## What is AirplaneLLM?

AirplaneLLM is a private AI chat app that runs entirely on your device — and keeps working even when you have no signal at all.

WORKS ANYWHERE, EVEN WITH NO SIGNAL

On a plane. Deep in a tunnel. On the subway, on a mountain trail, in the basement, or anywhere the bars drop to zero. Once the AI model is downloaded, AirplaneLLM needs no internet connection. Airplane mode is no problem.

No more "no connection" errors. The AI is right there on your phone, ready whenever you are.

TRULY PRIVATE

No accounts. No cloud. No data sent away. Your messages and chat history never leave your device, because there is no server to send them to. What you type stays with you.

FAST AND ALWAYS AVAILABLE

The AI runs locally, so there is no waiting on a network. Open the app and start talking.

WHAT YOU CAN DO

- Ask questions and get instant answers
- Brainstorm ideas and organize your thoughts
- Draft emails, messages, and notes
- Summarize and rewrite text
- Practice a language or just have a casual chat

HOW IT WORKS

On first launch, the app downloads a compact AI model to your device (a one-time download that needs some free storage and a connection). After that, everything happens on-device, offline. You can delete your conversation history at any time, and uninstalling the app removes the model and all data from your device.

PLANS

AirplaneLLM is free to try. A paid plan (monthly, yearly, or lifetime) unlocks unlimited continuous chat and all features. Subscriptions renew automatically unless canceled; manage them in your store account.

Note: AI responses are generated automatically and may be inaccurate. Please verify important information, and do not rely on the app for professional advice.

Privacy stays on your device. Connection never required. Start chatting with AirplaneLLM today.
