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.
Last update made so worse! I used to be able to select text (to research) which was one of my favorite things about this extension, now it's no longer possible, very sad!
잘 쓰고 있습니다. 혹시 화면 상의 자막에서 바로 드래그하여 복사하는 기능은 넣을 수 없나요? 모르는 단어 찾을 때 드래그하고 싶습니다.
Fantastic, thank you for making this.
Lo estoy usando para ver unos cursos de programación en ingles y prefiero leer en ingles, pero es bueno tener el subtitulo en español a la mano para no perder la idea, asi que esta funcion es genial porque me permite ver los dos idiomas a la vez incluso puedo poner el tamaño mas grande al subtitulo original para no distraerme y solo ver en español cuando no entienda algo muy bien! muchas gracias!
Opa. Estou testando, e está muito bom. Pode ria talvez separar milímitro(s) entre as duas legendas, Minha opinião, talvez seja melhor compreendido e visual será melhor... Porquê esta opinião. Estou usando audio de um idioma e as duas legendas em outros dois idiomas... Baseado neste exemplo, notei que será, ao meu ver, de uma melhor visualização... Outra: Seria poder encurtar a legenda, e ou, poder escolher menos palavras para poder centraliza-lás.. Uma visão apenas. Se não dá, ok. se der. Pense sobre.. Grato Parabéns pela extensão.
Brilliant, very creative. It helps me a lot to study French on YouTube. Thank you!
화질 고정 옵션은 삭제됐나요? 자물쇠 아이콘이 안보이네요
Вообще отличная вещь, только можно было бы сделать регулировку по ширине, а то длинные в столбик выстраиваются
新版唯一的缺点就是把字幕下载去除了,请恢复字幕下载吧
thank you, really helpful
