Two Worlds, One Soul

You live your life on the right — collecting memories, training your AI. But you prepare for the left — encrypting secrets, setting up your Dead Man's Switch. We bridge these two worlds.

Protect What Matters

Military-grade encryption meets human compassion. Your secrets are guarded by the same technology that protects governments.

The Vault

Bank-grade AES-256-GCM encryption with zero-knowledge architecture. We can't see your secrets — and neither can anyone else.

Zero-Knowledge Proof

The Trigger

A 5-level monitoring system that checks if you're okay. If you don't answer, we execute your digital will — automatically.

5-Level Dead Man's Switch

The Delivery

Your loved ones receive exactly what you leave them — passwords, letters, crypto keys — encrypted and delivered with care.

Automated Inheritance

Live Forever

Not a chatbot. A digital you. Train your AI twin with your personality, your voice, your memories — and let it speak for you when you no longer can.

The Brain

A 29-dimensional personality matrix captures who you really are — your humor, your wisdom, your quirks. Not just words, but soul.

29-Dimensional Persona

The Voice

Clone your voice with just 5 seconds of audio. Your grandchildren will hear you speak — your real voice, your real warmth.

Neural Voice Synthesis

The Connection

Your AI twin calls your family on birthdays and anniversaries. Real conversations, real memories, real presence — even when you're gone.

AI Phone Calls

Security You Can Trust

We don't just promise security — we prove it with zero-knowledge architecture.
