, fluid, and backed by real memory, we rely on infrastructure providers and external high-performance AI servers that charge us for every single interaction.

The application’s pricing model is strictly designed to make the project sustainable and viable over time, covering these direct technical costs. Every single coin collected is reinvested into keeping the servers running and funding the development of new features. Thank you for helping us bring this dream to life!
