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 everything. Text first, voice next, video on the way.

• Persona Genesis

  An adaptive interview that senses where your richest material is - your persona's completeness visible as it grows.

• Voice Twin

  Your timbre and intonation from a 10-15 minute sample; real-time conversation with under 1.5s latency.

• Truth Anchor

  Facts come only from your biography. On the unknown, an honest "let me check with the real me" - never an invention.

• Blind Twin Test

  Someone close to you cannot tell the twin from you in chat. Our quality metric - and our favorite demo.

A featherlight earpiece that rests on the bone behind your ear. Sound travels through bone conduction - your ears stay open to the world, and only you can hear your twin.

• Whisper I/O

  Bone conduction out - only you can hear. Near-silent input back. A conversation invisible to the room.

• Earshot Brief

  Walking out of your meeting, you hear the 90-second brief of the one your Meeting Ghost attended.

• Name Whisper

  Someone approaches - your twin whispers the name, the context, the last thing you agreed. No more "hey... buddy."

• Instant Answer

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

• Offline Twin, honest by design

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

The platform stage: your twin, wherever you already work - not another app to open, but a presence inside the ones you use.

• 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 - investor, coach, editor - from us and third-party developers.

• Fidelity Score

  The likeness standard grown from 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 audited.

Our long-term research direction: what happens when your twin no longer needs a screen or a speaker at all - when remembering something your twin knows feels like remembering 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 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 - signals your body already produces - partnerships with the pioneers of 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 toward the most personal interface ever built.
