How do I add the iPhone Kupi sound so it lines up?

Updated: October 27, 2026

Short answer

Our video follows the AI clip by @thecocovex, which starts the trending sound at 0 seconds. Open that clip in TikTok, tap its sound, choose Use this sound and keep it starting at 0 seconds: the unfold, the dance and the toss line up. The song itself is not in our video.

How to add the sound

Download your video, or the silent version, from My videos.
Open the @thecocovex clip in TikTok, tap the sound name and choose Use this sound.
Upload your video and keep the sound starting at 0 seconds.
Turn the video’s own audio down to 0 if you want only the original sound.

Why the sound is not included

Songs on TikTok belong to their owners. Our video carries a new AI-made instrumental dance beat with no words, and you add the sound you want inside TikTok, where it is licensed.

How to add the original sound in TikTok

Our videos come with an AI-made original soundtrack. To use the trending sound instead, add it inside TikTok when you post: that also puts your video on the sound's page, where people following the trend look. You can also download a silent version from My videos and put the original sound on that.

Open this clip in TikTok: our video follows it. Tap the sound name at the bottom, then tap Use this sound.
Tap Upload and pick the video you downloaded from us.
Open Volume and turn the video's own sound down to 0, or download the silent version from My videos.
To line up the beat, use the scissors (trim) to start the sound from 0 seconds, then post.
