What is Gemini Nano?

Gemini Nano is Google's smallest AI model, built directly into Chrome (v127+). Unlike cloud AI, it runs entirely on your device — no internet connection needed, nothing sent to Google or anyone else. It's the same technology that powers on-device features in Pixel phones. CommentIQ uses it to analyse comments without ever touching a server.
