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.
This extension is completely broken now, Subtitles flow out of the video window, majority of the times it won't even show dual subtitles, just use "Interactive Dual Subs for Languages Learning" extension, its way better.
谷歌浏览器今天用不了,edge浏览器能用,奇葩
Vou dar uma estrela apenas porque parou de funcionar após a nova atualização. Como um desenvolvendo de sites entendi que o simples sempre agrada a maioria. Veja, os usuários não estão preocupados com a UI bonita ou com funcionalidades que fogem do foco principal, que e ter as legendas duplas, vocês deveriam criar uma extensão separada com essas outras funcionalidades e manter essa com a versão antiga, que funcionava como deveria e tinha o básico para mudar a cor, simples e funcional.

Можно ли как-то менять размер одного из языков субтитров?

中文字幕在開頭就整坨擠滿螢幕,根本不能當雙字幕使用==
字幕配音?
陪伴了我很长时间的扩展,用不了的朋友可以去下个“沉浸式翻译”这个扩展,也有双语字幕,还能很方便地翻译网页
翻譯的字幕都在前面一開始全部炸出來,不懂為什麼這樣設計-_-
