Highlight text and translate, summarize, expand, polish, or auto-complete it without leaving the page, using your own OpenAI API key. ## 定价与套餐 Free to install. You need your own OpenAI API key, and you pay OpenAI directly for the tokens you consume; the extension itself does not charge a subscription. ## 关键功能与能力 - **In-page translation:** Detects the language of your selected text and translates it into your chosen primary or secondary language without leaving the page. - **Text completion and expansion:** Select text or use a hotkey to have GPT expand associations and finish or elaborate on your sentence, with Tab-key acceptance for speed. - **Summarization:** Condenses a selected block of text into its key points so you can grasp the main ideas at a glance. - **Polishing and grammar fixes:** Refines grammar, sentence structure, and readability so the result reads professionally. - **Local API key storage:** Your OpenAI API key is kept in the browser's local storage, so credentials are not sent to a third-party server. ## 主要用例 - **Summarize dense reading (Students and researchers):** Highlight a long article or paper paragraph and instantly pull out the key points instead of re-reading it several times. - **Translate on the fly (Multilingual professionals):** Read foreign-language pages and translate selected passages into your working language without switching to a separate tool. - **Draft and polish emails (Writers and knowledge workers):** Expand a short bullet into a full sentence or clean up grammar in a draft before you send it. ## 优势 - Works on any web page without leaving the current tab - Covers translation, summarization, expansion, and polishing in one small extension - API key stays in local browser storage, not on the developer's servers - Lightweight install (about 112 KB) with declared no data collection ## 局限 - Requires your own OpenAI API key and separate OpenAI billing - Very early version (0.0.1) with no ratings and a small user base - Only English and Simplified Chinese are listed as supported UI languages - Interface is minimal, with no team, history, or sync features ## 常见问题 ### Do I need my own OpenAI API key?
