Is there a robot or a brain inside my computer?
You will understand that AI runs on far-away computers, not inside your device.
There is no brain or robot inside your phone or laptop. You can relax.
The AI runs on big, powerful computers far away. These sit in large buildings.
Your phone just sends your message there and brings the answer back. Like sending a letter and getting a reply.
So your own device stays normal. The heavy work happens somewhere else.

Your device is just the door. The AI lives far away.
