The basics
- What is a digital twin of a person?
- A private AI model of one real person: how they think, speak, decide, and remember. They build it, they own it, and they control who ever gets access.
- How is Sona different from ChatGPT or a normal chatbot?
- General-purpose assistants respond from broad training and the context in a prompt. A Sona twin also uses the personal material you choose to provide. And it has to pass the recognition test: someone who knows you well, in a blind chat, cannot tell you apart.
- How is Sona different from Character.AI or Replika?
- Sona is built around a verified person and approved personal data. It can support communication and selected tasks within permissions set by the owner. Built on consent, measured likeness, and quantum-safe security.
- Is a digital twin a deepfake?
- Sona is designed for verified, consent-based identity modeling. Its output is labeled as AI and may carry provenance data so recipients can verify the source.
Building and using your twin
- How do I create an AI version of myself?
- You talk to Sona for a few short sessions and connect whatever material you choose to share. It learns your style, your values, and your story, and becomes a twin you can message today and call later.
- How long does it take?
- A useful text twin starts working in your first few sessions, and it keeps getting closer the more you talk to it.
- Can my twin act on my behalf?
- Yes, within limits you set. It assists first, asks before acting, and logs every action.
Ownership, privacy, security
- Who owns my data?
- You do. We never sell it, and we do not use it to train anything shared. You can export or delete your twin at any time.
- How is my twin protected from quantum computers?
- Sona uses NIST-standardized post-quantum algorithms in supported parts of its architecture. The Security page explains the implementation.
- Can I delete my twin?
- Yes, permanently, in one tap.
Memory, legacy, ethics
- Is Sona resurrection of the dead?
- Sona is an AI service for living users. Any future legacy feature should follow the owner's recorded instructions and applicable law.
- Can I preserve my parent's voice and stories?
- Yes, with their consent. They build their own twin and you can sit with them while they do it, and it keeps their voice and their stories close.
- What happens to my twin after I die?
- Only what you decided in advance. Inheritance happens on your terms, with verification and family governance.
Link, Neural, and what is next
- Is Sona Link a real product I can buy?
- Link is in development and is not currently available for purchase. We will publish availability and specifications when they are confirmed.
- Will Sona put a chip in my brain?
- Sona Neural is an early research direction focused on non-invasive interfaces. It has no announced product or launch date.
- Why build hardware at all?
- Hardware could make the twin available in more situations with less screen interaction.
- Will my twin work outside the Sona app?
- Sona OS is planned as an API and SDK for integrations with approved email and business tools. Availability and supported services have not yet been announced.
