How is the "Nano" version of Google Gemini AI useful for everyday users?

Gemini Nano useful because it is small and fast. It can check your grammar when typing message. It can help you reply fast in WhatsApp. It can give short summary of long text. All these small help save time everyday.

I think the best use of Nano is for privacy. When AI runs inside phone, your chat or notes not go to internet. That is safer. Many people worry about privacy today, so Nano is good.
