Master Japanese with EPUB Books

Welcome to the Japanese Reader Playground! This reader uses active recall and interactive parsing to turn standard EPUB novels into customizable language learning exercises.

📖 Key Features & Mechanics

Active Recall Reading

Unread sentences in your EPUB books are blurred out by default, allowing you to focus on one sentence at a time.

  • Focused Practice: Click a blurred sentence to open the practicing board.
  • Interactive Game: Solve by dragging and dropping tokens into the blank slots, or type your answer directly in the input box.
  • Next Unread Highlight: The next sentence is underlined with a blue dashed border and a pulsing indicator so you never lose your spot.
  • Splitting Paragraphs: Large paragraphs or quotations can be split into smaller, manageable sentences using the "Break paragraph into sentences" button.
  • Yomitan Integration: The reader's layout and interactive board are fully compatible with the Yomitan popup dictionary browser extension, allowing instant word lookups and vocabulary study.
