  LinguaLayer - Learn Languages While You Browse
  
  Turn every webpage into a language lesson. LinguaLayer replaces common English words with their Japanese, Spanish, or French equivalents as you read naturally.
  
  HOW IT WORKS
  - Words on every page you visit are subtly swapped to your target language
  - Substituted words appear in blue with a dotted underline
  - Hover over any word to see the original English, translation, and pronunciation
  - Adjust the intensity slider to control how many words get replaced
  
  FEATURES
  - Three languages: Japanese, Spanish, and French with 500+ word dictionaries each
  - Adjustable word intensity from 5% to 20% (up to 50% with Pro)
  - Smart substitution that skips code blocks, input fields, and scripts
  - Hover tooltips showing English original, translation, and romaji/pronunciation
  - Works on every website automatically
  - Toggle on/off with one click from the popup
  
  WHY IT WORKS
  Research shows that contextual learning - encountering new words in familiar settings - dramatically improves vocabulary retention. Instead of dedicated study sessions, you absorb new words while reading articles, browsing social media, or checking email.
  
  LANGUAGES
  - Japanese: 590+ high-frequency words with romaji pronunciation
  - Spanish: 540+ common words
  - French: 640+ common words
  
  Pro upgrade unlocks higher intensity settings (up to 50% word replacement) and Korean language support. One-time purchase, no subscription.
