AI 产品解读Enhances Amazon Prime Video with language learning tools: adds multilingual subtitles, mouseover dictionaries (79 languages), word-click links to dictionary sites, Google Translate integration, playback speed controls, and video display adjustments.
Language learners watching foreign content on Amazon Prime Video lack built-in tools to look up words, see subtitles in their learning language, or easily translate phrases. This extension bridges that gap by adding subtitle overlays and instant dictionary/translation features directly on the video player.
1. Install extension and set native/learning language + Amazon region on install page. 2. Navigate to any Amazon Prime Video content page. 3. Extension adds a subtitle enable button on the video detail page. 4. Click the button to activate the subtitle viewer. 5. Extension loads subtitles (from Amazon's built-in tracks or searches OpenSubtitles.com for external subtitle files). 6. While watching, hover over words for instant dictionary popups; click words to open external dictionary sites. 7. Use keyboard shortcuts for subtitle navigation, playback speed, and quick replay.

- 目标用户
- Language learners who watch movies, TV shows, and anime on Amazon Prime Video / Users studying Japanese, Spanish, English, Chinese, Korean, Arabic, Hindi, Thai, French, German, and other languages / Users who want dictionary and translation tools integrated into their video watching experience
- Source files are heavily minified (contents-min.js at 187KB), making line-level analysis more difficult but key patterns were still identifiable
- Cannot verify runtime behavior of OpenSubtitles API rate limiting and login prompt trigger without testing on actual Prime Video pages
- The extension bundles large dictionary files (100+ MB total) which were not inspected for content, only the loading logic was verified
