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.
Very good extension! The new update is a bit difficult to understand at first, but i really like the personalisation aspect. I struggle with dyslexia and having both subtitles so close in the same font/color made it a bit harder for me to check for words i don't know at a quick glance. Now, I can have it distinct from one another! And it's good to have it removed from the actual youtube subtitles bar because I kept having to fiddle with it with different videos and getting confused. Thank you so much for making this free!
It was a flawless extension, but with the latest update, subtitles are overflowing off the screen, and the settings interface has been made more complicated. I hope it gets fixed as soon as possible.
업데이트 후 약간의 불편함이 생겼지만- 늘 감사히 쓰고 있습니다. ☺️ 낮은 평점 리뷰에 마음 쓰지 마시고 화이팅 부탁드립니다!🙂
更新后打开十个视频里至少七八个是根本不出字幕的,字幕开关按钮没有任何作用。 目前解决办法只有点开若干视频后,运气好哪个开始出字幕了再回退回想看的那个视频去才能用。 关闭拓展程序、刷新、卸载重装都没用。这是目前最大的问题。 字幕位置也不跟随视频了而是固定显示器位置, 全屏时把字幕拉到中下了、换网页小窗看还要再把字幕拉回视频里去,不然等于是字幕就在网页底下。 之前记得还带视频清晰度锁定功能?现在也没有了。 总体上更新后体验极差,出字幕与否还要roll点儿的感觉,到了基本不能用的地步。 设置方面也不是很清楚,出字幕后点左上角那小点才能改, 所以那么多人问诸如字体字号怎么调、中文原文上下位置怎么改吧。
Bad UI
真的非常遗憾。对我最有用的一个功能:字幕下载,更新后没有了.........(.哭的很大声
Its broken now. Subtitles default on every time
Why delete download subtitles function and seems cancel dual substitle at the same time?! hah
更新后找不到设置的方法.现在只有广告会出现字幕.而且只有英文字幕.不是双字幕.仅剩的功能就是拖动字幕位置.希望可以让我回到之前的版本.
我使用最新版chrome瀏覽器,發現介面除了可改字幕位置、按shift會顯示字幕範圍外,其他的功能都失效了。
