Stay on the same frame—even when you're miles apart. You each stream from your own account; Duet only carries the timing.
How it works
Duet works with what you already watch. Your video never passes through us.
Each person streams from their own account in Chrome. Duet never copies or relays the movie.
Use two laptops, a laptop and TV, or two TVs with the companion controls.
Play, pause, seek, and countdown cues keep both sides together down to a fraction of a second.

Duet never copies, relays, or re-streams video. Both people need their own access to what they are watching.
