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 funciona perfecto, se le podrian incorporar mas funciones para posicionar bien donde deseas que salga el subtitulo, y poder moverlo y ajustarlo ya que muchas veces se salen de la pantalla en la vista normal, poder delimitar cuanta cantidad de lineas deseas mostrar
2026.2.26 字幕插件完全用不了啦!!!!! 赶紧修复吧哥们 更新:更新后字幕全屏窗口和默认窗口会错位,每次都需要手动调整字幕,用了好几年了,国内英语不好的靠这个字幕在油管学了太多电子音乐制作相关的技术和 知识!
YouTube Dual Subtitles is one of my favorite extensions for learning languages! I am surprised that this is not built into YouTube to (1) enable people from different cultures to watch at the same time, (2) to learn languages, (3) and to watch productions in the original language and in a language the viewer understands, which really adds to the feeling. Great work with this app!!! I would love to donate to support your work. Thank you.
能把字幕翻译的连续性解决一下就更好了
very nice!!!!
之前很好用,不過目前英譯繁中的中文字幕會在一開始就全部跳出來,希望可以改善一下
最近发现很明显的法语识别成西语,还改不了,不知道是不是新的问题。然后有时候会出错翻译不了,其他大部分时候还是很正常的,不知道其他语言怎么样

好虽好,但如果能支持移动网页端就更好了。手机看桌面端的网页很麻烦。
