About this app

Airgap is the private LLM client for Android — connect to any AI model, self-hosted on your own server or through a hosted provider like OpenRouter, OpenAI, or Groq. No middleman: your device connects directly to the endpoint you choose. No data collection.

Connect any OpenAI-compatible endpoint and Airgap is the mobile client you've been missing.

WHO IS THIS FOR?

Airgap works with any OpenAI-compatible endpoint — your own server or a hosted provider.
• Developers running Ollama or LM Studio on a home machine
• Users connecting to OpenRouter, OpenAI, or Groq without a middleman app
• Privacy-first users who want direct, unproxied AI access
• Home lab and self-hosting enthusiasts
• Teams evaluating private LLM deployments

PRIVACY BY ARCHITECTURE

Airgap is not "privacy-focused" as a feature — it's private by design.

• No relay — your device connects directly to the provider you choose
• No app account or sign-up required
• No chat content collected by Airgap — only sent to your configured server
• No analytics on conversation content
• API keys encrypted and stored locally
• Open connection — you see exactly where your data goes

WHY AIRGAP?

Most AI apps route your prompts through corporate servers. Airgap does the opposite — it talks directly to the provider you choose.
Whether you're running a 7B model on a Raspberry Pi, a 70B model on a multi-GPU rig, or using OpenRouter for hosted models, Airgap gives you a polished mobile interface without the middleman.

No middleman. Airgap doesn't relay or store your chats. Just your device and the endpoint you choose.
