Built GhostDance — overlay any TikTok dance as a ghost on your camera to practice in real time.
Been learning dance moves from TikTok but hated the pause/rewind loop on my phone. So I built a web app that overlays the original dancer as a translucent ghost directly on your camera feed.
Upload any video → ghost appears → you follow → record yourself → export. No install, works on mobile browser.
Feedback will be much appreciated!
