Auto Translator

Auto Translator is a Chrome extension that translates visible web-page paragraphs into Korean. Translation runs through a local native bridge that reuses the local Codex CLI’s ChatGPT login — no external API keys involved.

The extension connects to the local host via Chrome Native Messaging, keeping one native messaging port open during a translation session so batches reuse the same host process. The host starts codex app-server per session and keeps it alive through an idle timeout, so consecutive page translations skip the cold start.

Since Chrome extensions cannot install native messaging hosts themselves, a one-click macOS companion installer (Codex Translator Installer.app) ships alongside. The installer reports each step as it runs — copying the runtime, registering the native host, opening the extension setup page — and on failure shows the failed step with a recovery hint.
