About SubShield – Subtitle Blocker
SubShield – The Ultimate Language Learning Companion
Are you trying to learn a new language by watching videos, but find your eyes constantly glued to the subtitles? SubShield is here to help!
SubShield is a lightweight, powerful extension designed specifically for language learners. It forces you to rely on your ears by elegantly blocking video subtitles, helping you dramatically improve your listening comprehension and language immersion. Whether the subtitles are soft (CC) or hard-coded (burned into the video), SubShield's customizable blackout boxes have you covered.
Why install SubShield? If you want to truly master a language, reading translation subtitles will hold you back. SubShield creates an immersive listening environment on any video platform. And don't worry—if you ever get stuck and can't catch a word, a simple keyboard shortcut lets you take a quick peek!
Core Features:
🎯 Two Blocking Modes:
Bottom Bar Mode: Instantly covers the standard subtitle area at the bottom of the video. You can easily adjust the height and position.
Custom Box Mode: Deal with hard-coded or unusually placed subtitles by drawing your own custom blur boxes directly on the screen!
👁️ Quick Reveal (Sneak Peek): Couldn't catch that last sentence? Just press shortcut (or use Click/Hover triggers) to temporarily reveal the subtitles for a few seconds.
🎨 Multiple Shield Styles: Choose from elegant Blur (glassmorphism), Solid Black, or Semi-transparent styles to match your viewing preference without ruining the video aesthetics.
⚡ Universal Compatibility: Works seamlessly on YouTube, Bilibili, Netflix, and virtually any website that uses HTML5 video players.
🌙 Modern UI: Features a beautifully designed popup menu with native Dark Mode support.
Stop reading and start listening. Install SubShield today and take your language skills to the next level!
