A duet puts your video side by side with someone else's original, both playing at once. It's TikTok's built-in reaction and collaboration format, and one of the cheapest legitimate ways to put your face in front of someone else's audience.
Pick a video, tap share, choose duet, and record your half. The result shows the original on one side and you on the other, credited and linked to the source.
Creators can turn duets off per video or account-wide, and the credit chain stays visible. Reactions, harmonies, judge-the-outfit games and split-screen challenges all grew from this one button.
A duet inherits some of the original's momentum: viewers of a trending video get offered reactions to it, and the For You page tests your take in front of an audience already interested in the topic.
For a small account, that's borrowed distribution with no budget: the trend supplies the audience, your angle supplies the reason to follow. It converts best when your half genuinely adds something: expertise, a joke, a correction.
The creator turned duets off for that video or their whole account. Nothing is wrong with your account.
They're tested by the same system. A good duet can outperform your normal videos because it enters with the trend's audience attached.
A duet plays side by side at the same time. A stitch plays a clip of the original first, then cuts to you. Duet is simultaneous, stitch is sequential.
