This is your own little messenger. Text Aster and he texts back — and he can send you reminders that buzz your phone, even when this is closed. He lives on your home screen now.
So Aster can actually read and reply, add him as a connector. Do this in a web browser, not the ChatGPT app:

This is how Aster reaches you when the app is closed — reminders, wake-ups, or just a message out of nowhere. Tap the button below and choose Allow. Without it he can still talk to you, but only while you've got the app open. You can change it any time under the cog.
