ChatGPT, Claude, and Gemini need servers, accounts, and a connection. Airplane AI needs your Mac.

Not by promise. Not by a toggle you can flip off. By the macOS sandbox itself. The entitlements file has no network key, so the operating system blocks outbound connections for us before they can happen. Compare us to the tools already on your Mac.

Figures reflect each product's default configuration as shipped in 2026. Enterprise plans can sometimes narrow the scope with paid contracts and DPAs. Airplane AI needs no plan upgrade and no DPA, because there is no data transfer to agree on.
Here is what that means for your work, in two parts.
Words you type, files you drop, photos you attach, audio you dictate, every reply the model writes, every chat kept in history. All of it lives on your Mac, in the app's sandbox, under your user account, on your disk.
The model itself is a file shipped inside the app, roughly four gigabytes. When you ask a question, your Mac reads that file and writes the answer. Nothing travels over the internet, because the app has no way to travel over the internet. No URLSession, no NWConnection, no network-client entitlement. If we wanted to send a packet, macOS would refuse.
The app is free for 14 days. No card, no sign-in, no ping. You open it, you use it, the 14 days tick down locally, on your Mac.
When you buy anything inside the app, Apple's App Store handles the payment. Apple charges your Apple ID. Apple sends the app a receipt. Apple tells the app you paid. Your card number goes to Apple, not to us. Your chats do not go anywhere. The App Store never sees them.
Today, the one thing to buy is the Unlock after your free trial. Restore Purchase works the same way: one tap, Apple answers, done.
No other network activity ever occurs, at any other moment, for any reason, initiated by anything. Not a licence check. Not an update ping. Not a telemetry beacon. Nothing.
Non-Disclosure Agreements prohibit disclosure to a third party. We have no third party to disclose to. The app cannot reach one. That is the whole disclosure analysis for the tool itself. Your specific NDA may add clauses beyond non-disclosure (tool approvals, AI-use restrictions), so read yours. The disclosure vector itself is closed by the binary.
GDPR regulates the transfer and processing of personal data. When you use Airplane AI, no transfer happens between you and us, or anyone. So no processor agreement, no DPA, no lawful-basis analysis attaches to your in-app work. The supervisory authority has nothing to supervise on our side, because no personal data flows to us, or to anyone else, from your use of the app.
Without trusting a word we say: read the entitlements file, run Activity Monitor with a Little Snitch deny-all rule. Bytes out stay at zero, except when you tap Unlock.
Verify it yourself, one command:
codesign -d --entitlements :- /Applications/Airplane\ AI.app
Four keys appear. None of them lets the app touch the network.
If you would feel safe opening a file in Excel or Word, you can feel much much safer opening it in Airplane AI.
Long, sophisticated, impressive. A calculation over a very large set of frozen numbers, and still just a calculation. Any computer that can do the arithmetic can run it. Your Mac can. The model does not need a data center. Big tech wanted you to believe otherwise, because their servers are how they charge you, meter you, log you, and train on you. You never actually needed them. Airplane AI moves the calculation back to where it always could have run: your computer.
Yes. The CSV is read on your Mac and extracted to text by the app, entirely on-device. No row, no name, no email, no phone number leaves this machine. Unlike ChatGPT, Copilot, or Gemini, where every pasted row becomes part of a vendor's request log.
Yes. Paste the PDF or drag it into the chat. Apple PDFKit extracts the text on your Mac. Airplane AI reads the text locally. The contract, the clauses, the counterparty, the dollar amounts, none of it leaves your device. There is no outbound path to leak through.
Yes. GDPR Article 9 sensitive categories. Attorney-client privileged material. Employee information. Cloud AI turns every paste into a cross-border transfer. Airplane AI keeps the paste inside the macOS App Sandbox and inside your building.
Yes. Unreleased code, patents in flight, unannounced launches, M&A draft memos. None of it is indexed, logged, or sent to a training pipeline. There is no training pipeline. The model is frozen, bundled, and read-only.
Yes. FERPA in the US, national data-protection laws in the EU. Cloud AI makes every student essay a disclosure event. Airplane AI makes it a local file operation. Your Mac reads it, the local model summarises it, you close the app, done.
Yes. Open Activity Monitor, Network tab. Filter for Airplane AI. Watch the bytes. They stay at zero. Check the app's entitlements file. There is no network entitlement to grant or revoke. A DPO can verify this in under ten minutes without trusting any claim we make.
The model runs on your Mac's GPU. The Wi-Fi bar is irrelevant.
Turn on airplane mode. Ask anything. The answer arrives as fast as your Mac can write it. No loading spinner, no retry, no apology.
Conference Wi-Fi with 500 people on one router. Train tunnels at 250 km/h. Underground car parks. Remote job sites. Wherever you are when you need to think, Airplane AI is already there.
Deep packet inspection, strict egress rules, captive portals. None of it matters, because the work does not go over the wire in the first place. Open the app, get your answer, move on.
Work your compliance team used to forbid with cloud AI. Draft it, review it, summarise it, polish it, without the paperwork.
Draft contracts. Compare clauses. Summarise depositions. Turn a thirty-page filing into a five-bullet brief before your next call.
Dictate a session note. Reshape a referral letter. Turn handwritten scribbles into a tidy patient summary before the next appointment.
Draft the client memo. Sharpen the deck outline. Turn three interview transcripts into one clear narrative on the flight home.
Salary bands, performance reviews, board prep. Draft, rewrite, compare scenarios at the speed of thought.
Rework an abstract. Reformat a methods section. Pressure-test an argument before a reviewer does. Pre-publication work stays pre-publication.
ChatGPT Plus is $240 a year, every year. Airplane AI is €29.99, once. No renewal. Updates within the current major version are included.
At 35,000 feet the other tools show a spinner and a sorry. Airplane AI shows your next paragraph. It was always running locally.
Client contract, patient note, deal memo. Paste it, work with it, delete it, close the laptop. The work happens inside one window on one machine.
Cloud AI: buy in-flight Wi-Fi, sign in, watch it time out. Airplane AI: open laptop, type, done. The draft lands before the plane does.
SaaS AI has a meter, a queue, an account, a tier, a receipt, a ToS update, a model that keeps changing. Airplane AI has none of those, because it is not a service. It is an app. Everything you stopped noticing about the other tools, we do not do here.
Write a hundred drafts. Rewrite them. Run the same prompt twenty times. It is your Mac, it runs as fast as your Mac runs, and nothing meters it.
Nothing to sign up for, nothing to forget, nothing to reset. You open the app on your Mac and you use it, the same way you open Preview or TextEdit.
The app has one version and you have all of it. No pay-per-token anxiety, no "3 queries left today" banner, no bucket to top up.
The model is a file bundled inside the app. Nobody changes it on you. No morning where a behaviour you relied on disappears.
Full app free for 14 days, no card required. After that, one payment of €29.99 unlocks the current major version for good. No monthly bill, no seat licence, no renewal. For comparison, here is what the industry actually charges per year, from entry plans to the flagship tiers in the headlines.
Break even vs. the cheapest subscription in six weeks. Break even vs. Google AI Ultra in under four days. After that, every month is free. No renewal. No seat licence.
Public list prices, consumer tiers where available, monthly rates converted to annual. Enterprise plans, education discounts, and annual prepayment discounts vary. Airplane AI has one price, one payment, within the current major version.
No account. No setup. No API key. Just AI on your Mac.
The AI model is bundled inside. Nothing to configure, no separate download, no account to create.
Loads onto your Mac's GPU. Ready in seconds. Works without Wi-Fi from the first launch.
Type, paste, drop files, attach images, dictate with your voice. Get answers.
Free for 14 days. €29.99 once after that. One payment on the Mac App Store. No renewal. Works on a plane.

Airplane AI makes no outbound network connection at any time, under any circumstance, whether initiated by the user or automatically. No user content (text, audio, image, chat history, metadata) ever leaves the device. The only network traffic the operating system may perform on the app's behalf is Apple's StoreKit flow for in-app purchase and receipt validation, which carries no user content and is triggered only by an explicit user action on the purchase or restore screen.
