Screening Room is a watch party that actually feels like being in the same room. Send one link, everyone takes a seat, and the film starts on a shared countdown so every screen hits the same frame. Play, pause, or skip and it happens for the whole group. You react live, chat, and pin comments to the exact moment they happen. And the Usher, an AI host running on our own cheap GPU, runs the room: it welcomes people by name, calls them out when it goes quiet, runs hot-take polls, and can pause or jump the whole group on request. Anyone can host it for pennies, and it drops onto any video page with one bookmark.

Playback needs to stay in sync across everyone in the group — someone plays, pauses, or skips, and it should reflect for the whole group, not just them. On top of sync, give the group a way to react together as it happens — live chat, emoji reactions, comments tied to a moment in the video/audio, whatever makes it feel like you are watching or listening together instead of alone. This is about a shared, synced experience for a group, not a single-user media player. Build it and have something published for use in 20 minutes
