Sentridock · A Narrative

The boundary between AI
and everything you protect.

A story in fourteen beats — about the PC, the rise of AI, and the architectural choice that defines this decade.

1981

Scene 01 — The first revolution

Since the 1980s, the personal computer has been one of the defining revolutions of modern life.

02

Scene 02 — Four decades of accumulation

For four decades, people have worked through PCs over the human-machine interface.

Billions of machines. Decades of workflows. Institutional knowledge, confidential data, and personal identity — all accumulated behind that interface.

03

Scene 03 — The most important machines of all

And the most sensitive ones are deliberately cut off.

Not because the work is small. Because the work is too important to expose.

Scene 04 — The second revolution

Then, in 2023, a second revolution began.

05

Scene 05 — Accelerating

AI is advancing at a pace
no prior technology has matched.

Approaching human cognition. In many domains, surpassing it.

06

Scene 06 — The defining question

How does AI help people work with
the PCs they already have?

Installed Base

Frontier AI

⟡

At the scale they already exist —
including the ones that cannot be connected at all.

07

Scene 07 — The first path

Put AI inside the PC?

Edge AI · Rejected

Frontier models at the edge.

The most capable models don't live at the edge. They live in data centers. That is where they will stay.

08

Scene 08 — The second path

Put AI on the PC?

Computer-Use Agents · Rejected

OpenCUA. Operator. Computer Use.

The agent bypasses the HMI. It reads data directly from the system and controls the PC through privileged interfaces — no screen required.

The human at the keyboard becomes a bystander. Activity happens on their own machine, under their own account — and they never see it.

And in an air-gapped system, installing such an agent breaks the air gap itself.

09

There must be a boundary.

— Silence —

10

Scene 10 — The boundary

Sentridock restores the HMI as the only channel between AI and the PC.

Protected

The PC

Permitted

The AI

The AI sees only what Sentridock permits it to see. The PC — and everything inside it — remains sovereign.

11

Scene 11 — What crosses the boundary

Confidential data is transformed at the boundary.

PC Side

AI Side

entity: user_01

AI receives what it needs. The PC keeps what matters. Sovereignty, intact.

12

Scene 12 — The air gap holds

Even where AI has never been allowed before.

Because Sentridock is the boundary, the air gap is never broken — only bridged, on terms you control.

13

Scene 13 — What remains

AI becomes what it was always meant to be.

Not a replacement for the person at the keyboard.
Not a risk to them.
An amplifier of them.
