About Sona
We are building personal AI that carries your context forward
Sona preserves selected personal context so it remains useful as the user’s work and circumstances change.
The problem we could not ignore
Valuable context often disappears when people change roles or lose access to old systems. It can also become unavailable when a person can no longer share it directly. That stopped being acceptable the moment the technology to preserve it existed. So we built a way to keep it, and to put it to work while you are here.
Why we build the hard part
The technology to assemble a convincing twin, meaning voice, face, and language, is now something you can buy. We develop the product in stages and publish the questions that still need work. We build the part that is hard. The team works on persona fidelity and reliable data capture. User rights shape both areas. That is a defensible position, and it is the right one.
Sona brings personal AI and digital identity into tools built for long-term memory.
Sona is a digital twin: a private AI model of one person, built by that person. Nobody owns this category yet, and we intend to be the name people trust in it. We are starting in the US, UK, EU, Canada, and Australia, for individuals and businesses alike.
One identity across three product stages
Your Sona twin lives in chat today, and it will not stay there. Next comes Sona Link, a bone-conduction earpiece that keeps your twin within whisper distance, and after that Sona Neural, our long-term research direction. The goal is that you stop opening an app and simply have your twin with you. Each stage ships only when it has earned your trust.
Explore the roadmapProduct commitments
Consent first. Honest about what a twin is. Quantum-safe. Always clearly labeled as AI. A free tier that does real work, always. We would rather grow slower and keep that trust than grow fast and break it. We are a small team and we are not hiding. Every one of our names goes on this page before launch, because a product that verifies your identity should not ask you to trust an anonymous "we".
