Beam

Beam is a native ChatGPT app for macOS that allows users to access ChatGPT across any application, website, or document instantly. It eliminates context switching by providing a floating chat panel that can be opened with a hotkey. Beam offers features like templates, personas, macros, and the ability to chat with PDF documents. It is a one-time purchase with lifetime access, no subscription fees, and no logins, using the user's own API key.
