WatchSync

About

WatchSync lets you watch videos together with synced playback on most web pages that support HTML5 video. Create a room from the page you are already watching, share a room code or invite link, and keep play, pause, seek, resync, and playback speed aligned in near real time across participants.

Install WatchSync if you want an easy way to stay in sync with friends, a partner, classmates, or teammates without relying on screen sharing, countdowns, or constant “pause there” messages. It makes remote watching feel smoother, more natural, and much closer to watching together in the same room.

WatchSync works across many video sites and supports pages with multiple videos by letting you choose the correct one manually. It is great for watch parties, long-distance couples, study sessions, recorded lectures, product demos, training videos, and remote team collaboration.

The extension is designed to be simple and fast: open the page, create or join a room, and start watching together. WatchSync stores your settings locally in Chrome and uses live room and playback data only to keep participants synchronized.
