One is a macOS menu bar agent designed to streamline communication with AI coding agents like Codex, Claude Code, and terminal agents. Every question an agent asks lands in a single unified inbox, allowing developers to answer in a keystroke without hunting for the right window. One intelligently triages and routes responses to the appropriate agent automatically. It supports both voice and text input, giving users a Siri-style experience directly on their Mac. Privacy is a core principle: voice, screen, and terminal data go only to the model and never to any server-side archive. One is free to use and requires only a ChatGPT account to get started.
