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.
您好,最近两天使用下载字幕功能,选择字幕列表一直在转圈无法加载,换了很多有字幕的视频重试、重新安装重试、重启电脑、刷新网页等操作都做了几遍,可是依然无法再次使用下载功能,这个能修复吗?
Это невероятно, спасибо большое!
请问,双字幕可以正常显示,但是字幕没办法下载,点开下载选项,一直转圈圈
Пользуюсь уже давно и вот при просмотре очередного видео появилась мысль "как же хорошо иметь двойные сабы". Спасибо большое разработчикам
字幕無法下載 一直loading
繁体中文不需要翻译,现在繁体中文也会显示两种字幕。
除了油管是否可以移植到任意的在线视频?
1. 点击“字幕下载”菜单,字幕消失; 2. 点击“字幕下载”,仅“English (auto-generated)”可用,其它语言不可用; 3. 建议将“默认字幕”菜单更改为“第二字幕”
👍👍👍👍👍👍
I've been having some problems with the dual subtitle itself. It doesn't activate two languages when I click on the button, for example in the same video that I used to see both subtitles in English and Portuguese, now it only shows the English subtitle. I don't know if it's a bug, or if there's anyone having the same trouble, but it's frustrating.
