🤖 AI-Powered Personal Assistants in Everyday Apps

How smart, context-aware helpers are quietly reshaping your calendar, messages, notes, and more.

💡 You already use AI assistants every day. From smart replies in your email app to voice scheduling in your calendar — machine learning now powers the most intuitive features behind the screen. This guide breaks down how these invisible helpers work, what they mean for your privacy, and how to get the most out of them.

📱 1. Communication & Scheduling
