Your digital twin. It thinks like you, acts for you, and stays.
Sona creates a second you - your style, your memory, your voice. Today it takes the busywork: drafts in your voice, decisions talked through, meetings covered. Tomorrow it is simply with you - an earpiece away. Not a chatbot. You.
Launching soon. You will own everything, and you can delete it in one tap.

A scripted preview. A real twin runs on your voice, your history, and your rules - and asks before it acts.

What Sona is, in one sentence
A digital twin is a private AI model of one real person - how you think, speak, decide, and remember - built with your consent and under your control. Sona builds yours, makes it useful every day, and keeps it safe for a lifetime.
Your best self is leaking away
In life
You cannot be in two places. You drown in messages, meetings, and decisions, and the sharpest version of you gets spent on routine. By evening there is nothing left for the things that actually matter.
Over time
The way you think is your sharpest asset - and it is written down nowhere. Your reasoning, your taste, your instincts live only in your head, spent daily on routine and never captured. The same is true of the people who shaped you.
Alone
And every tool you use starts from zero. Assistants, apps, AI - none of them know your whole story, so all the help you get is generic. Advice for everyone is advice for no one.
Every tool captures your data.
None of them captures you.
That is the gap Sona fills.
Meet the second you
Sona builds a twin that genuinely acts like you, then puts it to work in your life.
Thinks it through with you.
Talk a hard decision through with yourself from the outside. Your twin asks the questions you would ask and shows you the blind spot you are standing in.
Writes in your voice.
Emails, replies, and briefs drafted the way you would write them, ready for one tap to send. It learns from your edits - and hands you an hour of routine back every day.
Goes to meetings for you.
Where you allow it, your twin attends what you cannot - listens, answers the routine by your rules, and gives you a 90-second brief when you walk out of yours.
Remembers everything for you.
What did I promise? What did we decide? Where did I see that? Instant answers across your whole life - and reminders before deadlines, not after.
And when you want it to, it keeps what matters - your voice, your stories - safe for the long run. Built on consent, control, and dignity.

The recognition test
How we know it is really you
We hold ourselves to one hard test - the recognition test: someone who knows you well, in a blind chat, cannot tell whether they are talking to you or to your twin.
Same question, sent to two chats. One is a person. One is their Sona twin.
Honestly? Run the version where you stay and the version where you go, then check which one you keep talking yourself out of. That's usually the one you actually want.
Don't decide it as a job - decide it as a year of your life. What do you lose if you stay, and is that a story you'll be at peace telling later?
That is the bar. Not a clever bot, but unmistakably you. And we treat it as a real measurement, not a feeling: blind conversations, scored and repeated, until how much it sounds like you becomes a number. Every part of Sona is measured against it.
Illustration of the recognition test.
Four reasons Sona is not just another AI
It is really you, not a chatbot.
Most AI sounds like everyone. Your twin sounds like one person: you. And we measure that - blind conversations with people who know you, scored until "sounds like you" becomes a number, not a feeling.
It acts, it does not only talk.
Companions chat. Sona works. It drafts your emails, preps your briefs, talks decisions through, and covers the meetings you cannot attend - always under your control.
Yours forever, and yours alone.
You are the owner. You see everything, you can erase anything, and you decide who ever gets access. Protected with quantum-safe encryption built to outlast the technology that could one day threaten it.
A memory that lives like yours.
Your twin remembers the way you do - the important vividly, the trivial dimly - and recalls the right thing at the right moment. Your people, your promises, your decisions. Nothing worth keeping gets lost.
Things only a second you can do
Once a twin genuinely knows you, it unlocks help no generic AI can give.
Advice from your future self.
A twin that has lived your history can answer as the you of ten years ahead - your trajectory and your goals, extrapolated honestly, in your own voice.
Rehearse before it counts.
Prepare for the hard conversation against a simulation of the other side, built from public data and clearly labeled as one - and walk in ready.
You, in 30 languages.
Your twin speaks languages you never learned - in your voice, in your style. For experts and creators, that is a global audience overnight.
A day without your phone.
Your twin takes the incoming, settles the routine itself, and interrupts you only on your own definition of urgent.
Your twins, in the room together.
Send your twin to settle the routine with your colleagues' twins - it comes back with a decision for you to approve, every step audited.
Always a whisper away.
With Sona Link, the coming bone-conduction earpiece, your twin whispers the name you forgot and the answer you need - heard only by you.
Built to be safe for a lifetime - even against a quantum computer
Some secrets need to stay secret for decades, not months. Your twin is one of them. So we protect it with a new kind of encryption designed to survive even the powerful quantum computers that experts expect in the future. In plain terms: we are locking your most personal data with a lock that tomorrow's most powerful machine still cannot pick.
Sona's Vault uses post-quantum cryptography based on the NIST-standardized algorithms ML-KEM (key exchange) and ML-DSA (digital signatures), alongside strong encryption in transit and at rest. We are not inventing exotic physics - we are applying the standards built precisely for the post-quantum era, today, instead of waiting until "harvest now, decrypt later" attacks make old encryption a liability.
A digital twin is meant to last a lifetime and beyond. Encryption that is "good enough for now" is not good enough for something you intend to keep forever.

Let us be clear about what Sona is not
Not a deepfake tool.
You can only build a twin of yourself, as a verified person. Everything your twin generates is cryptographically signed, so it is always clearly a Sona twin - never an impersonation of a live human.
Not another generic assistant.
Most AI answers like a helpful stranger. Your twin answers like one person - you - grounded in your style, your values, and your real history. That difference is the whole point.
Made for the living, first.
Every twin is built by a real person, about themselves, while they are here. Whether anything is ever kept or shared later is a choice that stays entirely with its owner.
One identity. Three bodies.
Sona is not just a chat. It is a system - your twin in text, your voice on a call, your presence across the surfaces of your life. It will clear your plate - drafts, briefs, meetings - and then it is simply with you: the next bodies for your digital self, so the second you is not an app you open, but a presence that is always there.

Questions people ask about Sona
- What is a digital twin of a person?
- A digital twin of a person is a private AI model of one real human - how they think, speak, decide, and remember - created with their consent and controlled by them. Sona builds yours and keeps it secure.
- How is Sona different from a chatbot like ChatGPT?
- A general chatbot answers like a helpful stranger. A Sona twin answers like one specific person: you. It is grounded in your style, values, and real biography, and it is built to pass the recognition test - someone close cannot tell it apart from you.
- Is this resurrection of dead people?
- No. Sona is for the living. Every twin is made by a real person, about themselves, while they are alive. Preserving and one day passing on a twin is an option the owner controls, with consent and care built in.
- Who owns my data, and can I delete my twin?
- You do. You can view everything, change who has access, and permanently delete your twin at any time. We never sell your data.
- How is my twin protected from future quantum computers?
- Sona's Vault uses post-quantum encryption based on NIST standards (ML-KEM and ML-DSA). In plain terms, it is a lock designed so that even a future quantum computer cannot pick it.
- Can my twin act on my behalf?
- Yes, within limits you set. It can draft messages, give advice, and cover routine meetings - and bring you the brief after. It always assists first and asks before it acts, and every action is logged.
