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.
不错
最近更新后开单字幕会没字幕显示
字幕下载怎么加载不出来了???
so great
最好用的软件。
“双字幕下载”这个非常好!"zhuwei"不能用后终于找到这个可替代的工具,而且还更方便,谢谢你们奉献! 使用问题:还是需要把“单字幕”打开,设置“默认字幕”为中文...再设置回自动和关单字幕
用过最好的双字幕插件
这个插件非常好用,我几乎所有字幕插件都试过,就这个最完美,感谢制作者!(那些打差评的人是真的没良心啊)。 但有一个问题,经常会出现字幕所有选项突然全部消失的问题,刷新或改设置都没用,每次都只能重新移除再安装才行(不过相对它的好用,这只是一个小问题)。

确实很nice,很实用:-)
