Watch and listen together, from different houses

Same video, same second

Counting down "three, two, one, press play" over a call never quite lands, and it falls apart the moment someone pauses. Butter My Jam keeps playback state — playing, paused, position, volume — in sync in real time across every device in the room, so everyone is on the same moment without coordinating by voice.

Anyone in the room (or only the host, if you chose "Host controls") can pause, skip, or seek, and the change propagates to everybody else.

Good for

• Long-distance listening. Share an album or a set of tracks with someone in another city.
• Music video marathons. Everybody adds picks to one queue instead of taking turns screen-sharing.
• Study and work sessions. A shared background playlist that anyone in the group can steer.
• Remote watch parties. Line up a queue of videos and let it roll while you chat on your usual call app.

How to set one up

1. One person creates a room and becomes the host.
2. Send everyone the room link or the six-character room code.
3. Each person opens it in their browser and picks a nickname.
4. Add videos by search, by pasting a YouTube link, or by pasting a whole playlist.

Voice chat is not built in — keep your usual call running alongside it. Desktop guests see the synced video; mobile guests see the synced timeline and full queue controls.

What each person sees

Everyone in the room shares the same queue and the same playback position, but the view adapts to the device. On a desktop or laptop, guests get the synced video player alongside the queue. On a phone, guests get the synced timeline, the current track, and full queue controls without the video eating the screen.

Mute and volume are room-wide controls, so changing them affects everyone's player at once. If you are all in separate homes, that is usually what you want. If several of you are in the same physical room, turn down your own device or system volume instead and let the host's speakers carry the audio — otherwise you get an echo.

Keeping the room yours

Make the room private with a password if you are sharing the link in a group chat, and use Host controls if you would rather guests queue videos without being able to skip what is playing.
