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.
