What is Air Drawing?
Air Drawing is a free browser-based drawing experiment that lets you draw without touching the screen. Your webcam watches for a hand, and the tool tracks the position of your index fingertip. As you move your finger, the Canvas API turns that movement into a digital stroke.
How the finger tracking works
This tool uses MediaPipe Hand Landmarker to identify hand landmarks in the camera image. The index fingertip is landmark 8. Its normalized coordinates are converted into canvas coordinates, with the camera view mirrored so movement feels natural.

Tips for better air drawing
Use a well-lit room and keep your hand inside the camera frame. A simple, uncluttered background can make hand tracking more reliable. Smooth, deliberate finger movements usually produce cleaner lines than very fast movements.
Privacy and limitations
Camera access is requested only after you press Start Camera. Hand tracking runs in the browser using MediaPipe. The page does not need to upload your webcam video to a Slopbin server. Performance depends on your browser, device, lighting, and camera quality.
