Airgap: Private AI Chat

Airgap connects your iPhone or iPad to any AI model — self-hosted on your own server or through a hosted provider like OpenRouter, OpenAI, or Groq. No middleman: Airgap doesn't relay or store your chats.

Connect any OpenAI-compatible endpoint — self-hosted (Ollama, LM Studio, vLLM, llama.cpp, LocalAI) or hosted (OpenRouter, OpenAI, Together, Fireworks, Groq). No accounts, no subscription to any AI provider.

Connect in seconds

1. Start your LLM server or get an API key from a hosted provider
2. Enter the endpoint address in Airgap
3. Pick a model
4. Chat from your phone — anywhere

Built for any AI workflow • Streaming chat responses • Markdown rendering with code syntax highlighting • One-tap copy for messages and code blocks • Model selection and instant switching • Image and file attachments (vision-model dependent) • Token usage tracking per message • Thinking and reasoning model support • Voice input for hands-free prompting • Chat history with local storage • Optional API key authentication

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 message content used for model training • No analytics on conversation content • API keys encrypted and stored locally • Open connection — you see exactly where your data goes

Who Airgap is for • 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

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 Mac mini, 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.
