AI Digital Human Lab

A Digital Human Who Listens, Understands, and Answers in Her Own Voice

Meet Luna, a lifelike digital human who lives right on your PC. Talk to her by voice or text — ask a question, share your day, tell a story — and she answers in the moment, in her own voice, with accurate lip-sync, 74 facial expressions and gestures that fit what she says. No scripts, no dialogue trees: every reply is generated live. Her language model and her voice run on your own graphics card, so your conversations stay on your PC — no subscription, no API keys.

Optional: Connect an AI Assistant (MCP)

AI Digital Human Lab has a built-in MCP server (Model Context Protocol, the open standard AI assistants use to work with apps). If you use an AI assistant that supports MCP, you can connect it, and it can see the scene and direct it: speak through her, set the lights and the camera, dress her, pose her, start a dance, and capture the moment. This is entirely optional: the game is complete without it, and you need nothing outside Steam to play.

• Connect in seconds — click the robot button in the chat bar (or type /mcp bind), scan the QR code with your phone, and send one message to your agent. No API keys, no configuration files.

• Your agent speaks as her — hand the conversation to your agent: your words go to it, and she answers with its words, lip-synced and with matching expressions. Switch back to her built-in AI anytime.

• A director at your command — more than 40 tools: camera angles, studio lighting, the look of the picture, poses, motions, outfits, hairstyles, backdrops, face sculpting, and her voice, all just by asking.

• She remembers you — your agent can tell her your name, what you like, and what is going on in your life, and she keeps it in mind in her own conversations too.

• Photos, video, and live streams — ask for a picture, record a clip, or go live on YouTube; your agent can look at the screen to check the result.

• On your PC or from the cloud — local agents connect right on this PC; cloud-based assistants reach your game through our secure relay. The game connects out, so nothing on your PC is opened to the internet.

• You stay in control — one command issues a new key and locks out every agent using the old one, and the relay only passes messages through: it does not keep your conversations.

Key Features

• Real-time AI conversation — open-ended dialogue by voice or text, answered aloud sentence by sentence

• A performance that feels alive — 74 facial expressions, accurate lip-sync, and gestures chosen for each sentence; when you are quiet, she still moves, glances, and breathes

• 10 voice languages, 31 interface languages — she speaks English, Chinese, Japanese, Korean, German, French, Spanish, Italian, Portuguese, and Russian; the interface follows your system language, with optional dual subtitles in your native language

• Voices — nine built-in on-device voices, or voices you clone on your own PC

• Face sculpting — detailed sliders, control points, and presets, plus skin tone and makeup; or let your agent shape her face from a portrait

• Dance, pose, and move — a motion library of dances and idle moves, pose presets, and free posing; she can even learn a new dance from an MMD motion file and its song

• Webcam mirror — your webcam drives her face and body in real time

• Songs written for you — give her a theme and she writes and sings an original song with karaoke lyrics, or learns a song from your own music file

• Studio camera and lighting — orbit freely, frame shots with camera presets, switch lighting moods, take photos, and record video in-game

• High-fidelity digital humans — built with Unreal Engine 5: detailed skin, eyes, and simulated hair rendered in real time

You Choose Her Mind

Her intelligence is yours to configure. Run the built-in model directly on your PC — fully offline, completely private, with no subscription and no API keys required. Or, if you like, let an AI assistant that supports MCP take over. Switch whenever you like — and as models and updates improve, so does she: smarter, more natural, more alive.

Make Her Truly Yours

Choose Luna or Orion, change outfits and hairstyles, sculpt every feature of the face, give them the voice you like, and set the backdrop and the light — then watch the personality come through in every glance and gesture. Frame the perfect shot with the free camera and keep it as a photo or a video.

Made for creators, storytellers, AI tinkerers, and anyone curious about what it feels like when AI truly responds.
