React, Collaborate, or Just Play Along
Duets let you sit right next to someone else's video without ever meeting them β reacting to a joke, harmonizing with a singer, or adding a punchline turns a solo clip into a shared moment, and it's one of the easiest ways to join a trend already in motion.
It Also Works as a Response Tool
Beyond entertainment, creators use Duets to answer questions, add commentary, or extend a tutorial someone else started, which is why the feature has become as much a conversation format as a creative one.
Frequently Asked Questions
Can I duet with any video?
No β the "Duet" option only appears if the person who posted the original video has allowed duets on it.
Can I change the screen layout?
Yes β from the recording screen you can choose a side-by-side or top-and-bottom layout, whichever fits your video better.
