AI 产品解读YouTube bilingual (dual) subtitle display - simultaneously shows subtitles in two languages on YouTube videos with customizable styles
Language learners watching YouTube videos need to see subtitles in both their native language and the target language simultaneously, but YouTube only supports showing one subtitle track at a time
User installs extension, navigates to any YouTube video with available subtitles. The extension injects a content script that fetches translated subtitles and displays both the original and translated subtitles simultaneously on screen. Settings (style, language, mode) are accessible directly from the subtitle area on the video player.

- 目标用户
- Language learners watching YouTube content / Users who want to understand videos in foreign languages / Multilingual YouTube viewers
- The content.js file is a large minified bundle (422KB) making line-by-line analysis difficult, but all grep searches across all files confirmed no login/payment logic exists
- The 'token' keyword hits in content.js are from CSS/markdown parsing libraries (not authentication tokens)
付费分析未识别到付费功能
No evidence of paid features. Grep for premium, subscription, payment (real), stripe, billing, purchase, license, upgrade, donate, paywall, and unlock all returned zero meaningful matches. The 'pro' keyword hits are all false positives from non-English localized text (e.g., 'problèmes' in French, 'problemen' in Dutch) where 'pro' is a substring of the word 'problem'. The extension provides all its features (dual subtitles, style customization, font/size/color/spacing settings) without any gating or upgrade prompts.

- No login, account, sign-in, sign-up, register, or authentication keywords found anywhere in the 145 text files. The extension operates entirely locally via chrome.storage.sync/local for settings. It injects content scripts into YouTube pages and modifies subtitle display without requiring any authentication to an external service or extension account.
太棒了!很好用!
Finalmente achei o que eu precisava!!! Precisava assistir uma série que não tinha um dos episódios traduzido, apenas em russo no youtube e não achava como traduzir de jeito nenhum. Com essa extensão consegui usar e entender a legenda tranquilamente. Parabéns aos desenvolvedores, ficou ótimo!!!
YYDS
its great but i noticed that for chinese videos that already have subtitles in both engligh and chinese, that the option available to click the default available chinese subtitles is not there. It is mahcines translating the engligh subtitles into chinese but i want the chinese sutibtitles in the video. Its probably because in the default languages listed to choose, you have Chinese listed as Chinese (simplified) and Chinese (traditional) and the chinese video has its manually translated sutbtitles listed as Chinese (chinese). See the link of the video i am refering https://www.youtube.com/watch?v=LUl2X99y6KM
これで英語のYouTubeビデオを見れました。
有没有计划,加入 ChatGPT哈,自己设置APIKEY
الإضافة تؤخر الترجمة مع وقت ظهورها، محتاجها تظبيط من جديد.
매번 자막 선택하래서 짜증났는데 이게 해답이네요
双字幕优先使用视频字幕有些问题,有些视频已有的中文字幕还不如自动翻译出来的质量好,这时候没办法把双字幕切换成优先使用自动翻译。如果“字幕”选择了从英语自动翻译到中文,“默认字幕”选择英语,这时候又只显示中文不显示英语了。如果能切换优先使用视频字幕还是优先使用自动翻译就更好了
This is the best extension for learning a language. I can finally run two captions at once. It works perfectly and integrates itself into the YouTube UI so well that you'd think it was build by YouTube themselves.
