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)

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.

疑问:有些视频有(英文)cc字幕,插件就会自动选择cc字幕翻译,而不是自动生成的。然后字幕就会有很大的延迟(可能是cc字幕本身就有延迟,时轴偏差)。碰到此类视频都得手动选成自动生成的,有什么办法让插件只翻译显示自动生成的字幕吗
你好作者,提供这么好用的插件,我在看一个视频视频特别长,有8个小时,到了3小时的时候,后面就不翻译了,这是为什么呢,希望得到回复。再次感谢
我觉得很棒!
Очень много настроек, сделать все под себя не составляет проблем. И профили, кстати, сохраняются, можно не боясь экспериментировать, всегда можно откатиться к предыдущему профилю. Маленький совет: чтобы открыть окно настроек, нужно нажать левой кнопкой мыши по значку расширения.
Thank you, exactly what I was after!
This is the best language learning subtitle extension. It automatically saves your preferences for both the native language and target language, unlike other extensions. THANK YOU!!! Will be glad to support this!
请问一下这个英文的字母怎么翻译都是大写的呀,能改成想官方自动翻译那样的吗
这是github上面同名的项目吗
你好!我想请问这个如何调整字幕的字号大小?按设置-字幕-选项-字号将字号调整为50%,但界面字号还是同原来一样并没有改变呀!
