Overview

免費網頁雙語對照:原文一行、譯文一行。支援任何網頁(Alt+A)、X、Reddit 與 YouTube 雙語字幕。預設免費引擎、免 API 金鑰,繁簡中文皆可。

把任何外文內容變成「原文一行、中文一行」的對照閱讀,幫你更快讀懂、順便學語言。 ■ 主要功能 任何網頁:點工具列圖示 →「翻譯這個網頁」,或按 Alt+A,一鍵整頁雙語;再操作一次即關閉。採用通用版面偵測,連 Facebook 等以 div/span 排版的現代網站也能抓到內文。 X / Twitter、Reddit:開啟後自動雙語顯示,只翻譯你捲到的內容,速度快、不浪費額度;按 Alt+A(或按鈕)可隨時隱藏/顯示翻譯、切回原文。 YouTube:影片字幕雙語對照,像電影字幕一樣一句一句跟著聲音,中文在上、英文在下(可調整);按 Alt+A 可切回原本字幕。 雙擊單字浮窗(選用,預設關閉):在任何網頁雙擊單字或反白詞句,就地浮出原文+🔊 朗讀、翻譯,單字還附字典卡。此功能開啟時才會請求「在所有網站執行」權限,關閉即一併撤除。 繁體/簡體中文一鍵切換。 多種譯文樣式:底線、框線、醒目提示、斜體、粗體,以及「學習模式」(中文先模糊,滑過才顯示,逼自己先看原文)。 可自訂譯文顏色與字體大小。 ■ 翻譯引擎 Google 翻譯(預設、免費、免金鑰):速度快,零設定即用。 Gemini(譯文更自然,需自填免費 API key):用 AI 翻譯,語氣和專有名詞處理更好;預設 gemini-3.5-flash-lite。 ■ 隱私 不追蹤、不投放廣告、不販售資料。 設定與 API key 保存在瀏覽器的 Chrome 設定中;若開啟 Chrome 同步,會隨你的 Google 帳號同步到其他裝置。 只有在你觸發翻譯時,才會把該段文字送到你選擇的翻譯服務。 讓讀外文像讀母語一樣輕鬆。 Bilingual Reader turns any foreign-language content into easy line-by-line reading — original on one line, Chinese on the next — so you read faster and pick up the language along the way. ■ Features Any webpage: click the toolbar icon → "Translate this page", or press Alt+A — full-page bilingual; do it again to turn off. A general layout detector finds the real body text even on modern sites built with div/span (e.g. Facebook). X / Twitter & Reddit: automatic bilingual display, translating only what you scroll to — fast and quota-friendly; press Alt+A (or the button) to hide/show the translation anytime. YouTube: clean, movie-style bilingual subtitles synced to the audio, one sentence at a time, Chinese on top (adjustable); press Alt+A to switch back to the original captions. Double-click word popup (optional, off by default): double-click a word or select a phrase on any page to get the original + 🔊 read-aloud + translation in place, with a dictionary card for single words. This feature requests broad host access only when you turn it on, and gives it back when you turn it off. One-click Traditional / Simplified Chinese. Multiple translation styles: underline, box, highlight, italic, bold, plus a "learning mode" that blurs the translation until you hover. Customizable translation color and font size. ■ Engines Google Translate (default, free, no key): fast, zero setup. Gemini (more natural translations, requires your free API key): AI translation with better tone and proper-noun handling; defaults to gemini-3.5-flash-lite. ■ Privacy No tracking, no ads, no data selling. Settings and API keys are stored in your browser's Chrome settings; if Chrome sync is on, they follow your Google account to other devices. Text is only sent to your chosen translation service when you trigger a translation.
