okay this is hackernews and there are tons of similar sites to videocyborg ... so can you tell us what's so special about yours ? thanks

It doesn't constrain you to a specific set of website. For example you are interested in a video from the New york times website (the last one posted for example is : https://www.nytimes.com/video/world/europe/100000004602800/i...). you can put this link into https://videocyborg.com and it will download it.
