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.
Works like a charm, best extension to learn another language with youtube!!

一直跳不出翻譯後的字幕....
I seriously don't understand why this has so many positive reviews. I want it to work so bad that I've tried at least 20 times, on different pcs and laptops, mac and windows, in the past 2 years. It doesn't work, the subtitles just disappear sometimes and you're left with the default youtube ones. Often the language is stuck in english too and can't be switched without it disappearing, for no reason.
Simplesmente incrível.
试用一下还是挺好的,这个只能用于字幕翻译,之前我一直用可可翻译,可以字幕翻译和网页翻译。
Game CHANGER, would recommend 10/10
إضافة جيدة للترجمة الفورية لمقاطع الفيديو على يوتيوب .. لكن في بعض الأحيان تظهر رسالة بأن الترجمة غير مفعلة لوجود مشكلة ما مع الإحاطة بأن الرسالة لا توضح نوع المشكلة .. بعد بحث وتجربة وجد ان حل المشكلة هي محو جميع الهيستوري والكوكيز على المتصفح .. الإضافة تحتاج لمزيد من التطوير .
下載不了字幕,麻煩改bug
it really helps~
