Language Anki by ParallelSub

Display dual subtitles on YouTube using native translation

Master languages while watching YouTube — no account or cloud required. http://www.youtube.com/watch?v=FtQ-U1kEjlw Want to study with YouTube but feel lost without subtitles in your own language? Language Anki by ParallelSub shows the original and translated subtitles together, saves the words you don't know, and helps you review them at the right time. Everything stays in your browser. 🌟 Key Features 1. Smart Dual Subtitles • Shows the original and translated subtitles together whenever the video has subtitles. • Switch the translation language from the right-click menu — Japanese, Korean, Chinese, Spanish, French, Vietnamese, Indonesian, Thai, Hindi and more. • Adjust font, size, colors, line count and position. 2. One-Click Word List (W-LIST) • Encounter an unfamiliar word? Just click it in the subtitles — it is instantly saved to your W-LIST. • The full sentence where the word appeared and its translation are saved automatically. • Works on any web page too — double-click a word to see its translation in a popup, then click the word to save it. You can also select text and use "Add to W-LIST" in the right-click menu. 3. Review with Video Sync • See the word's meaning and its context sentence at a glance. • Jump to Video: go straight back to the exact moment in the YouTube video where the word appeared. • Listen to the pronunciation with your browser's text-to-speech voices. • Look the word up in Google Translate, DeepL, Weblio or your own dictionary URL. 4. Built-in "Anki" Spaced Repetition • Mark each word as "Remembered" or "Don't know", and the next review is scheduled at the most effective time for your memory. • Review the context by playing the video segment, test your recall, and master vocabulary with your ears, eyes and voice. • Organize words into multiple lists, sort them, and export or import your lists as a JSON file. 🔒 Private by Design • No sign-up or login. • Your word lists and settings are stored only in your browser. There is no developer server, and nothing is uploaded to us. • The only network connections are to YouTube (to load subtitles) and Google Translate (to translate the words and sentences you add). Dictionary and search pages open only when you click them. 🌍 Menus in 52 languages, following your browser's language. 🚀 How to Get Started 1. Click "Add to Chrome". 2. Open any YouTube video with subtitles. 3. Start learning — the dual subtitles appear automatically. Language Anki by ParallelSub is completely free. Turn YouTube into your personal language academy!
