Download YouTube video captions/subtitles

Users cannot easily download YouTube subtitles in a usable format for research, note-taking, or learning purposes

1. Install extension. 2. Open a YouTube video page. 3. Click extension icon or use the injected download button. 4. Select output format (JSON or TXT). 5. Caption file is downloaded to the browser's download folder.

Target users: Students / Researchers / Content creators / Anyone who wants to save YouTube subtitles for offline use

The extension only works on YouTube watch pages (content_scripts match https://www.youtube.com/watch**). It does not handle YouTube Shorts or other YouTube URL patterns. The analysis is based on static code inspection; runtime behavior on actual YouTube pages was not tested.

Monetization

No paid features detected

The extension is entirely free with no paywalls, subscription prompts, or billing integrations. The keyword 'pro' found in the static analysis was a false positive from the _metadata/verified_contents.json file (a Chrome Web Store integrity manifest) and a minified variable name in scripting.js, neither of which relates to paid features.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login UI, nor does it call any authentication or account APIs. The core workflow (downloading YouTube captions) relies entirely on YouTube's built-in CC feature, which works for public videos without requiring the user to log in to the extension or YouTube. While a YouTube account is needed to access some private or member-only content, the extension itself does not require login to function for standard public videos.
