Simple definition of Local
"On-device" or "local" means that an AI model or software runs directly on your device, like a phone, tablet, or computer, instead of needing to connect to big servers on the internet (called "the cloud").
This makes things faster, can work even without an internet connection, and helps protect your privacy because your data stays on your device and doesn’t get sent to other places. However, on-device AI is less powerful than cloud-based AI because devices have limited storage and processing power.
How to explain Local to kids
Tell your child that "on-device" means the smart part of a phone or tablet does all the thinking right there, without needing to send your information away. It’s like solving a puzzle using what you already have with you, and it helps keep your stuff safe and private.
Here’s how to think about it
Imagine doing your homework using only the tools in your backpack instead of going to the school library. You don’t need to leave the classroom, and no one else sees what you’re working on. The downside is your backpack can't hold everything the library can.
That’s what on-device means, it all happens right there, and it keeps your stuff more private, but it can't provide as much help as the much bigger cloud AI tools.
