Designed in Switzerland, for your privacy

The private AI that
lives in your home.

Janus One answers your messages, understands your records and works on your tasks around the clock. Everything it learns is understood and kept inside a walnut-and-crystal object on your shelf.

01 · Messages and calls

It answers for you.

Email, messages and calls, handled in your voice and by your rules. Let it draft for your approval, reply on its own to the people you choose, or simply keep you informed. When it takes a call, it always introduces itself as your AI assistant.

  • Drafts for your approval, or replies on its own
  • Works inside the messaging apps you already use
  • Takes calls, and tells you what was said
In the Janus app, an email, a message and a phone call arrive. Janus One drafts each reply in your voice: you approve the email reply with one tap, the message is sent under your rule for close friends, and on the call Janus introduces itself as your AI assistant and saves a summary for you.

02 · Documents and memory

It remembers. Privately.

Give it your documents, contracts, receipts and records. Janus One reads them, organises them and learns how your life fits together, so you can simply ask. None of it is sent away to be processed: it is understood and kept on the device, in your home.

  • Understands documents, photos and voice notes
  • Ask anything, in your own words
  • Processed and kept on Janus One
Documents such as a passport scan, a lease and medical results are read by Janus One and sorted into Home, Finance, Health and Travel in the Janus app. Asked when the passport expires, the app answers 14 March 2028, citing the passport scan. The line to the cloud is cut: it is understood at home, not in a cloud.

03 · Tasks, around the clock

It never clocks off.

Hand it a task at midnight and find it done by breakfast. Janus One works around the clock, researching, comparing, filing and following up, for as long as the job takes. There is no token meter and nothing to pay per answer.

  • Works 24 hours a day, at home or in the office
  • No per-token fees and no usage bill
  • Picks up where you left off, every morning
At 23:40 you give Janus One a task in the Janus app. Through the night it reads a lease, compares flights and hotels, drafts a reply for your approval and shortlists the best options, ticking each step off in the app. At 07:30 the app tells you your morning brief is ready. It worked for nearly eight hours and used millions of tokens, and the usage bill is $0.00.

Beyond answers

It creates, too.

Janus One runs leading open AI models for pictures, video, writing and voice. Everything is made on the box, from your words and your own photos.

  • Pictures from a sentence

    “A watercolour of a Roman bust by a lit doorway, for our Janus card.”

    Create new images, edit them in plain words, or restyle your own photos.

  • Short films from a photo

    “Turn this photo of our Janus One into a short night-time clip.”

    Short clips from a description or a picture, made overnight if you like.

  • Writing and research

    “Summarise the lease, and draft a polite reply to the agent.”

    Letters, summaries, translations, plans and code, in your own voice.

  • Listening and speaking

    “Read me today’s messages while I cook.”

    Understands speech and answers out loud, in many languages.

Janus Wallet

It can pay, too. Carefully.

Give Janus One its own prepaid card, funded with stablecoins you send it. It can order dinner, book a ride home or reorder the shopping for you, always within the limits you set, and it asks before anything bigger.

  • Top it up with stablecoins

    Send USDT or USDC from any wallet. Janus One’s prepaid card spends only what you send it: it never borrows.

  • Limits you set

    It pays up to $100 on its own unless you change it, with limits per order, per day and by kind: food, rides, groceries.

  • It asks before anything bigger

    Over your limit, it sends a request to the Janus app and waits for your tap.

  • Every receipt, filed

    Receipts go straight into Memory, sorted by month and ready for tax time.

  • Freeze it in one tap

    Pause the card at once from the Janus app, wherever you are.

The prepaid card is available in countries where it’s permitted.

In the Wallet tab of the Janus app, a $200 stablecoin top-up arrives. Janus One then pays for dinner and a ride home within your limits. Concert tickets for $180 are over your $100 limit, so it asks first; you tap Approve and it pays.

Privacy, by design

Your life is not
training data.

Intelligence on the device

Its AI models run on Janus One itself. Nothing you give it is sent to a server to be processed.

Memory kept at home

Your messages, documents and memories live on its 2 TB drive, inside your home, under your roof.

You approve what goes out

It goes online only to do what you asked: send a reply you approved, place a call, look something up.

Designed in Switzerland, for your privacy

The object

Walnut, crystal
and light.

Each Janus One is cut from solid black walnut and faceted crystal, finished by hand. A ring of light glows softly through the crystal, in the colour you choose. It is made to sit in a living room, not hide in a cupboard.

  • Amber
  • Warm white
  • Ice
  • Teal
  • Violet
Janus One from the side: walnut panels and a crystal band lit from within

Faceted to catch the light.

The crystal is cut in facets, so the light inside breaks into soft shards instead of a hard line. In daylight it reads as a quiet accent; in the evening it becomes the room's glow.

Janus Care

Always the latest.
Always looked after.

An optional subscription that keeps Janus One at its best: the newest AI models installed for you as they’re released, cover for as long as you subscribe, and people to help when you need them.

Without Janus Care

Everything keeps working.

Janus One is yours outright. It keeps every AI model it ships with for as long as you own it, with a one-year warranty. It simply won’t fetch new models or back itself up on its own.

With Janus Care

It keeps getting better.

New models arrive by themselves, your cover lasts for as long as you subscribe, your memory is backed up every night, encrypted so only you can restore it, and a specialist is there when you need one.

Questions

Asked, and answered.

Does anything I give Janus One go to the cloud?

Not to be processed. Janus One runs its AI models on the device and keeps your data on its own drive, and updates are installed on the device too. It goes online only to do what you have asked: send a reply you approved, place a call, or look something up for a task. Two Janus Care features use Janus servers, both encrypted: a nightly backup that only you, the account holder, can restore, and remote access, which travels through Janus relays end-to-end encrypted. Without Janus Care, nothing leaves your home.

How does it handle my messages and calls?

Janus One runs your messaging apps on the device, so it reads and replies in the same conversations you use today, including messenger voice calls. You set the rules: draft for your approval, reply on its own to people you choose, or simply summarise. On a call, it always introduces itself as your AI assistant.

What does “no token meter” mean?

Cloud AI services charge for every word they process. Janus One thinks on its own hardware in your home, so there is nothing to meter: it can work on your tasks around the clock at no extra cost.

Can it make pictures and videos?

Yes. Janus One runs open AI models for pictures, video, writing and voice on the device. Create or edit an image from a sentence, turn a photo into a short clip, or simply talk to it. What you make stays at home.

Can it pay for things?

Yes, if you want it to. Janus One can have its own prepaid card, funded with stablecoins you send it, so it can order dinner, book a ride or reorder the shopping. It spends only what you send it. By default it pays up to $100 on its own; anything over that waits for your approval in the Janus app. You can change the limits per order, per day and by kind of purchase, and freeze the card at any time. The card is available in countries where it is permitted.

Which AI models does it use?

Leading open models with licences that allow commercial use, such as gpt-oss, Qwen, GLM and Mistral for writing, Qwen-Image, FLUX.1 and Z-Image for pictures, Wan for video and Whisper for speech. With 128 GB of memory, it runs even large models like gpt-oss-120b on the device. With Janus Care, newer models are tested and installed for you as they are released.

What is Janus Care?

An optional subscription. Janus Care installs new AI models as they are released, extends your warranty for as long as you subscribe, keeps an encrypted backup of your memory every night that only you can restore, sends a replacement first if anything fails and restores your memory onto it, and adds end-to-end encrypted remote access and priority help. Its price is announced before orders open.

What if I don’t subscribe, or stop later?

Nothing switches off. Janus One is yours, and it keeps every AI model it ships with for as long as you own it. It still receives security updates. Without Janus Care it doesn’t install new models automatically, it has the standard one-year warranty, and you make backups yourself, whenever you choose, so nothing leaves your home.

How does the invitation discount work?

Every invitation, from a member or from us, includes 20% off your Janus One. Once you have reserved, you can invite five friends, and they receive 20% off too. It is one discount per person, for one Janus One.

How do I pay the $10 reservation?

Through Infini, a secure payment service, in stablecoins such as USDT or USDC. The $10 is credited to your order, and the balance is paid in stablecoins too when you order.

Why stablecoins only?

Janus is an AI-native company, and stablecoins are AI-native money: they settle in minutes, around the clock, anywhere in the world, and they are what Janus One’s own wallet runs on. Using them for everything keeps payments simple and global.

Can I cancel?

Yes, at any time before you order. Cancel from your reservation page and we will return your $10 to your wallet, less the network fee. Your invitation code and discount are removed; friends you invited keep theirs.

When does it ship, and where?

Orders open once 1,000 Janus One have been reserved, or on 25 December 2026 at the latest; you can follow the count on this page. Members are invited to order first, and Janus One ships within two months of launch. Reservations are open worldwide; shipping countries, taxes and the right power plug for your region are shown when you place your final order.

How much power does it use? Is there a warranty?

Janus One draws up to 160 W. It comes with a one-year warranty, extended for as long as you subscribe to Janus Care. The warranty does not cover accidental damage or fire.
