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.
The latest update is great. But the length of the caption is short. Can you change the length to can be changed?
Không biết có thể quay về phiên bản cũ hay không, đơn giản dễ dùng và chất lượng. Phụ đề mới quá nhiều dòng, khiến mình phải nhìn qua lại giữa hai phụ đề rất khó khăn ! Mình mong rằng phiên bản mới sẽ sớm fix hết các lỗi liên quan đến trải nghiệm người dùng.
字幕位置只能固定 不能随着荧幕切换大小自动修正位置 每次都要手动挪
怎么突然不能下载字幕了?这个功能非常实用啊啊啊 希望作者大大尽快加回来吧
新版能不能把字幕下载功能保留回来,同时添加一些单词单个翻译和生词本收藏功能,或许开通一下付费功能也是可以接受的
这更新的是个啥,全屏竖屏小窗居然不会自然自动缩放吸附,只会在固定的地方。全屏和小窗我都要挪位置呗?调颜色大小藏的深也就算了不容易找到外,现在就连最简单字幕功能都做不好。这么反人类的更新是怎么做出来的?
Can't export subtitles any more, bad update.
新版没有原版好用了,有时候字幕过长都没办法打开选项栏
一下子我的字幕下载选择栏没有了,不能字幕下载了。结果重新删除并安装后依然没有改变。
新版是有毛病怎么的?字幕随便拖动,在全屏状态拖到下面中间的位置,缩小之后直接字幕都不见了,还得重新拖回来,合着每次都要自己拖动?这个字幕的位置是固定的,不会跟着视频全屏或者缩小变化相对位置和大小。还不如以前直接固定呢。
