AI 产品解读Download subtitles from YouTube, Netflix, and NPO Start video pages
Language learners need access to subtitle text from streaming videos to look up words and study foreign languages, but streaming platforms don't provide easy subtitle download options
1. User navigates to a video on Netflix, YouTube, or NPO Start. 2. Extension content scripts intercept platform's internal JSON data to extract subtitle track information. 3. User clicks the extension popup and presses 'Get available subtitles'. 4. Extension queries the content script for available subtitle tracks. 5. Available subtitle languages are displayed in a dropdown. 6. User selects a language and clicks 'Download' to save the subtitle file.

- Language learners studying foreign languages / Users who want to extract subtitle text from streaming video content
- No YouTube worker.js file present in package despite being referenced in manifest web_accessible_resources - may indicate incomplete packaging or the YouTube feature uses a different approach (direct page scraping via content script)
- No source code for npo.js appears to be used by any entry point in the current manifest (it's not referenced in content_scripts), suggesting it may be legacy code
- Cannot fully verify whether the extension works without being logged into Netflix/NPO Start since the subtitle interception depends on those platforms' internal APIs being active
付费分析未识别到付费功能
The extension itself has no paid features, premium tiers, subscription gates, or billing integration. All keyword hits for 'paid' terms are false positives: 'pro' in netflix/worker.js refers to Netflix subtitle profiles (data.params.profiles), 'license' in jquery.min.js is the jQuery MIT license header. No payment platforms, upgrade prompts, or feature gates found in the source code.

- The extension itself has no login mechanism, but it operates on Netflix (requires paid subscription/account), NPO Start (may require account), and YouTube (free). For the Netflix subtitle extraction feature to work, the user must be logged into Netflix with an active subscription. The extension intercepts Netflix's internal JSON API responses, which only occur when a logged-in user is watching content.
