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.
失效了
Estou usando a 'dual-subtitles.com' para estudar inglês com vídeos no YouTube, e até o momento ela está me ajudando muito. Parabéns pelo trabalho de vocês, é uma extensão muito útil. :D
好用,相見恨晚!
Great Addon, One thing I would change is an option where you can make every word in a different color, so that the words in the subtitles match each other, So when you have dual subtitles you know exactly which word is which. everything else is perfect.
不错,感谢作者!
Nice plug-in, BUT some settings is missing. A separate font LARGE for: -default mode -cinema mode -full screen mode
good ~!!!
Hiç yorum yazmam normalde ama bu eklenti aranılan eklenti elinize sağlık.
That is just awesome!
Great work! If possible, I hope to add two functions for learning purpose: 1. When a word is selected or the mouse is hovering over the subtitles, the video can automatically pause. 2. Add three shortcut keys for browsing subtitles. For example, pressing the keyboard letter ‘A’ will jump to the previous subtitle, ‘D’ will jump to the next subtitle, and ‘S’ will repeat the current subtitle. I also found a problem, when the subtitle is original subtitle without translated subtitle, the custom style and copy subtitle function does not work, for example, when the video only has automatically recognised English subtitle, and the default translated subtitle is also in English, the subtitle style and copy function does not work. I would like to be able to customise the style and copy subtitles when the subtitles are only original subtitles without translation. (Update: I found a tweak, adjust Font Size of Translate subtitles to 0, it'll only show the Video subtitles with custom style.) edit: The custom style and copy subtitle functions don't work with some YouTube movies. Thank you very much!
