About

VocaSub: Dual Subtitles & Real-Time Translator for YouTube
VocaSub is a powerful browser extension that enhances your YouTube experience by providing real-time, dual-language subtitles. Designed for language learners, international students, and global content enthusiasts, it helps you understand and learn languages naturally as you watch your favorite videos.

Main Features
1. Bilingual Subtitle Display
View original captions and high-quality translations simultaneously. Seeing both languages side-by-side helps you map vocabulary and grammar structures in context, making it an ideal tool for language immersion.

2. Seamless Real-Time Translation
VocaSub uses high-performance technology to provide translations that are perfectly synced with the video's audio and original timestamps. Experience smooth, lag-free translation as the video plays.

3. Customizable Visual Experience
Tailor the subtitle interface to your preference:

Premium Aesthetics: Modern design with glassmorphism effects.
Font Control: Choose professional fonts and adjust text size for maximum readability.
Visual Styling: Customize text colors, background opacity, and panel positioning.
4. Interactive Sidebar Mode
Switch to the sidebar view to see subtitles as a scrollable list. This is perfect for reviewing previous lines of dialogue without interrupting the video flow.

5. Privacy and Performance
Ultra-Lightweight: Minimal impact on browser performance.
Privacy Focused: No tracking, no data collection. All settings are stored locally on your device.
How to Use
