Tracking since May 9, 2026.

  description

  LinguaLens turns the streaming you already do into language practice.
  
  Every subtitle on Netflix, YouTube, Prime Video, Max (HBO), and Disney+ becomes interactive: click a word you don't know, get a contextual translation in your native language, save it, and come back to review with mini-games — not boring flashcards.
  
  ━━━ How it works ━━━
  
  While watching:
  • Dual subtitles (target + native language) side by side.
  • Click any word — popup shows its translation, the meaning in this scene (not just the dictionary's first guess), pronunciation, and optional Anthropic Claude AI commentary on slang, sarcasm, or cultural references.
  • Hyphenated words and contractions ("brother-in-law", "I'll") are handled correctly. Shift-click selects multi-word phrases ("look forward to").
  • Pause on hover, auto-pause at sentence end, hide-translation-until-hover for active recall.
  
  While reviewing:
  • 7 review modes, all auto-game-ified — no boring 4-button flashcard:
     ◦ Due review (SuperMemo-2 spaced repetition)
     ◦ Stuck on (leech detection)
     ◦ Quiz (multi-choice fill-in-the-blank)
     ◦ Match (6-pair pairing game)
     ◦ Type (typing recall)
     ◦ Listen (TTS-first quiz)
     ◦ Reverse (recall the source word from the translation)
  • Daily streak counter, 30-day activity heatmap, editable daily goal.
  • Sound + speech feedback: chime on correct, soft buzz on wrong, every word read aloud after pick.
  
  ━━━ What makes it different ━━━
  
  • 5 streaming platforms supported out of the box — most extensions cover 1 or 2.
  • Multi-source dictionary: Google Translate baseline + 270+ idiom dictionary + Urban Dictionary slang fallback + optional Anthropic Claude contextual reading.
  • Contextual sense matching: "toast" in a wedding scene becomes "raise a glass", not "bread".
  • Behavior-based subtitle detection: works even on platforms (Disney+, HBO Max) that ship subtitles through obscure rendering paths instead of standard <track> elements.
  • Subtitle delay slider (±2 seconds) for platforms that occasionally ship out-of-sync captions.
  • Anki TSV export for power users.
  • 7 UI languages out of the box (English, Turkish, Spanish, Portuguese, French, German, Japanese), auto-detected from your browser.
  
  ━━━ Privacy ━━━
  
  LinguaLens has no servers of its own. All saved words and settings stay in your browser via chrome.storage. Translation requests go directly to Google Translate and (optionally) Anthropic — only the word you click + the surrounding sentence. Nothing is sent to a LinguaLens-controlled server because there isn't one.
  
  ━━━ Optional AI ━━━
  
  Bring your own Anthropic API key for Claude-powered contextual reading of sarcasm, idioms, and cultural references. Off by default. Direct API access from your browser — billing on your own Anthropic account, never on us.
  
  ━━━ Open source ━━━
