Openai Translator

Openai Translator is a browser based translation app that uses OpenAI language models to translate text between languages. It is built as a progressive web app, so it can be installed on a phone or desktop and used like a native application. The interface is available in English, Simplified Chinese, Traditional Chinese and Japanese. The app supports a very long list of source and target languages, including automatic source detection, and lets the user choose a translation style before running a job: general and precise, academic, technical, business formal, everyday spoken, or literary. This makes it useful for people who need translations that match a register rather than a literal word for word result. It works on a bring your own key basis. The user enters an OpenAI API key and, optionally, a custom API URL in the settings. The site states that the key is stored only in the local browser and is never sent to a server. Settings also cover streaming output with a typing effect, the model to use (the list includes gpt 4o mini, gpt 4o, o1, o3 mini and several newer GPT and open weight options) and a temperature control from precise to creative. A history view keeps earlier translations. The app itself is free and publishes no paid plans. Usage costs are whatever the user's own OpenAI account or compatible endpoint charges.
