A state-of-the-art local AI model running entirely on your Mac. Your prompts never leave the device. Works offline, on a plane, behind a firewall, on sensitive client work. No cloud, no account, no API key, no subscription, no telemetry. GDPR-compliant by construction.
Nothing ever leaves your Mac — not even in the background. Enforced by the macOS sandbox, not by policy.
Zero network code paths. No URLSession, no sockets, no telemetry SDKs in the binary. Auditable. You can drop Wi-Fi mid-sentence and keep typing.
Your prompts, attachments, and responses never leave the device. Nothing is sent to a vendor, cached on a server, or used to train a model. For typical confidentiality clauses that prohibit disclosure to third-party cloud services, Airplane AI removes the disclosure vector entirely.*
No personal data is transmitted, stored on a remote server, or processed by a third party — there is no third party. Article 6 lawful basis and Article 28 processor agreements don't apply when no processor exists. Your SwiftData store lives in your user container and stays there.
The app ships with com.apple.security.app-sandbox and nothing else. No network, no outgoing connections, no file-system access outside its own container. CI blocks the build if forbidden symbols (URLSession, NWConnection, WKWebView, analytics SDKs) appear anywhere in the binary.
€29.99 one-time on the Mac App Store. No subscription. No per-seat pricing. No kill-switch. Your copy keeps working on macOS 15+ whether we ship new versions or not.
A state-of-the-art local AI model, Metal-accelerated on Apple Silicon. Streams tokens sub-second after warmup. Not a demo, not a toy — real open-weight quality, running locally. What model and why →
* "NDA-safe for the general case" means that for typical NDAs prohibiting disclosure to third-party cloud services or generative AI vendors, Airplane AI eliminates the disclosure path because no such vendor exists in the data flow. Some NDAs have unusual clauses — always read your specific agreement. We can't read it for you.
Cloud AI: offline. Airplane AI: keeps going.
Upgrade, wait, or log in again. Airplane AI has no limit.
NDA. Medical. Legal. Airplane AI never leaves your Mac.

That is the sum of two and two. $ airplaneai -p "Explain closures" -n "swift-learning" A closure is a function together with the variables it captured from its surrounding scope… $ airplaneai -p "Give me an example" -n "swift-learning" --continue Sure — here's a minimal Swift closure that captures a counter… $ airplaneai --list swift-learning (4 msgs)
No API keys. No sign-up. No configuration.
We ship Google's open-weight Gemma 3n Effective-4B model (~4B-param quality, mixture-of-experts design). Q4_K_M quantization keeps the weights dense enough to stay sharp on writing, coding, and reasoning while fitting comfortably in 16 GB of RAM with headroom for the OS, browser, and your real work.
Why Gemma 3n. Open weights (Gemma Terms of Use), state-of-the-art efficiency at this size class, multilingual, handles code, respects instructions, and runs well under llama.cpp with Metal acceleration. No vendor lock-in — the same weights are public and auditable.
Why Q4_K_M. Four-bit K-means quantization preserves almost all of the reasoning quality of the full model while cutting RAM use by ~4x. It's the sweet spot between file size and answer quality for 16–24 GB Macs.
URLSession, NWConnection, or any analytics SDK ever appears.One purchase. No subscription. Includes the GUI and the airplaneai CLI.
App Sandbox. Zero network entitlements. No telemetry, no analytics, no crash reporting. Verified by CI scripts at every build.
