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.
一直是非常棒的插件,但最近翻譯自動產生的英文出現錯誤,希望能修復
translation does not work, only English works, other languages do not...

Doesn't work properly. UPD: It seems to be working already, thanks
最近這些天又突然沒能正常顯示譯文字幕了,請修復
After testing, I took the developer's word that this is indeed a youtube issue, if this extension is using a youtube translation source, When youtube engineers are doing backend upgrades or bug clearing, then we will not be able to use double subtitles for a while, I changed to a maximum of Rating. THANK YOU SO MUCH for the free extension!
为什么最近突然不能显示双语了?甚至只显示中文翻译也做不到,请尽快更新吧
It used to work very well in Turkish, but nowadays it doesn't work at all.
请教一个问题,很喜欢原来初始的绿色字幕式样,不知道改了什么设置,再也改不回原来的样式,自定义式样,重置式样试了都没用,都变成大白字了。还是喜欢原来的初始式样,怎么改回去哈,请教!
