A path from today’s software twin to ambient and research-stage interfaces

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

  A real-time video representation based on the visual material you provide.

• 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

  Evaluated through consented recognition tests with people who know you. It is our quality metric and our favorite demo.

A lightweight earpiece concept designed to sit behind the ear. Sound travels through bone conduction, so your ears stay open to the world and only you can hear your twin.

• Whisper I/O

  The concept combines bone-conduction audio with low-volume input for more private interaction.

• 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.

A platform for using your twin in approved apps and workflows.

• Persona API / SDK

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

• Skill Store

  Add specialized workflows created by Sona or approved developers.

• 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 is exploring how a consented persona layer could work with future brain–computer interfaces.

• 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. This is an early research direction without a launch date. We will publish updates when the work is ready for external review.
