Stream Vocab mode lets you read each book phrase, with meanings and readings attached directly to each word, with optional voice narration.

Japanese Vocabulary Maker helps you understand difficult Japanese text, research unfamiliar words, and build vocabulary lists, all from any Japanese content in seconds. Choose your input method:
  • URL: paste any Japanese webpage or a direct link to a PDF file
  • Image (OCR): upload a photo of a book page, manga panel, or any printed Japanese text
  • Paste Text: paste Japanese text directly to analyze it
  • File: upload an EPUB ebook, plain text file (.txt), subtitle file (.srt / .vtt), or audio file (.mp3, .m4a, .ogg, .wav, .flac)
  • Audio URL: paste a link to a podcast episode or audio file for automatic transcription and instant vocabulary lists
  • YouTube: paste a YouTube link to build a vocab list from its captions and stream it in sync with the video: each word highlights as it's spoken, with adjustable playback speed (great for listening practice and shadowing)
  • Anime Subs: search an anime by title to pull its Japanese subtitles from Jimaku and build a vocab list from the dialogue, or upload your own subtitle file (.srt / .ass / .vtt)
For every word you get its hiragana reading, romaji, part of speech, and definition, making it easy to research words you don't know and go through even the most difficult text with confidence. Each entry links to Jisho and lets you jump back to the word's context in the original text. Classical Japanese is supported: historical kana (ゐ, ゑ) and Aozora Bunko texts are handled correctly, with original characters shown in context.

Use Stream Vocab to step through the content phrase by phrase with synchronized audio playback, which is great for deep reading or listening comprehension practice.

When you're done, export your list to Anki or Quizlet, or take a quick 20-question quiz to reinforce what you learned. Perfect for building targeted JLPT study lists at any level (N5–N1).

Record a video of the pages of a book while flipping through them. For best results:

  • Hold each page steady for at least a second or two.
  • Use bright, even lighting.
  • Show pages in order (1, 2, 3, etc).
  • Make sure page numbers are visible.
  • Fit each page cleanly into the frame.
  • Make sure pages are as flat as possible.
  • Speak each page number out loud (while holding it still) to improve quality, and say just "page" if there is no page number.
  • Sample book video scan

Note: stream the scanned pages to go through a sentence at a time, with meanings for vocabulary words shown.
