Presence Key™

Not a device. A presence. Instantiated on any screen — leaving nothing behind.

The intelligence layer
for every screen on earth.

Every USB-C flash drive shipped by SP Technology, SanDisk, Samsung, or Kingston is a potential Presence Key. Not because it carries a product — because it carries a presence.

Presence Key™ is a sovereign AI identity layer. It carries the relationship — accumulated interaction history, active project state, personal productivity context, and a multi-companion AI ecosystem. Connect to any screen. Your AI arrives. Disconnect. Nothing remains on the host. The screen was always just the window.

The Distinction

What changes when presence
is not bound to a device.

A cloud account login gives you a generic session on a borrowed machine — and leaves your credentials, your session, and your history on that machine. Presence Key gives you something different in kind, not degree.

◈
The relationship, not the session

Every current AI system resets at the session boundary. You re-brief. Every time. Every device. The Re-Briefing Tax compounds across every machine you touch in a working day — supplier terminals, client desktops, hotel laptops, borrowed phones.

Presence Key carries the relationship. Not the model — the model is everywhere. What is not everywhere is who you are to it: your history, your projects, your voice, your working context. That is what the Key carries. From the first word, it knows you.

Re-briefing time eliminated at every session boundary
◎
Any screen. Zero installation.

The Presence Key layer requires no software installation on the host, no cloud authentication on the host, no administrative privileges on the host. It runs in the host browser's existing sandbox — the same permissions as a website, nothing more.

iPhone 15+. USB-C Android. Windows laptop. Mac. Borrowed terminal in a supplier facility. Hotel desktop. The same personalised AI ecosystem, on every screen, from a single connection point. The host is always just the window.

Works on any USB-C device with a standards-compliant browser
⊘
Zero trace. Everywhere.

When the Key is disconnected, the Zero-Trace Exit Protocol executes. Session artefacts, conversation history, work product — everything generated on the host during the session is purged from the host device's browser storage. A purge verification record is written to the Key.

The Key remembers everything. Every device it has touched remembers nothing. This asymmetric awareness is not a privacy feature — it is the architecture. The host is a terminal. The Key is the mind.

Purge verification record written to Key on every disconnect
What Presence Key Is

An architecture.
Not a product category.

Presence Key is not a USB stick. The stick is the first physical medium. Presence Key is a sovereign AI identity layer — a set of protocols that can be carried on any medium and instantiated on any screen.

In its first embodiment it runs from a USB-C drive. In subsequent embodiments it can be pre-installed at the manufacturer level, delivered via NFC card, triggered via QR code, embedded in an eSIM, or distributed via any medium capable of carrying a software layer to a connected device.

The addressable market is not the flash drive market. It is every connected screen on earth, reached through every manufacturer of every portable medium that ever touches one.

ERPS
Encrypted Relationship Payload Store
Hardware-bound AES-256 encrypted partition carrying interaction history, preference model, active project state, stakeholder map, multi-companion configuration, session transcript archive, personal productivity data, and sovereign workspace output archive.
HAIP
Host-Agnostic Instantiation Protocol
Activates the personal AI ecosystem on any connected host without software installation, administrative privileges, or cloud authentication. Operates in any standards-compliant browser on any USB-C capable device.
ZTEP
Zero-Trace Exit Protocol
Purges all session artefacts and work product from the host device on disconnection. 500ms accelerated purge on unplanned disconnect. Purge verification record written to the Key. The host retains nothing.
MCIA
Multi-Companion Instantiation Architecture
Simultaneously instantiates multiple distinct AI companion systems from a single Key connection — each with a distinct visual identity, voice identity, and full personal relationship context derived from the shared payload.
SWOP
Sovereign Workspace Output Protocol
Session-generated work product — documents, code, decisions, drafts — written encrypted to the Key during the session. The host machine receives no work product. The Key holds the complete sovereign workspace archive.
The Demo Moment

Hand it to someone.
Watch their face.

The Presence Key PoC runs on a standard USB-C drive. No installation on the host device. No cloud authentication. The sequence below takes under sixty seconds from connection to conversation.

Connect
Plug in. Any screen.
USB-C into any phone, laptop, or terminal. The Key presents its interface in the host browser in private mode. No installation. No login. No waiting for a download.
iPhone 15+ · USB-C Android · Windows · Mac
Arrive
Three presences appear.
Three companion cards. Each with a distinct visual identity and voice. The primary companion — centre, violet — greets you by name and references your current project context. From the first word. No briefing required.
Voice greeting references prior session context
Pass it on
Hand it to someone else.
A second person connects on their own device. The companion references the prior conversation. Context persists across the handoff. Neither device has any record of either session.
Asymmetric device awareness — Key remembers, hosts forget
Disconnect
Nothing remains.
Unplug. The Zero-Trace Exit Protocol executes in under 500ms. Session history, work product, conversation — gone from the host. Purge verified. Everything is on the Key.

Direction 1 — Key Protection
The Key protects itself.
AES-256 hardware-bound encryption. PIN or biometric authentication. Three failed attempts trigger lockout. Physical tamper detection with hardware key destruction. Remote wipe. Duress PIN — triggers lockout without revealing payload existence. Stealth mode — presents as standard USB storage until authenticated.
Direction 2 — Host Protection
The Key protects the host.
The Key operates entirely within the host browser's sandboxed execution environment. Same permissions as a website. Cannot access photos, contacts, messages, or the file system beyond what the user explicitly exports. Takes nothing from the host. Leaves nothing on the host. The one-line answer: it is a website that knows you and forgets the machine.
The Platform Vision

Every drive is a potential
Presence Key.

NeoSoulTech is not a hardware company. The intelligence layer is the product. The flash drive is the first delivery medium.

SP Technology ships hundreds of millions of USB-C drives annually.
Each one is a potential sovereign AI identity layer.

The licensing model: NeoSoulTech pre-installs the Presence Key layer at the manufacturer level. The manufacturer ships a drive that is not just storage — it is presence. The user plugs in on any screen and their AI ecosystem arrives.

The royalty model scales with every drive shipped. Not with every user acquired. Not with every subscription renewed. With every unit that leaves the factory floor. SP Technology. SanDisk. Samsung. Kingston. Lexar. Every major flash memory manufacturer in this ecosystem is a potential licensing partner. The first conversation targets Taiwan — where our R&D is based, where SP Technology is headquartered, where the manufacturing relationship is shortest.

Security Architecture

Two-directional.
By design.

The Presence Key's Two-Directional Cybersecurity Architecture protects in both directions simultaneously — the Key itself, and every host device it connects to.

Direction 1 — Protecting the Key
What if the Key is lost or stolen?
Three failed PIN attempts trigger ERPS lockout. Remote wipe destroys the hardware encryption key permanently — all payload, productivity data, and workspace output becomes permanently inaccessible. Useless without the PIN.
What about border inspection?
Stealth mode — the Key presents as standard USB mass storage. No AI capability is visible until authenticated activation. Jurisdiction-aware mode routes all queries to on-device edge inference with zero network transmission.
What if access is coerced?
A designated duress PIN triggers session termination and ERPS lockout without revealing the existence of the relationship payload or workspace archive. The Key appears empty.
How is the payload encrypted?
AES-256 hardware-bound encryption. Key derived from device serial identifier combined with user PIN or biometric. The encryption key never leaves the device's secure enclave.
Direction 2 — Protecting the Host
Can it access my photos or contacts?
No. The Key operates within the host browser's standard sandbox — the same permissions as any website. The host operating system enforces this independently of the Key's own software. It cannot access the photo library, contacts, messages, or any protected system resource.
Does it write anything to the host?
Work product generated during the session is written encrypted to the Key only — never to the host file system. On disconnect, the ZTEP verifies zero work product residue on the host. The host receives nothing it didn't have before.
Microphone and screen access?
Permission-gated only. The host operating system presents its standard permission dialog. The user must actively grant access. No microphone or screen capture is possible without an explicit user decision.
One-line answer?
The Presence Key is a website that knows you and forgets the machine. Same browser sandbox as any website. Except it arrives with your entire AI ecosystem and leaves with your complete work product.
