Want to share only part of a YouTube?

Then you want Vibby.  This video service allows you to select a YouTube video, edit the part you want.  You can also add a text comment (and your viewers can respond). You can watch just the highlights or the entire video. While there are other products that allow you to do the same (Zaption, EDPuzzle) but with Vibby, you can just share the url or embed the clip.  There is no need for a student account or login.
