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.
there is a problem please can you fix it , this what i got when i turn the sub , this is what shows up ,[ json parse error unexpected end of json input ]
Cromban egyáltalán nem működik mostanában. Pedig nagyon szerettem!!!! W-11
Раньше работало, сейчас- нет. Очень жаль, отличное было дополнение
我的之前用的好好地,最近这几天一直显示“JSON Parsing Error: Unexpected end of JSON input”同时还无法使用转换成其他语言翻译。请尽快修复
今天使用时,失效了,怎么调试都没用,请检查更新
бл так сложно обновить что-ли
2025 Ahora ya ni siquiera funciona y bloque los sub de YouTube si la tienes instalada, no aparecerá ningún subtitulo. 2024 esta extension era maravillosa en su version 3.67 pero desde que la cambiaron la interfaz es horrible y poco intuitiva ahora muchas veces falla y quitaron la mejor función que tenia que era la descarga de subtítulos. 2022 La mejor que he probado jamás, puedes configurar automáticamente para que un video que no tiene sub en tu idioma traduzca los que existen a tu idioma sin que tengas que hacer nada de manera automática siempre que habrás un video subtitulado,.
super ! Thank you so much ! It will help me to learn ukrainian
是已经失效了吗?
