prnvbaraiya/Air-Writing-and-Character-Recognition ? reverse-engineered prompt

Build me a simple web app where I can use my webcam to write letters or numbers in the air with my index finger, and then the app tells me what I drew.

I want it to open in the browser on localhost, show the live camera feed, track my hand, let me “draw” on the screen with my finger, and recognize the character after I finish. It should work for both alphabets and digits, and feel easy to use like a small demo project. If you need to check current docs for OpenCV, Flask, or hand tracking, go ahead and do that.

Please keep it clean and lightweight, with a basic page for the camera view and result display, plus simple controls like clear or reset if that makes sense. Make sure it runs locally with a straightforward setup and includes everything needed so I can start it quickly and test it right away.
