scam. asks you to download a companion app for it to work. when you do that it puts a giant ass watermark in the corner of the video. only way to get rid of it? buy a $25 "conversion license" fuck off. if i cared about licensing, i wouldnt be downloading yt videos against their TOS. there's plenty of free addons to use for this that dont take a million years to set up just to give you nothing.
