Talk to your assistant

It learns you, like a real personal assistant.

Just tell your AI Assistant what matters. Share instructions and context once, and it adapts how it answers, who it puts through and what it notes for you.

I'm in meetings till 4 today. Only put Amma and the school through.
Got it. I'll take messages from everyone else and send you a summary at 4.
If the courier calls, ask them to leave it with security.
Noted. I'll remember that for future deliveries too.
