What is it?

OpenAI Translator is a progressive web app that sends translation requests to any OpenAI-compatible chat model through the /v1/chat/completions API. Users set a custom API base URL and API key, then pick a suggested model or type in any chat model identifier the provider supports.

The app can stream output as it is generated and saves translation history in the browser. Because it is a PWA, it can be installed on phones and desktops. It is built with React 19, Vite, Tailwind CSS with DaisyUI, and React Query, and can be deployed as static files or as a Docker container served by nginx.
