Light body · standby
Your home has 11 AIs.
None of them have ever met.
Arua Core, the Holographic Core — a desktop AI multi-agent orchestration hub whose interface is a POV holographic light body.
Rendered live · light body rotating
It is not a fan that turns its head and glows. It is the assembly hall for every AI in your home.
Crowdfunding launch spots are limited. We send one email on launch day and nothing else — no pestering, no resale.
Problem
We invited AI into our homes, then locked it in the cloud
-
01
Every device fights its own corner
Your lights can't talk to the air conditioner, the robot vacuum doesn't know you have gone to bed, and the door lock and the camera never speak. Each one alone looks clever. Put together, they are anything but.
-
02
Control keeps fragmenting
Eight brands, eight apps, eight sets of voice commands. You can remember every wake word, yet not one device actually knows what "I'm home" means.
-
03
AI has no presence
It answers you, but it is not beside you. Cut the connection and it goes blind; close the screen and it vanishes. What you own is not an assistant but a string of APIs.
The problem was never that AI is not clever enough. It is that AI has no place to be present.
Product
Give AI a face, a nervous system and a body
The light body is its face
A dot-matrix holographic orb suspended inside the acrylic dome. Standby is a cool blue sphere, listening is a focused point of light, thinking is a cloud of particles, speaking is a ring of sound waves, and when it orchestrates it unfolds a floor plan of your home in the air. You do not have to stare at a screen to check whether it is listening — you can tell from the corner of your eye.
Wi-Fi is its nervous system
It does not try to replace any device in your home. Through the A2A (Agent-to-Agent) protocol and MCP tool calls, it gets lighting, air conditioning, security and cleaning into position, then moves them together.
The acrylic dome is its body
The high-speed rotating module is fully enclosed in a high-transparency acrylic dome. You can touch it, set it on a desk, let the cat come close. Safety is not an added guard net; it is the structure itself.
Local + cloud is its brain
A locally deployed lightweight LLM handles basic conversation and offline interaction; cloud models are woken on demand only when complex reasoning is needed. Cleverness in the cloud, reliability at your side.
It does not fetch your slippers itself. It gets the whole home to fetch them.

Light language
Five light languages
The light body speaks in states, not notifications. You do not have to open any app, or ask it "are you there?"
-
Standby
A cool blue sphere, breathing slowly. It is there, but it does not ask for your attention.
On this page: the node the section bar has not reached yet; the colour of a resting state.
-
Listening
The orb draws in to a single focused point of light. It only listens; it does not answer.
On this page: when the input field takes focus, its border draws in to a line of light.
-
Thinking
The cloud of particles spreads out and re-arranges. It is computing, and you can see the progress.
On this page: the uncertain state after the form is submitted.
-
Speaking
A ring of sound waves spreads from the centre. It is answering you.
On this page: the warm-coloured cue when success and error messages appear.
-
Orchestrating
It unfolds a floor plan of your home in the air and connects the devices that need to move into a single diagram.
On this page: the section bar links the seven chapters into one route.
Specs
Specifications
| Light body | POV holographic orb, visible glasses-free at 360°; five light languages — standby / listening / thinking / speaking / orchestrating |
|---|---|
| Sensing | Wide-angle camera × 1, 4-microphone array, mmWave radar (senses presence and gestures, no imaging)
|
| Local brain | A locally deployed lightweight LLM (such as Qwen3-4B): basic conversation, offline interaction |
| Cloud brain | Cloud LLMs woken on demand (such as GPT-4o / Claude) to handle complex reasoning |
| Protocol | A2A (Agent-to-Agent) + MCP tool calls |
| Noise | 25dB (aluminium heat conduction + chimney-effect passive cooling, no fan) |
| Construction | ≥90% high-transparency acrylic dome (anti-reflective coating) + matte black anodised aluminium base |
Three sensors cover for one another: the microphones hear commands, the radar knows presence, the camera understands the scene. Take away any one of them and it is only half a housemate.

Proof
The physical presence of AI is already market-proven
| Product | Vendor positioning | Public crowdfunding result |
|---|---|---|
| Dipal D1 | Holographic AI pod | Over US$1.4M (early bird US$379) |
| Cubie | Localised AI companion | About US$1.03M (early bird US$199) |
| ClawStage | Transparent-screen AI physical body | Over US$610K (early bird US$179) |
| ropet | Desktop emotional companion | Nearly 20,000 units shipped, 80–90% 90-day retention |
The above is third-party public data, counted as of September 2026; "vendor positioning" is each brand's own wording, and technical descriptions and figures should be taken as published on their official pages and crowdfunding platforms.
The market has already proved one thing — people will pay for the physical presence of AI. But nobody has yet turned that presence into real orchestration capability.
Arua Core's price and early-bird price will be announced on the crowdfunding page. Those who register for Early Access will be notified first.
FAQ
FAQ
Does it still work when the internet is down?
Yes. A locally deployed lightweight LLM handles basic conversation and everyday commands, so it can keep talking with the connection down; cloud LLMs are woken on demand only when complex reasoning is needed. Cleverness in the cloud, reliability at your side.
Will it replace the smart devices I already have?
No. It does not try to replace any device; through the A2A (Agent-to-Agent) protocol and MCP tool calls it orchestrates lighting, air conditioning, security and cleaning together, so they work as one.
What about privacy? Does the camera record me?
Sensing works in three layers: the microphones hear commands, the mmWave radar senses only presence and gestures (no imaging), and the camera understands the scene. Everyday conversation is handled on the device first and is uploaded only when cloud reasoning is needed.
Is it noisy?
25dB. Aluminium heat conduction and chimney-effect passive cooling, with no fan. Quiet enough to be almost absent — until you need it.
There are fast-spinning parts inside the dome. Is it dangerous to touch?
The rotating module is fully enclosed inside the high-transparency acrylic dome. Safety is the structure itself, not an added guard net: you can touch it, it fits on a desk, and the cat coming close is no problem.
Which devices and platforms are supported?
Devices and services that support the A2A protocol and MCP tool calls, connected over Wi-Fi. The detailed compatibility list will be published on the crowdfunding page.
When can I buy it, and how do I join Early Access?
Arua Core is coming to crowdfunding. Leave your Email on this page and you will be the first to hear on launch day — we send only that one message, no pestering, no resale.
