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.
Супер вариант. Как раз то что нужно для изучения языков.
Não está aparecendo as legendas duplas
之前沒問題,最近變成error 429.雙語模式下,要麼就是只有原字幕、翻譯行顯示error 429,要麼沒字幕。
subtitle not poppin on screen. Never.
dejo de funcionar!!! error 429
Hello, yesterday I was using the YouTube plugin to subtitle a programming course, and now I came to watch the rest of the tutorial. It seems like the plugin is not working and a red message appears that says: Error 429: An unexpected error occurred.
great
В общем в начале года сразу после того как пропала возможность выделять и копировать текст я написал об этом поставив 5 звёзд с надеждой на то что это исправят в будущем, но увы спустя пол года ничего не поменялось текст всё ещё нельзя выделять так как это было до 2025 года поэтому видимо придётся искать другое похожее расширение. Хотя в расширении указано "Улучшения в версии 3.7.3" - "Улучшенное копирование текста и поиск слов"
詐騙軟體,開了反而沒字幕,連原本字幕都不會顯示了,爛爆!
funcionou para o bug de só legenda em inglês do YouTube
