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.
所有設置都沒反應
用了很多年,当初在知乎看到的,我实在太爱了,昨天第一次申请了visa卡,捐赠了好几个喜欢的开发者或者视频创作者之类的,但是去看了官网没找到捐赠链接,所以特地来咨询一下!
希望能够增加翻译字幕朗读功能。
This implementation is working great. Translated captions appear side by side and can be highlighted to copy and paste easily. The downloaded subtitles allows you to download any language, and bilingual subtitles as well into a single spaced text file or srt file. You can switch easily back to regular captions right from the settings wheel within the player. All properties of the CC font can be changed but the setting pane is lacking a preview.
非常好用,感谢作者
自动翻译服务中断,请稍后重试。 自动翻译出现暂时性故障,可能在几分钟后恢复。
很牛的插件 感谢作者。不过 目前用下来只能显示英文字母 有人知道在看英文视频的时候如何显示中文字幕吗?
感谢作者大大,一直在用的插件,也推荐了很多朋友使用。 有个需求,作者是否能考虑增加对shorts视频的支持呢?
非常好用的插件,但是请求作者制作一个Safari版本。我一直被迫使用chrome仅仅因为这个插件,Safari在此功能上缺少同类插件。
Con unas cuantas opciones más sería perfecta. Le falta un lector con voz para que nos lea los subtítulos, y la posibilidad de visualizar todo el texto del video de una.
