A speaker. A phone. A.i.
Works online and offline. It sees, listens and projects.
The glass is the speaker.
01
Surface sound
Two exciters turn the glass into the speaker for mids and highs, and a racetrack woofer with a passive radiator moves the lows through the body. Three amplifiers, and it tunes itself to the room. No grilles.
2 exciters + woofer · 3 class-D amps
02
Bigger on its base
On its base it adds a 10 W woofer and a 5,000 mAh battery of its own: sound for a whole room, with no outlet.

Calls and messages, everywhere. No phone needed.
01
Your number, inside
An eSIM is the chip, already built in: your number, your calls and your messages, by voice. What you need to see, it projects.
eSIM · 5G
02
WhatsApp and your apps
Calls and messages over data with WhatsApp and the apps you already use, on Wi-Fi or 5G.
Calls over data
03
Where there is no signal
Text and emergency messages by satellite, and direct-to-cell calls as carriers switch them on with networks like SpaceX's.
Satellite (NTN)
04
It knows where you are
Dual-band GNSS with GPS, Galileo and BeiDou: precise location for maps and emergencies, also without internet.
GNSS L1 + L5
05
Hearing at a distance
Four beamforming MEMS microphones separate your voice from the noise, even on the street.

A person picks up
When a machine isn’t enough.
HAL reaches every frontier model and uses the right one for each question. When none of them is enough, it offers you a Hal: a real person who picks up the conversation where it was.
- You ask.By voice, wherever you are.
- HAL answers.By voice, or projected on the wall.
- A Hal picks up.If that isn’t enough, HAL offers a person. You say yes, and someone real answers.
Intelligence
The technology of a self-driving car. In your hand.

How you use it.
Projection
Any wall. Any table. A screen.
Set it down and it projects what you asked for: always in focus, no cables, no screen to turn on.
40–60″Full HD in a dim room. Up to 100″.
Always in focusLaser projection on a wall, a table or your palm.
No time limitOn its base. Up to 2 h at 30 lm on its own battery.¹
Any screenOver Wi-Fi to a monitor or a TV, no cables.
The recipe on the kitchen wall. Movie night, nothing to set up. The lights, even without internet.
With HAL
What comes with it, and what may cost later.
What it does
- Answers by voice or projects the answer.
- Runs three models on the device, and accepts your own.
Included with Monolith
- The link to HAL.
- Over-the-air updates, free.
- The on-device models.
- 3-year warranty, replacement included.
Needs internet
- Frontier models in the cloud.
- Talking to a Hal.
- Updates.
- Without internet: voice on the device, local models, your home over Thread, Vault Mode.
May cost extra later
- Sessions with a Hal are paid in HAL, as they are today.
- Some frontier models may need a HAL plan in the future.
- If anything changes, we will say so before it ships, not after.
Connected everywhere
Ten radios. One object.
It picks the pathOver the best path available: Wi-Fi, 5G, satellite or through another Monolith.
When there is no signal
Another Monolith is the bridge.
No Wi-Fi, 5G or satellite? A nearby Monolith carries the link over LoRa: the swarm. If one has signal, they all do.
Where your data lives
Three places. You always know which.
On the device
- The NPU runs HAL’s models here: your voice and your data are processed on the device, not in the cloud.
- Your personal memory lives encrypted on the device. Neither HAL nor we can read it.
In the secure element
- Your keys and your wallet live in a separate chip. They never leave it, not even toward HAL.
What travels, encrypted
- Only what matters travels to HAL, end-to-end encrypted, post-quantum.
- Every request goes through the agent firewall, with permissions per agent. If an agent tries to send what it shouldn’t, Monolith stops it and tells you.
- Capture.Camera, microphones, radar and GNSS generate data on the device.
- Process.The NPU filters and summarizes locally: only what matters travels.
- Transmit.Encrypted, over the path Monolith picks.
- Protect.Secure enclave and end-to-end post-quantum encryption.
- Respond.HAL answers by voice or projects data onto any surface.
- Encrypted backup
- Photos, notes and records are encrypted with keys from the secure element and backed up to the network. How the network works →
- If you lose it
- Your data comes back on a new Monolith with your recovery phrase.
- Vault Mode
- When the radios go off, the node disconnects with them.

A hidden camera. Your call.
Under the glass: a 48 MP camera, a depth sensor and an infrared emitter. It records only while the red light is on.

04 — Top
Your wall is now a display.
The entire top face is black sapphire. Behind it, a laser projector that never needs focusing.

All of this. In 11 millimeters.
An AI processor, a vault for your keys, a silicon-carbon battery and a sound system — two exciters in the glass and a woofer in the body.

06 — Back
The other side.
The charging coil with its ring of Qi2 magnets, the passive radiator that carries the bass, and the vapor chamber that cools without a fan.

Materials

01
Black titanium
A grade 5 titanium chassis with a black DLC coating. It doubles as the antenna, with insulated breaks inside that are invisible from the outside.

Long-lasting battery
A silicon-carbon anode and a low-power coprocessor that keeps everything asleep until it's needed.
Up to 12 days standby¹
05
The base
It aligns it with magnets, stands it at an angle to project, and carries its own 5,000 mAh battery and a 10 W woofer: six hours of projection with no outlet. A solar cell on top charges it slowly in the sun; it does not replace the charger. Any Qi charger works too. There isn't a single connector.

Passive cooling
A vapor chamber against the titanium: no fans, no noise.

The squeeze cuts the radios.
Hold the edges for three seconds: 5G, satellite, Wi-Fi, Bluetooth, Thread, UWB, NFC, LoRa, GNSS and radar lose power. Not a setting: the circuits are off.
RF power cut-off
02
The red light is the rule.
A tiny red light under the glass turns on whenever the camera or microphones are recording. Turn it face down or cover it with your palm, and a dedicated circuit cuts camera, microphones and radar.

03
Keys in a separate chip.
Your private keys and biometric templates live in a dedicated secure element, apart from the main processor. They never leave it, not even toward HAL.

Months without charging
With the radios off, consumption is minimal: in Vault Mode the battery lasts months.¹ The solar cell on the back adds a trickle charge in the sun (on the order of 0.1 to 0.3 W) that stretches it further; it does not replace the charger.

Questions
What people ask.
Does it replace my phone?
Yes. Your number lives inside on an eSIM: calls, messages and WhatsApp, by voice, and what you need to see, it projects.
What if HAL stops existing?
Monolith is built to keep working without us. The models run on the device, your data is backed up encrypted on the decentralized network of nodes, and Monoliths connect to each other.
Which apps does it run?
Every one we can make work, starting with the ones you already use for calls and messages, like WhatsApp, plus HAL’s apps.
Which countries and carriers?
The standard ones: any carrier that offers eSIM, on the standard 5G bands. The premiere is in the United States, on April 3, 2028.
Do I need a HAL account?
Yes, and it’s free. Joining the list creates it for you.
When does it arrive?
We’ll let you know. You get your number now, and we email you when there is a date, in list order.
