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.
Works well but not on all videos. I ensured that subtitles are available, but it still only shows in native language rather than target language, when both are desired as "dual". Anyone got a fix for this? Thx in advance!
改更新了,大佬,不能用了.
denedim ve çalışmıyor. Ben Türkçe altyazı falan göremedim. Görenler acaba neyi gördü?
непрацює уже і удаляла його і скидувала настройки нет просто не показує субтитри мгновенних субтитри у мене виключени незнаю що робити
Holy geez. What a genius work.
因为没有在选项中出现单字幕的条目还以为不能用了,但在https://www.youtube.com/account_playback的字幕设定中开启“总是显示字幕”和“包含自动生成字幕(若有)”两个选项之后,再回到视频,便又可以正常工作了,供参考。
中文繁體不能顯示
现在是用不了了吗
能更新一下吗?字幕不准,不实时,有时还显示今天不能使用翻译
