# Fast. Secure. Private.

Bring your own API keys and chat with frontier AI like ChatGPT, Claude, Gemini, and more.

Open source. Requires a desktop Chromium-based browser such as Chrome, Edge, or Brave.

Open AirmailAI on a desktop Chromium-based browser to try the demo or start chatting.

## Why AirmailAI?

### Privacy by design

Your chats and keys travel directly from your browser to your provider. Conversations never touch AirmailAI servers.

### Providers and tools

AirmailAI supports OpenAI, Anthropic, Google, and OpenRouter APIs all in one chat UI. Upload files and search the web.

### Pay as you go

You only pay providers for the tokens you actually use. AirmailAI adds zero markup.
