Visitors to the website begin an online chat (audio and video) with another visitor. At any point, either user may leave the current chat by initiating another random connection. Chatroulette is a free online video chat website that allows users to meet strangers worldwide. The site was created by Andrey Ternovskiy, a 17-year-old high-school student in Moscow, Russia, who wrote the first version of Chatroulette in "two days and two nights".

To use Chatroulette, you need a computer with a working webcam, the latest version of Flash installed, and working speakers. If you want to talk, make sure your microphone is working, as well. The site is moderated by state-of-the-art AI technologies and humans to ensure safety.
