# Offline & Air-Gapped AI: What Works With No Internet

> Yes for answering, no for anything fresh: what a local AI assistant keeps doing with no internet, what stops, and the test for a truly air-gapped deployment.

Offline & Air-Gapped AI

# Does an Offline AI Assistant Really Work
With No Internet Connection?

What actually keeps working with the network gone, what quietly stops, and the
three-state test that separates a truly air-gapped deployment from one that merely
tolerates being offline.

Built from real buyer questions in our sales meetings

Switch the network card off and ask your AI assistant a question. What happens next tells
you almost everything about what you bought. A cloud assistant goes silent, because the
intelligence was never on your machine; a genuinely local assistant keeps answering,
because it was. AirgapAI is built for the second outcome, and executives evaluating it ask
one question before almost any other: *does it really work with no internet
connection?*

Direct Answer

**Yes for answering; no for anything that needs fresh information.** A genuinely
local assistant keeps responding with the network adapter switched off, because everything
inference needs — the model weights, the embedding step, the retrieval index — lives
on the machine itself. Iternal builds AirgapAI to run 100% local on the laptop and keep
working with the network card turned off.

**The limit: nothing refreshes itself.** With no network, the assistant
cannot open a browser, cannot fetch a public document, and cannot answer about anything newer
than the loaded model's training cut-off. Its data set has no way to know the source content
changed. Keeping models and data sets current is work your team owns, and the first model load
reaches the machine over a network or from removable media, because the installer does not
bundle a model.

**What leaves the machine is a short list you can verify.** Inference never leaves
the device. The one outbound behavior is an optional update check, which can be switched off
entirely or pointed at a file server inside your own network. Licensing adds nothing to the
wire: the license key AirgapAI issues is verified on the device itself, against a public key
built into the application, so there is no activation server and no phone-home. Put each of
those on your security questionnaire — Iternal answers the
[targeted questions below](#outbound-traffic) in writing.

**Offline-tolerant and air-gapped are different standards.** Offline-tolerant means
the product survives losing the network; fully air-gapped means the machine never has a route
out at any point in its lifecycle. AirgapAI is designed to operate either way, and what
survives the loss of connectivity is set out below. For more information on where the software
installs, visit the

happens to what you type, visit the

## What Keeps Working When the Network Is Gone

The reason a local assistant survives losing the network is architectural, not a feature
toggle. Everything inference needs — the language model's weights, the embedding step
that turns your question into a vector, and the retrieval index built from your loaded data
sets — lives on the device's own disk and runs on its own silicon. There is no round
trip to score, so there is nothing for a dead connection to interrupt.

In practice that means the things people actually do day to day keep working: asking
questions of the loaded model, searching and chatting against the data sets already on the
machine, and running saved workflows. Iternal states it plainly: AirgapAI runs 100% local
on the laptop and keeps working with the network card turned off — a claim you can
reproduce on your own hardware during evaluation, and Iternal encourages exactly that
test. Iternal originally designed AirgapAI for the U.S. military, where disconnected
operation is the entry ticket.

## Fully Air-Gapped, Offline-Tolerant or Cloud-Dependent: The Three-State Test

“Air-gapped” gets used loosely in AI marketing, and the looseness is where
evaluations go wrong. Buyers ask whether the product can still touch the firm's own
server, whether local installation alone keeps it walled off, and whether results can be
moved out of a sealed environment. Each is a version of the same underlying question:
*which of three states is this deployment actually in?* The table below separates
the three and gives you the test that proves each one:

| State | What it means | The test that proves it |
| --- | --- | --- |
| Cloud-dependent | Inference happens on someone else's machines. The app on your device is a window, not an engine. | Disable the network: answering stops entirely. |
| Offline-tolerant | Inference runs on the device, but the deployment expects to touch a network occasionally — the first model download, an optional update check. | Disable the network after setup: everything already loaded keeps answering; nothing new arrives. |
| Fully air-gapped | The machine never has a route out. Install files, models, data sets and updates all arrive by removable media or a file server inside your own network. | Install, load a model, add a data set and take an update — with no route to the internet at any point in the lifecycle. |

The last row is the demanding one, and it is the one to get in writing before you buy. A
product can be genuinely local at inference time and still assume connectivity at install or
update time — that makes it offline-tolerant, which is enough for a five-hour flight
and not enough for a closed-loop classified network. AirgapAI operates in the fully
air-gapped state — the license key it issues is verified offline against a public key
baked into the application, and updates can be served from an internal file server. The first model load still has to reach the machine from
somewhere, because the installer does not bundle a model: plan that transfer as part of
deployment.

## What Still Requires a Network — and What Does Not

Four things genuinely cannot happen on a machine with no route out:

- The first model load. The model does not ship inside the installer
— the right model depends on the user's device
— so it reaches the machine over some network once, or by removable media.
- Refreshing a data set when its source changed. Running offline, the app
has no awareness that source content changed; a data set is rebuilt and re-loaded by a
person.
- Keeping local models current. Described as left to the customer; new
model versions arrive the same way the first one did.
- The application update check. An optional outbound call — the
next section turns its exact behavior into questions Iternal answers in writing.

One thing conspicuously absent from that list: **license activation**. AirgapAI
does issue a license key, and the application verifies it on the device against a public
key baked into the build — so no activation server, no license check over the network
and no phone-home is needed to keep the product running. Confirm the licensing mechanics
in your contract when you buy.

## What Leaves the Machine — and How to Pin It Down

Iternal's account of outbound traffic is short. Inference never leaves the device, and
the application does not retrieve documents from the cloud. The one outbound behavior is
an optional update check — a ping to Iternal's update server that can be switched
off entirely, or pointed at a file server inside your own network so updates arrive
without an internet route. Licensing adds nothing to the wire: the license key is
verified offline on the device, with no activation server and no phone-home. The mark of a
well-run evaluation — for any local-AI product, AirgapAI included — is turning
each statement into a question answered in writing, and Iternal welcomes all four:

Pin it down: questions for your evaluation

- Is the update check enabled in the build we will receive, and can we see it switched off before install?
The one outbound behavior described for the product, confirmed as a setting rather than a promise.
- Can application and model updates be staged from a file server inside our own network?
Whether a sealed environment can stay current with no internet route at any point in the lifecycle.
- Is there any activation, telemetry or usage-reporting traffic at any point in the product lifecycle?
That the update check is the complete list of outbound behavior — in writing, on your security questionnaire.
- During the pilot, can we image one machine and monitor its traffic from first startup?
The answer on your own wire, which outranks any datasheet.

## Where People Actually Work Without a Connection

Disconnection is a working condition, not an edge case. Again and again, buyers described
connectivity that drops — or was never there — exactly
where their people do the work. In their own words: airplane connectivity is a problem a lot
of the time, and airplane wi-fi “costs a lot of money and never works”; cloud
coding assistants do not work on a five-hour flight; cellular coverage is weak at factories
far from city centers; client environments do not always have ubiquitous connectivity.

Others described environments with no internet connection
at all, where anything cloud is ruled out from the start: a grid operator that cannot run
anything other than an offline system, closed-loop classified networks with no access to
cloud services, critical-infrastructure supply chains that are completely sealed, and field
engineers working in plants with no access to the outside world — where an engineer
cannot even look up a switch command. For those buyers the question is not whether offline
operation is convenient; it is the entry ticket.

## What Disconnected Operation Rules Out

The other half of the answer. Offline:

- No browser access from inside the assistant.
- No retrieval of public documents — users download and package them into a data set manually.
- No industry research or external sourcing pulled into a document it drafts.
- No answers about recent events beyond what the loaded model was trained on.
- A data set that does not update itself, because the app offline has no awareness the source content changed.

None of these are defects of a local architecture; they are what “no network”
means. The evaluation mistake is expecting a sealed machine to behave like a connected one.
The planning mistake is not assigning a person to the refresh loop — someone owns
rebuilding data sets when source content changes, and moving new models onto the machines,
because the software cannot do either for itself.

FAQ

## FAQ: Offline and Air-Gapped AI

The machine never has a route out at any point in the lifecycle — install, model load, data sets and updates all arrive by removable media or a file server inside your own network. That is stricter than running inference locally: a product can be fully local at answer time and still assume connectivity at install or update time, which makes it offline-tolerant, not air-gapped. The test: can you install, load a model, add a data set and take an update with no internet route at any point?

A local assistant does — the model, embeddings and retrieval index are on the device, so answering continues with no connection. Cloud assistants do not: buyers have told us that cloud coding assistants fail on a five-hour flight and that airplane wi-fi is expensive and unreliable. The limit travels with you, though: nothing on the machine refreshes itself until it is back on a network or fed by removable media.

Yes, if the model and the data sets they need are loaded before they go — that is the pattern buyers repeatedly described for factories with weak cellular coverage, plants with no outside access, and client sites without reliable connectivity. The operational requirement is a refresh loop: someone rebuilds and re-loads data sets when source content changes, because the app offline has no awareness anything changed.

No activation server is involved. AirgapAI does issue a license key, and the application verifies it on the device against a public key baked into the build, so nothing about licensing requires a network: no activation call, no license check over the wire, no phone-home. Confirm the current licensing mechanics in your contract when you buy.

Not inside the installer — the right model depends on the user's device, so AirgapAI does not bundle one. The first load reaches the machine over some network once, or by removable media; in a sealed environment, models and updates can be staged on a file server inside your own LAN. Plan that transfer as part of deployment, not as an afterthought.

## Test It With the Network Card Off

Disconnected operation is checkable in an afternoon: install AirgapAI on one machine,
load a model and a data set, switch the network card off, and work. What answers is real;
what stops is the refresh loop you will need to own. If disconnected operation is your
requirement, that one test tells you more than any datasheet.
