AI Digital Human Studio
A lifelike AI companion who lives on your PC.
Talk by voice or text and she answers out loud with real expressions and gestures. She notices you, listens, and speaks first when you go quiet. Fully local AI: no cloud, no account. Shape her face, voice and style until she is yours.
She is not waiting for a prompt. She is waiting for you.
AI Digital Human Studio puts a lifelike digital human on your screen: one who looks up when you arrive, listens while you talk, thinks before she answers, and breaks the silence when you go quiet. Everything that makes her feel alive runs on your own PC: the language model, the speech recognition and her voice. No cloud. No account. No one else listening.
In-game captureA conversation, not a chatbot
A neural voice that can sound warm, playful, shy or sulky, matched sentence by sentence to the look on her face.

Go quiet for a while and she asks what is on your mind. Step away and she welcomes you back.

Give her a dance she has never seen

Frequently asked questions
- What is AI Digital Human Studio?
- AI Digital Human Studio puts a lifelike digital human on your screen: one who looks up when you arrive, listens while you talk, thinks before she answers, and breaks the silence when you go quiet. Everything that makes her feel alive runs on your own PC: the language model, the speech recognition and her voice. No cloud. No account. No one else listening.
- Does the AI really run on my own PC?
- Speech recognition, the language model and the voice all run locally. There is no login, and nothing you say is uploaded. A faster CPU and GPU make her quicker to answer and smoother to watch.
- Which languages does she speak?
- English, Chinese, Japanese, Korean, German, French, Spanish, Italian, Portuguese and Russian. Write to her in any of them and she follows; with a Windows voice she speaks many more. Voice input understands Chinese, English, Japanese, Korean and Cantonese out of the box, and every other language of the game with a free download from the in-game store.
- Is there a subscription?
- No. It is a one-time purchase on Steam. There is no subscription, and no API key to set up.
- What do I need to run it?
- A PC with Windows 10/11 (64-bit). The Steam page lists the full system requirements.
- Is it still being updated?
- AI Digital Human Studio is in active development. The local AI model, animation, wardrobe and performance improve with every update, and each one makes her a little smarter, more natural and more alive. Follow the Steam news feed to see what she learns next.
