AirmailAI

AirmailAI is an open-source, browser-hosted chat application that connects your browser directly to AI providers using your own API keys (BYOK). It aggregates multiple provider APIs — OpenAI, Anthropic, Google, and OpenRouter — into a single chat UI and emphasizes privacy by ensuring chats and keys travel directly from the browser to the provider without touching AirmailAI servers. The app runs in a desktop Chromium-based browser and offers an in-browser demo and immediate usage without server-side storage or markup on provider usage.

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