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.
I've used it on 4 different computers, its never worked, I don't understand where all the good reviews come from. I just want to use the features where the subs come line by line instead of word by word, and the custom size / colour etc

道理我都懂,你锁视频清晰度是怎么回事?
非常好用,個人建議個人化的顏色可以多增加固定的功能,這樣顏色能一套一套的換,不用去記色票顏色 最近翻譯字幕都顯示不出來,會在一開始的時候全部顯示 另外因為中文的選項有各種括號,希望能多增加一些選擇,不然讓他自動判斷繁體簡體會判斷到哪個括號的不一定
Ahora se ha convertido en una app INDISPENSABLE, maravillosa, pone los substitulos en el idioma deseado de forma automatica, pone ambos idiomas para los que están aprendiendo o mejorando otro idioma, se puede personalizar la fuente para una facil lectura y la mejor parte de todas (por si no bastaba ya) es que carga los subtitulos previamente (y no los genera mediante el video se va reproduciendo) aparte están siempre centrados y con el mismo tamaño, esta app es indudablemente la mejor.
This thing attempts to google translates the sub of first language to spit out the sub of second language. This results in utter garbage lines. Do not use.
能不能固定字幕位置,每次暂停字母都会浮动很烦人
非常好用 ! Great app for youtube Firefox 版 https://addons.mozilla.org/zh-TW/firefox/addon/youtube-dual-subtitles/
