From a twin you talk to, to a twin that is simply there.

The digital twin at the heart of Sona. It thinks like you, speaks like you, drafts and advises in your voice, and remembers what you tell it. Text first, voice next, video after that.

• Persona Genesis

  An adaptive interview that follows whatever you have most to say about, with your persona completeness visible as it fills in.

• Voice Twin

  Your timbre and intonation from a 1 to 5 minute sample, with real-time conversation under 1.5 seconds of latency.

• Video Twin

  Face, expression, and gesture for calls and recorded messages, built from a short video sample.

• Truth Anchor

  Facts come only from your own material. When your twin does not know, it says "let me check with the real me" instead of guessing.

• Blind Twin Test

  Someone close to you cannot tell your twin from you in chat. It is our quality metric and our favorite demo.

An earpiece light enough to forget, resting on the bone behind your ear. Sound travels through bone conduction, so your ears stay open to the world and only you can hear your twin.

• Whisper I/O

  Bone conduction out, so only you can hear it. Near-silent input back. A conversation the room cannot see.

• Earshot Brief

  Walk out of your own meeting and hear the 90-second brief from the one your twin covered.

• Name Whisper

  Someone walks up. Your twin whispers the name, the context, and the last thing you two agreed. No more "hey... buddy."

• Instant Answer

  Any question, hands free and eyes up, answered from your own knowledge, promises, and decisions.

• Offline Twin, honest by design

  Wake-word detection and core answers run on the device, with no network needed. And people always know when Sona is in the room.

The platform stage: your twin inside the tools you already work in, rather than one more app to open.

• Persona API / SDK

  Your twin inside mail, CRM, messengers, and games - strictly under the rules in your Consent Registry.

• Skill Store

  New abilities for your twin, built by us and by third-party developers. An investor's eye, a coach's questions, an editor's red pen.

• Fidelity Score

  The likeness standard built on our Blind Twin Test: certification for any digital human, the way FICO scores credit.

• Sona Rooms

  Your twin meets your colleagues' twins, settles the routine, and brings you a decision to approve. Every step is logged.

Our long-term research direction: what happens when your twin needs neither a screen nor a speaker, and recalling something your twin knows feels like recalling it yourself.

• Intent Layer

  Ask without words: non-invasive EEG/EMG wearables read "ask my twin" as intent - the answer arrives by voice through Link.

• Persona-for-BCI

  Sona as the personality layer for other people's neural hardware. They build the electrodes, we bring you.

• Recall Mode

  The far goal of the research: your twin's knowledge feeling like your own memory. To recall as easily as to think.

We are starting where responsible teams start. Non-invasive interfaces, meaning signals your body already produces. Partnerships with the people who pioneered brain-computer interfaces. And the same rule that governs everything we make: nothing happens without your explicit, revocable consent. We publish our thinking as we go. No promises, no dates, just honest research into the most personal interface there is.
