  FINNISH STREAMING DUAL SUBTITLES — Learn Finnish Through YLE Areena & Ruutu.fi 🇫🇮
  
  Master Finnish naturally by watching YLE Areena & Ruutu.fi with dual subtitles. See Finnish and your target language side-by-side in real-time, turning every video into an immersive language learning experience. 📺✨
  
  Check the extension landing page: https://finnish-streaming-dual-sub.netlify.app/
  
  YLE Areena website: https://areena.yle.fi/tv
  Ruutu website: https://www.ruutu.fi
  
  
  WHY THIS EXTENSION? 🤔
  
  Learning Finnish is challenging — spoken Finnish differs drastically from written Finnish, with unique grammar and slang. 😤 Traditional study methods don't prepare you for real conversations. 📚❌ This extension bridges that gap by letting you learn through authentic Finnish media: news, dramas, documentaries, and more. 🎬🎯
  
  
  KEY FEATURES ⭐
  
  ✓ Dual Subtitle Display — See Finnish + translated subtitles simultaneously 📝
  ✓ Multiple Language Support — Translate to English, Vietnamese, Japanese, Spanish, or any of 30+ languages supported by DeepL 🌍
  ✓ High-Quality Translation — Powered by DeepL, known for accurate and natural translations 🎯
  ✓ Smart Caching — Translations stored locally for 30 days, rewatching uses zero API calls 💾
  ✓ Multi-Token Support — Add up to 2 DeepL API tokens with visual usage tracking 🔑
  ✓ One-Click Toggle — Enable/disable dual subs directly in the video player 🎛️
  ✓ Shadowing Tools — Rewind/forward 3 seconds buttons + keyboard shortcuts (, and . keys) for pronunciation practice 🔄⏱️
  ✓ Blur Mode — Hide Finnish, translation, or both subtitles to test yourself — hover to reveal 💪💪
  ✓ Word Lookup — Select any word in a subtitle and right-click for an instant in-page translation without leaving the video 🔍
  ✓ Copy Subtitle — Click the copy icon to send the current Finnish subtitle line to your clipboard 📋
  ✓ Reload Subtitles — Clear cached translations for the current episode and re-translate from scratch if anything looks off 🔄
  ✓ Privacy-First — All data stays in your browser. Zero tracking. 🔒
  
  
  HOW TO USE 🚀
  
  Install the extension and add your free DeepL API token in settings ⚙️
  (Optional) Select your preferred translation language from the dropdown (default is English) 🌐

  Click the "Dual Sub" toggle in the player 🎛️
  Start learning Finnish through immersion! 🌟
  
  
  ℹ️ SETTING UP YOUR TRANSLATION KEY (ONE-TIME, 5-10 MINUTES)
  
  📖 What is a translation key (API key)?
  
  A translation key is like a password that allows this extension to use DeepL's translation service. It's completely free for basic usage!
  
  ⚠️ Important: You'll need a credit card to sign up for DeepL's API, but the free tier is 100% free - you won't be charged unless you choose to upgrade to a paid plan.
  
  🤔 Why do I need to set this up?
  You might wonder: "Other dual-sub extensions like Language Reactor, Trancy, and InterSub work instantly—why not this one?"
  Here's the truth: Free services either use low-quality translation APIs, run at a loss (subsidized by premium users), or monetize your data.
  💰 I built this extension differently because I believe you deserve:
  
  - ✨ Best-in-class translations – DeepL provides high-quality translations to 30+ languages including English, Vietnamese, Japanese, and more
  - 🔒 Complete privacy – No data collection, no ads, no tracking
  - ♻️ Sustainability – No active maintenance burden on my end
  - 🆓 Truly free – DeepL offers a free tier to get you started
  
  Yes, it takes 5-10 minutes for one-time setup, but you get premium quality without compromise. Worth it? I think so! 😊
  
  🔑 How to get your free translation key:
  
  📺 Video walkthrough (recommended): Watch 1 min tutorial on YouTube: https://www.youtube.com/watch?v=VgpxUH7SbSY

  ℹ️ SETTING UP YOUR TRANSLATION KEY (ONE-TIME, 5-10 MINUTES)
  
  📖 What is a translation key (API key)?
  
  A translation key is like a password that allows this extension to use DeepL's translation service. It's completely free for basic usage!
  
  ⚠️ Important: You'll need a credit card to sign up for DeepL's API, but the free tier is 100% free - you won't be charged unless you choose to upgrade to a paid plan.
  
  🤔 Why do I need to set this up?
  You might wonder: "Other dual-sub extensions like Language Reactor, Trancy, and InterSub work instantly—why not this one?"
  Here's the truth: Free services either use low-quality translation APIs, run at a loss (subsidized by premium users), or monetize your data.
  💰 I built this extension differently because I believe you deserve:
  
  - ✨ Best-in-class translations – DeepL provides high-quality translations to 30+ languages including English, Vietnamese, Japanese, and more
  - 🔒 Complete privacy – No data collection, no ads, no tracking
  - ♻️ Sustainability – No active maintenance burden on my end
  - 🆓 Truly free – DeepL's free tier gives you 500,000 characters/month!
  
  Yes, it takes 5-10 minutes for one-time setup, but you get premium quality without compromise. Worth it? I think so! 😊
  
  🔑 How to get your free translation key:
