Musk promotes assigning Grok to the iPhone Action Button for instant access

Elon Musk says on X that Grok can be assigned to a phone button for instant access.

In a post dated October 13, 2026, he tells users to assign the Grok bot to the phone's button. A user shares a workflow in which pressing the iPhone Action Button opens Grok in voice mode, where it can take tasks and deadlines and delegate them to bots. The report is Musk's promotion of the feature; it does not include independent testing of how the setup performs.
