As well as announcing the bi-weekly contest categories via the platform with presenter Will Best, Cowell has urged contestants to use Skype to rehearse with one another.
"Skype is a valuable partner for The You Generation," Cowell said.
"Practising with your friends is the best way for you to improve your skills and Skype can offer invaluable ways for you to perfect your performance."
Skype has also offered contestants hints and tips for filming their auditions via its Big Blog and Rehearse subdomain.
"You have to get ready to get noticed; to make sure your performance really shines, hone your talents by rehearsing with your friends on a Skype video call," said Angie Hill on The Big Blog.
"Receiving live advice from your friends and family as if they were the judges themselves is the perfect way to make sure your audition is as strong as it can be. "
