WatchWithMe allows you to watch videos in sync on separate computers.

Step One:

To start a room, paste any valid YouTube url into the box on the homepage.
This makes you the controller of the room. That means you control when the video starts, stops, and pauses -- and you can seek to any position in the video you want.

Step Two:

Share the link to your room.
This invites people to join you and watch the video in sync. No matter what you do with your video, their players will sync up with yours -- perfect for long-distance relationships, remote viewing parties, or just fun with friends.

Step Three:

Enter your chat handle to start talking.
The chat box on the right-hand side of the page allows you to discuss the video with anyone else in the room, without having to interrupt your video by pulling up your preferred chat client.
