Two links, So I'll post a message:
Chrome Extension: http://goo.gl/rhwid5 Website: https://youtulong.com
Basically, it runs a simple skip to timeframe script with youtube API, thus TL;DW's videos without actually editing video.
By using the chrome extension (shows and runs TL;DW's made for the video you are watching on youtube), the users remain in youtube website, so no traffic gets stolen.
For more advanced features, use the website.
