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.
Me ha funcionado!
请问一下,下载字幕后导入原视频,字幕一直是初始字幕模式,不可以是自定义后的字幕吗?
为什么不能用了
Love the work
字幕的字号太大了(笔记本上观看),希望能加入调节字体大小的功能,或者开发者能把默认字号调小些,特别能提升使用体验,给4星是因为字号大小问题。
为什么突然变成单字幕了,两个选项改了几次都不行。只能光看中/英,第二个字幕不见了只出现了默认字幕,但是插件还在,选项也在,只是不显示了。
非常好用!可以增加选中单词弹出翻译和生词本功能吗?
超级好!!帮大忙了!谢谢作者💕💕💕
Very useful.
Very useful. However, I have a suggestion: can't you make it possible to have the second text not be translated by a computer, but show the one already provided by the video itself? Sometimes, there are videos whose authors have already made themselves two different subtitles, so it would also be very useful if we could play those two at the same time instead of only one and the second one always being translated by a computer.
