A Duet is a TikTok feature that lets you record a video that plays side by side with someone else's. Both clips run at the same time, so viewers see the original and your reaction, addition or performance together.
People use Duets to react, harmonize with a song, answer a question, play along with a challenge or show a side-by-side comparison. Creators control whether others can Duet their videos in their privacy settings.
For brands, Duets are a low-effort way to join a conversation and show personality. They also work in reverse: inviting your audience to Duet a video can spark user-generated content and boost reach.
Questions about Duet
What is the difference between a Duet and a Stitch on TikTok?
A Duet plays your video next to the original at the same time. A Stitch clips a short part of the original video and then plays your video after it. Duets suit reactions and play-alongs, while Stitches suit replies and commentary.
Why can't I Duet a TikTok video?
The creator may have turned Duets off, or the account may be private. Some content types, like certain licensed audio or ads, can also block Duets. Check the share menu; if the option is missing or grayed out, it isn't allowed.
Do Duets help you grow on TikTok?
They can. Duetting a popular video puts your content next to something people already like, and the original creator's audience may discover you. Adding real value, like humor or expertise, matters more than just reacting.
