🎨 What Does NBJ Condenser Do?

AI-Powered Condensation
NBJ Condenser uses AI to intelligently condense YouTube videos:
  • Extracts the script from the video using speech recognition
  • Analyzes and condenses the content using Claude AI (aggressiveness: 5/10)
  • Generates new audio with natural text-to-speech voice
  • Creates a slideshow using key frames from the original video
  • Produces a final video that can be between 75% and just 10% the length of the original video

It can also produce a super-compact "key takeaways" page or audio file

💡 Best for: Educational videos, tutorials, documentaries, podcasts, and long-form content. Perfect for when you want the key information without watching the entire video!

❓ Troubleshooting

"Not a YouTube video page"

Make sure you're on a youtube.com/watch?v=... page
The extension only works on actual video pages, not the homepage, search results, or channel pages

"Connection error"

The server may be offline or unreachable
Contact your administrator to ensure the server is running

"Server is busy"

Another video is currently being processed
Wait a few minutes and try again when the current job finishes

"Processing failed"

Some videos can't be downloaded (age-restricted, private, removed)
Try a different video - standard public YouTube videos work best

Extension didn't install

Try the alternative manual installation method (see Step 2 for details)
Make sure you're using Chrome or Edge (other browsers may not be compatible)
Check that the ZIP file downloaded completely (should be 14 KB)
