  YouTube Transcript Sync adds a focused transcript side panel to YouTube videos. Open a video, click the extension, and read the available captions beside the player without leaving the page.
  
  The transcript follows playback, highlights the current caption segment, and lets you click a timestamped line to jump to that moment in the video. You can show or hide timestamps, switch between available caption tracks, and use YouTube's available auto-translation languages when they are provided for the video.
  
  For note-taking workflows, the side panel can send the transcript text to an open Notion page, or open Notion when no tab is available. Pro users can copy transcripts, copy raw JSON, and download transcript data as `.txt` or `.json` from the options page.
  
  Key features:
  
  - Read YouTube captions in a browser side panel
  - Sync the transcript with video playback
  - Click transcript lines to seek the video
  - Toggle timestamps on or off
  - Switch between available original caption languages
  - Use YouTube auto-translation options when available
  - Send transcript text to Notion
  - Pro export tools for `.txt`, `.json`, and clipboard workflows
  
  Notes:
  
  - Transcripts depend on caption tracks available from the current YouTube video.
  - Auto-translation depends on YouTube's available translation options for that video.
  - Export and copy actions require Pro activation in the extension options page.
