You record yourself dancing. You watch it back. Something feels off — but you can’t tell where to start fixing it. ChoreoSync helps you line up your practice video with the original choreography, then gives you an AI score out of 100 so it’s easier to see where your timing, position, or movement starts to drift. No more guessing. No more scrubbing back and forth trying to figure it out. Check your score, spot the difference, and focus on what to fix. AI DANCE SCORE Compare your movements to the original and get a score out of 100, broken down into Pose and Sharpness so you can quickly see where the gap is. SEE WHAT TO FIX ChoreoSync helps you spot the moments where the difference becomes more noticeable, with a side-by-side skeleton overlay, the body part that needs attention, and clearer feedback to guide your next correction. AUTO SYNC IN 2 SECONDS Align your practice video with the original in one tap. No manual adjustment and no dragging through the timeline — so you can start comparing timing, movement, and formation changes faster.
