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.

很好用,就是有的时候可能会出错
字幕背景无法透明了
シンプルでよくできている。 しかしバグがあります。動画をフルスクリーンにした時に、翻訳語の字幕の大きさを設定できません。 翻訳後の字幕だけが常に巨大なフォントで描画されてしまい、動画が視にくくなります。 このバグが修正されることを願いします。 This plugin is simple and well made. However, there is a glitch. When the video is set to full screen, the size of the subtitles for the translated language cannot be set. Only the translated subtitles are always rendered in a huge font, making the video difficult to view. I hope this bug will be fixed.
为什么我有的时候能下载翻译的字幕,有时无法下载呢,时好时坏
doesn't work anymore, pls fix
讚啦
