Language Reactor is a browser extension and web application meticulously crafted to enhance the acquisition of foreign languages through engaging videos and texts. It is predominantly employed with platforms such as YouTube and Netflix, enabling users to immerse themselves in content enriched with bilingual subtitles and instantaneous prompts.

How it operates:

  • Bilingual Subtitles: Simultaneously presents the original text alongside its translation.

  • Click on a Word/Phrase: Offers immediate translations, definitions, and occasionally contextual usage examples; users can curate entries for their personal vocabulary repository.

  • Viewing Control: Incorporates auto-pause after dialogue, phrase repetition, adjustable playback speed, subtitle navigation, and customizable hotkeys.

  • Transcript: Provides the complete text of subtitles with advanced search and filtering functionalities.

  • Vocabulary Management: Facilitates the saving of words, training exercises, and the exportation of lists (for instance, in CSV/Anki format).

  • Reading Mode: In the web application, users can peruse texts with highlighted vocabulary and translations.

  • Bilingual Subtitles: Displays both the original text and its translation simultaneously; users can toggle the order of lines or conceal the translation until hovered over.

  • Auto-Pause and Repeat: Halts after each utterance, allows for the repetition of the current line/segment, and enables quick rewinding to the previous utterance.

  • Subtitle Navigation: Constructs a list of utterances with search capabilities; users can jump to any phrase with a single click; filters (for example, utterances containing “new” words).

  • Click on a Word/Phrase: Provides instant translation, part of speech, and variations of meaning; allows saving in a vocabulary list with context and timestamp.

  • Speed Control: Adjusts playback speed, enables precise rewinding, and loops problematic phrases.

  • Vocabulary Highlighting: Rare words are emphasized; displays an approximate percentage of “unknown” words in the video.

  • Writing Support: For Japanese — furigana, for Chinese — pinyin (can be toggled on/off).

  • Customization: Subtitle size/font, dark theme, panel positioning, and compact mode.

  • Hotkeys: Navigation through utterances, repetition, auto-pause; keys can be customized.

Words, Phrases, Training

  • Vocabulary Preservation: Words/phrases, translations, contextual examples, and links to moments in the video are saved in “flashcards.”
  • Organization: Tags, notes, designations of “known/learning,” and thematic lists.
  • Training: The web application features review exercises (flashcard format, active recall).
  • Export/Import: Allows exporting lists in CSV/TSV (for Anki, etc.); importing personal lists of “known” words to hide their highlighting.
  • Statistics: Tracks progress in the language, counts of new/known words, and user activity.

Reading Mode (Web Application)

  • Text Reading: Users can input text or import subtitles — receiving click-translation, highlighting of rare words, and a dictionary panel.
  • Search and Filters: Locate sentences containing specific words/grammatical forms, and practice “problematic” areas.
  • Saving/Training: Offers the same flashcard capabilities as in videos.

Translations and Dictionaries

  • Sources: Original platform subtitles + machine translation when a secondary track is unavailable.
  • Settings: Selection of translation language, display style (constant, on click, hide until hovered).
  • External Dictionaries: Quick links for in-depth analysis (definitions, examples, pronunciation).

Pro vs Free Version

  • Free: Bilingual subtitles, auto-pause/repeat, click translations, basic word saving.
  • Pro: Enhanced limits on saving, advanced filters/training/export options, additional display and translation settings.

Compatibility (Briefly)

  • YouTube: The most comprehensive feature set on PC (Chrome/Edge).
  • Netflix: Bilingual subtitles, navigation, auto-pause, word cards; occasionally requires an extension update following interface changes on Netflix.
  • Web Application: Reading mode, vocabulary work, training, export capabilities.
