Usually, if 3-4 people want to watch a YouTube video together they would either sit around the same computer or try to start/stop the video at the same time so they can chat in between. The first option is often impractical to do and the latter one creates a lot of confusion due to the lack of synchronization.
SynchTube solves this problem by letting you watch YouTube with friends in a synchronized way. Each video watching session creates a separate chat room and the person who creates the chat room is usually the person controlling every thing. When other people join the session, the leader can start the video and can also see where everyone’s video is at any point in time.
When the leader stops/pauses the video, it is stopped/paused for all the people in the session. Every session gets a unique link that can be used to invite friends. To load a video, the leader simply needs to enter the URL of any YouTube video.

Features:
- Watch YouTube videos with your friends.
- Chat with friends while watching the video.
- Everyone watches the same thing in a synchronized way.
- Change the video being watched.
- No registration required.
