What is bob-plugin-openai-translator?

This is a plugin for Bob, a macOS application used for text translation and OCR. The plugin connects Bob to OpenAI's language models so that translations and text improvements go through AI rather than a traditional translation service. It supports three main functions: translating text between languages, polishing writing to make it more natural, and correcting grammar. The polishing feature works by setting the target language to the same as the source language. When you highlight a sentence and trigger the plugin, it rewrites the text for clarity and style rather than translating it. The README describes this as a replacement for grammar tools like Grammarly, and notes it works for any language, not just English. A separate companion plugin focused only on polishing with more advanced rewriting options is also mentioned. Setup requires installing Bob version 0.50 or higher on a Mac, then downloading the plugin file, and finally adding an API key from OpenAI. The key goes into the plugin's settings within Bob. The README also mentions an optional integration with a Mac tool called PopClip, which lets a small icon appear near selected text so you can trigger translation without switching windows. The README is written primarily in Chinese, with a link to an English version of the documentation. A related browser extension for non-Mac users that performs similar translation is also mentioned separately. The project is open source and accepts contributions through a guide in the repository.
