Built in Vienna, Austria. GDPR safe by architecture.

GDPR safe by design

There is no data transfer. So there is nothing for the GDPR to regulate.

Most cloud AI tools hand you a Data Processing Agreement and call it GDPR compliance. A DPA is paperwork that governs a data transfer you should not have needed in the first place. Airplane AI has nothing to agree to, because there is no data transfer. Not a packet. Not a row. Not a byte. Your Mac reads the input, the local model writes the answer, the conversation sits in the macOS App Sandbox. The entire GDPR machinery around processors, controllers, and cross-border flows simply does not light up.

Your computer. Your AI. Your data.

The AI runs on your computer. Nothing leaves it.

This is their AI, on their computer. You buy Airplane AI once, the model sits inside the app bundle, and every token it produces is computed by your own Mac's CPU and GPU. The developer is not your processor under GDPR Article 4, because there is no processor: you are the only party involved. No server read your prompt. No vendor saw your answer. Nothing leaves your machine.

Article 28: no DPA needed

Nothing to sign. Nothing to negotiate.

Article 28 requires a signed DPA when you send personal data to a third-party processor. Airplane AI does not send personal data anywhere. No DPA, no Standard Contractual Clauses, no appendix of approved sub-processors. Your legal team can close the tab.

Article 9: health, legal, HR, children

Sensitive categories stay on-device by definition.

Medical records, legal files, employee data, therapy notes, biometrics, data on minors. Under Article 9, processing these in cloud AI is a legal minefield of explicit consent, derogations, and impact assessments. With Airplane AI, there is no cloud processing. The obligation does not arise, because the trigger does not fire.

Chapter V: no international transfer

Your data never leaves the EU. It never leaves your room.

Schrems II, Schrems III, the Data Privacy Framework, the next framework that replaces it: all of them worry about EU data flying to the United States. Airplane AI is not a data flow. Your Mac is the whole system. The GDPR Chapter V obligations do not apply, because there is no transfer to gate.

Article 22: no automated decisions on you

The model suggests. You decide.

Article 22 regulates automated decisions that produce legal or similarly significant effects. Airplane AI only generates text when you press Send. Nothing is applied to you. Nothing scores you. Nothing ranks you. You are the decision maker, always.

Verified by your DPO in 10 minutes

A technical constraint, not a promise.

Open Activity Monitor, Network tab, filter for Airplane AI. Watch bytes-sent stay at zero. Open the app bundle's entitlements file: there is no network-client or network-server key. Every build is blocked at CI if any network symbol (URLSession, NWConnection, WKWebView) appears in the binary. Policy is easy to change. This is not a policy.

NDA safe by design

The D in NDA stands for Disclosure. We disclose nothing. We cannot.

An NDA is a Non Disclosure Agreement. The one verb it prohibits is disclosure to a third party. Airplane AI has no third party to disclose to. The app has no network entitlement, so the operating system itself blocks every outbound connection. Nothing you type, paste, or dictate ever leaves the Mac in front of you. That is the contract your NDA was trying to enforce, written into the binary.

No disclosure vector

Nothing leaves your device. Not even by accident.

The core concern in every confidentiality clause is disclosure to third parties. Airplane AI removes the disclosure vector entirely. Your prompts are processed locally and never transmitted anywhere. There is no third party to disclose to, no training pipeline to leak into, no vendor logs to subpoena, no employee to read a log.

Client work, M&A, litigation

Use it on your most sensitive projects.

Draft NDAs. Review contracts. Summarize deposition transcripts. Analyze deal memos. Work that your NDA would never allow you to paste into ChatGPT is safe in Airplane AI, because nothing leaves the room.

For your legal team

Show them the entitlements file.

The app ships with a single entitlement: app sandbox. No network access entitlement exists. Your legal team or DPO can read the entitlements file in under a minute and confirm: outbound connections are architecturally impossible.

* NDA stands for Non-Disclosure Agreement. The D is for Disclosure. Airplane AI discloses nothing to anyone. Your data never leaves your Mac. It cannot. That covers the disclosure angle completely. But every NDA is different. If yours contains clauses beyond non-disclosure, such as restrictions on tools, software categories, or specific obligations around AI use, read those carefully. We do not know what else is in your NDA. Nobody does except you and the other party.

The answer is always yes

Safer than opening it in Excel.

If you would feel safe opening a file in Excel on an airplane, you can feel safer opening it in Airplane AI. We do not send your prompts to any cloud. We cannot. There is no cloud. There is just your computer, with a statistical model, an LLM, running locally on it, inside the macOS App Sandbox, without any network capability.

Personal data in a spreadsheet

Can I drop a CSV with customer data into Airplane AI?

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.

Confidential client work

Can I summarise a confidential contract I received under NDA?

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.

Health, legal, HR records

Can I paste medical notes, payroll, or therapy transcripts?

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.

Trade secrets and unreleased work

Can I ask Airplane AI about our unreleased product?

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.

Student data under privacy laws

Can I grade papers or analyse student work?

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.

The thing your DPO actually asks

Can you demonstrate zero network traffic?

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 network truth

Every other AI and office tool phones home. We cannot.

Not by policy. Not by promise. By kernel-enforced macOS sandbox. The entitlements file has no network key, so the operating system refuses outbound connections for us.

Figures reflect the default configuration of each product as shipped in 2026. Enterprise plans can sometimes narrow the scope with paid contracts and data-processing agreements. Airplane AI needs no plan upgrade and no DPA, because there is no data transfer to agree on in the first place.

Works anywhere

On a plane. In a tunnel. In the middle of nowhere.

Every other AI stops when your connection does. Airplane AI keeps going. Always.

Airplane mode, literally

Drop Wi-Fi mid-sentence. Keep typing.

The model runs entirely on your Mac's GPU. No ping to a server. No loading spinner waiting for a response. Turn on airplane mode right now and ask anything. It works because there is nothing to connect to.

Trains, tunnels, hotels

Terrible hotel Wi-Fi is no longer your problem.

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.

Corporate firewalls

Your IT department cannot block it.

Many enterprises block external AI services at the firewall. Airplane AI makes no outbound connections, so there is nothing to block. It works on the most locked-down corporate network because it does not use the network at all.

Who uses Airplane AI

Finally: an AI you're actually allowed to use.

Every other AI sends your words to a cloud server. That's why your compliance team said no. Airplane AI is different. Everything stays on your Mac.

Lawyers & Legal Teams

Client confidentiality isn't optional. Airplane AI never touches your client data. It never could. There is no server to send it to.

Doctors & Therapists

Patient data stays in the room. GDPR Article 9 and HIPAA apply to cloud AI. They don't apply here, because nothing leaves your Mac.

Consultants & Advisors

Every engagement is under NDA. Your client's strategy goes nowhere. Not to OpenAI. Not to Anthropic. Nowhere.

Finance & HR Professionals

Salary data, performance reviews, M&A strategy. Numbers stay in the room. Like a good CFO.

Researchers & Academics

Pre-publication data is your IP. Your research trains nothing. Not now, not ever, not in a future update.

Anyone tired of subscriptions

ChatGPT costs $240/year. Airplane AI costs €29.99 once. No renewal. No subscription. Updates within the current major version are included.

Where it saves you

Works when every other AI can't.

On a flight

Wi-Fi just died.

Cloud AI: offline. Airplane AI: keeps going. Works at 35,000 feet. Works in the subway. Works in the middle of nowhere. No signal needed.

Under NDA

You can't send that anywhere.

Client contract. Patient notes. M&A strategy. Airplane AI never leaves your Mac. Your prompt never touches a server. Not even for a millisecond.

🇪🇺 GDPR & compliance

Your DPO said no to cloud AI.

And they were right. Airplane AI is engineered to keep your content on your Mac, not by checkbox. No data transfer means no data transfer risk. The obligation doesn't exist if the transmission doesn't exist.

Rate limits

"You've reached your limit."

Upgrade, wait, or switch to the slower model. Airplane AI has no limit. Nobody else is on the queue. It's your Mac. It runs as fast as your Mac runs.

The math

Free for 14 days. Then one dinner out. Then never again.

You get the full app free for the first 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. Here is what the industry actually charges per year for comparison, from entry plans to the flagship ones that keep showing up in 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.

How it works

Download. Open. Chat.

No account. No setup. No API key. Just AI on your Mac.

  1. 1
    Download from the Mac App Store.

    The AI model is bundled inside. Nothing to configure, no separate download, no account to create.

  2. 2
    Open the app.

    Loads onto your Mac's GPU. Ready in seconds. Works without Wi-Fi from the first launch.

  3. 3
    Ask anything.

    Type, paste images, dictate with your voice. Everything stays on your Mac. Nothing is sent anywhere.

Why it's actually private

Every other AI promises privacy.
We make it impossible to break.

Most AI tools say "we respect your privacy." We say: the app physically cannot send your data anywhere. macOS enforces that at the kernel, not in a terms of service.

No internet access

The app cannot reach the internet.

Not "we don't send your data." The operating system prevents it. We verify this at every build. You can verify it yourself: open Activity Monitor, search for Airplane AI, check the Network tab. Zero bytes. Always.

No account means no identity

We don't know who you are.

No email. No login. No payment history linked to your questions. We can't know who's asking what. There's no connection between you and us at all.

Your words train nothing

Your questions disappear when you close the app.

The AI model is frozen. It cannot learn from you. Your conversations are stored only in your own Mac's local storage, and only if you want them to be.

Questions

Everything you want to know.

Is it safe for work covered by NDA?
For the general case: yes. Your prompts never leave your Mac. Nothing is sent to a vendor. Nothing is cached on a server. If your NDA prohibits sharing client information with third-party AI services, Airplane AI removes that path entirely. There's no third party. There's no disclosure. Read your specific NDA for unusual clauses. Every NDA is different.
Is it engineered to keep your content on your Mac?
By construction, not by promise. GDPR obligations are triggered by personal data leaving your control. Airplane AI ensures data never leaves your Mac. No data transfer means no data processing obligation. No processor agreement needed because there's no processor. A lawyer or DPO can verify this in under 10 minutes.
Does it actually work without Wi-Fi?
Yes. That's the whole point. The AI model lives inside the app. Everything runs locally. Drop Wi-Fi mid-conversation. Keep going. Fly. Work underground. Travel to a conference with unreliable hotel Wi-Fi. It doesn't matter.
How good is the AI?
For everyday work: excellent. Writing, editing, coding, research, translation, analysis, summarizing, brainstorming. It uses Google's open Gemma model, running at full speed on your Mac's GPU. Expect answers in under a second. It won't do what GPT-4 can do with a million-token context and live web search. But for the private, focused work you actually need AI for, it's more than enough.
Why buy this when ChatGPT has a free tier?
ChatGPT's free tier uses your conversations to train future models, requires an account, needs internet, and rate-limits you constantly. Airplane AI is private, offline, unlimited, and owned, not rented. And if you're using AI for confidential work, ChatGPT's free tier isn't an option at all.
What are the requirements?
Mac with Apple Silicon (M1 or later), macOS 15 Sequoia or later, and 16 GB of RAM minimum. If you have a newer MacBook Pro or MacBook Air, you're almost certainly set.
How big is the download?
About 4.5 GB. The AI model is bundled inside the app. Nothing to download separately, no configuration. Big download once, then it's done.
What happens if my Mac breaks?
It's a Mac App Store purchase. Redownload it on any Mac with your Apple ID. No extra charge.
What you need

Three things.

Own your AI.
Pay once. Done.

Free for 14 days. €29.99 once after that. One payment on the Mac App Store, no renewal, no account. Works offline, anywhere your Mac goes.

Zero-network invariant

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.
