Grok Bot can now use Calendar, Reminders, Contacts and other apps on your phone

xAI’s Grok Bot account posted late on 22 October that Grok Bot “can now use Calendar, Reminders, Contacts, and more apps on your phone,” rolling out on iOS and Android. Earlier that day the same account announced 1Password sign-ins, covered in our 1Password for Agents piece.

The six permissions

The screen attached to the post lists six permissions, each with its own Allow button:

1. Messages: read and send messages.
2. Location: find places near you.
3. Calendar: see your day and add events.
4. Home: control lights, locks and more.
5. Reminders: set and check reminders.
6. Contacts: find and add contacts.

Each is granted on its own, so you can turn on Calendar without Messages.

What is not documented

The Grok Bot mobile page still covers only the basics, iOS 18 or later and Android 9 or later on eligible plans, and says nothing about these integrations. There is no written account yet of what data leaves the phone, how long it is kept, or which actions ask for approval first.

Early reports

Grok’s own replies on X say the feature needs the latest Grok Bot phone app; the Grok chat app alone does not provide it. One iPhone user reports that home controls, reminders, calendar edits, contact lookups, alarms and location worked, but the Grok Bot app had to be open, and sending iMessages, music and TV control did not work yet. That sits oddly with the “send messages” line on the permission screen and may differ between iOS and Android.

Why it matters

Calendar and reminders are where a personal assistant earns its keep, and the phone is where they live. The permission most worth a second look is Messages, because it lets an agent speak for you.
