iWatchUWatch

iWatchUWatch is a Chrome extension that lets two people watch the same video in sync on separate computers, regardless of the site it's hosted on. One person creates a room and shares an 8-character code; once the other joins, both sides start playback together after a countdown. The extension continuously monitors drift between the two viewers, nudging playback speed or seeking to keep them aligned, and pauses both sides together if one buffers. It works with Netflix and any other page containing video. A 7-day free trial is offered with no card required.
