Point a webcam at yourself, record a few seconds for each category you want to teach, press train, and the model starts classifying live. No code is involved at any stage. The finished model exports and drops into a website or a small hardware project.
Watching a classifier learn to tell your left hand from your right inside a minute makes machine learning feel like a mechanism rather than magic.
