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.
- Fully local AI
- No cloud, no account
- She speaks ten languages
- One-time purchase
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.
All footage captured in-game.
A conversation, not a chatbot
- Talk or type
- Speak naturally and cut in while she is still talking, or type when you would rather stay quiet.
- She answers out loud
- A neural voice that can sound warm, playful, shy or sulky, matched sentence by sentence to the look on her face.
- She speaks ten languages
- 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.
- Fully local AI
- The model runs offline on your machine. Your conversations never leave it.
Presence you can feel
- She notices you
- A glance to the side, then her eyes find you, a small smile, and hello.
- She listens and thinks
- A tilt of the head while you type, a look away while she finds the words.
- She has a life between sentences
- She looks around, fixes her hair, shifts her weight and changes pose on her own.
- She speaks first
- Go quiet for a while and she asks what is on your mind. Step away and she welcomes you back.
- She moves when she talks
- Nods on the words that matter, raised brows, and gestures that fit what she is saying.
She sings. She even writes the songs.
- Songs of her own
- Ask for a song about anything and she writes the lyrics and the music herself, right on your PC, then performs it for you about five minutes later.
- Teach her your favourites
- Give her an audio file, or let her look in your music folder, and she learns the song and performs it with lip-sync and lyrics on screen.
- Dance
- Full-body dance routines, with hair and dresses that swing as she moves.
Three companions
Simei, Ayami and April each have their own face, voice and first language (Chinese, Japanese and Korean), and each of them will follow you into any language she speaks. Moonrise, a fourth companion, is waiting in the in-game store.

Now in the game
Give her a dance she has never seen
Paste a folder with the motion and the song into the chat. She learns it on your own PC, the song first and then the moves, and a few minutes later she dances it for you.

Private by design
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.
