Business Pill · Local says where it lives. Egress says what leaves.
Egress means what leaves the box, and where it goes. The video shows a man who keeps his diary in a locked drawer, and a helper that still has to send a note out to answer a simple question.
A short explainer video, under a minute. The diary and the helper are an illustration of the idea.
At a glance
What Egress Is
He is surprised. The diary never moved, but a question did.
How It Works
The video follows it in three steps. Something stays in the box.
Why It Matters
The video turns this into one question: what leaves, and where does it go?
Our report on Ghost’s $3,499 Core shows the idea in a product. The report says Ghost’s home page states: “No data ever leaves your home.” It also says Ghost’s support page states that Core “runs its AI and stores its memory locally” and, in the same answer: “You’ll still need an internet connection to access features like web search, email and over-the-air software updates & fixes.”
From our news coverage
The report also says the privacy policy states: “Online features can still send task information to external services.” This is the lesson’s idea in a company’s own words: where something lives and what leaves it are separate questions. The report presents all of this as Ghost’s own account, and this publication verified none of it independently.
The Business Engineer Lens
Where this idea sits in the Business Engineer library:
The Business Engineer framework maps where each part of the AI stack sits and who holds the leverage. These pills are short lessons from the same library.
Sovereign AI builds on Egress. Sovereign AI asks where patient records go; egress says location is not enough, ask what leaves and where.
Egress contrasts with On-Device AI(lesson unlocks soon). On-device says the data stays put; egress asks what still leaves, such as a question the assistant sends out.
Trusted Execution(lesson unlocks soon) constrains Egress. A sealed room lets data go in while only the combined result comes out, controlling what leaves.
Shadow AI(lesson unlocks soon) is an example of Egress. Pasting contracts into a personal chatbot is company data leaving to a place nobody approved.
