Make music together — four people, one video. Record a 30-second clip in one box of a 2×2 grid; anyone can fill an empty box with their own clip until all four play in sync, like a single video.
Start a jam by recording into one box. Your post appears with three empty boxes. Other people pick an empty box, record along to what's already there (they see and hear the existing clips), and publish. When all four boxes are filled, the post plays as one synced video in the feed.
GapJam is a place to sing, play an instrument, or just join in. You control your own clips, can hide them from your profile, and decide who you interact with — with reporting and blocking built in.
