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.
好用!
好用,平时上的时候要看翻译每次都要自己选一次,中文还在最下边,很烦,感谢老哥搞的插件
Прекрасное приложение, это то что я так давно искал, 5 звезд безоговорочно, простая реализация без лишнего и все суперско работает
nice!
자동으로 한국어로 번역되고 동영상을 재생할 때마다 한국어 자막이 고정으로 자동 번역 돼서 너무 좋네요! 또한 원본 자막 없이 번역된 자막만 볼 수 있어서 언어 공부하는데도 많은 도움이 됩니다! So nice App!!! Thanks for made this!
so nice!!!
用过来最简单友好的双字幕软件了(小白狂喜
我使用默认的英文 chrome, 插件有 bug. 这个插件中, 在视频上右键菜单, single subtitle需要先打开, 然后再去调节 default subtile为中文, 最后再关闭 single subtitle 才能实现中英双语字幕. 这种 bug, 多数情况下, 换个网络环境和电脑应该就可以检测出来, 但是不是稳定情况, 现在无从知晓. 最后必须感谢作者开发的工具, 虽然有其他的youtube 字幕插件可以使用, 但是你这个美工好呀, 而且多了个选择, 谢谢作者. 期待不断完善. 另外,版本做得相对稳定了, 建议开个捐赠.
无效
真心受用,感谢开发者!
