One tap is all it takes to teach it your preferences, making it smarter and more accurate over time.

Poly - Your Built-In AI Life Assistant

Poly isn't a bolted-on chatbot; it's your integrated executive assistant that knows everything about your inbox, schedule, and priorities.

It pulls information from across your connected accounts to give you instant, comprehensive answers, helping you get things done instead of just managing messages. It's like having a personal EA for all your life admin.
