Skip the always-on mic: build a one-action Shortcut that starts a Grok Bot voice chat, then just say "Hey Siri, Grok Bot" to open it, even from the lock screen.
You want hands-free Grok Bot voice chat on iPhone without an always-listening mic.
"Hey Siri, Grok Bot" opens a Grok Bot voice chat, with nothing new listening in the background.
Open Shortcuts, tap +, Add Action, search "Grok Bot" and pick "Start a Voice Chat with Bot".
Rename the shortcut "Grok Bot" (or any name Siri hears easily).
In the shortcut's details, turn on "Allow Running When Locked".
Say "Hey Siri, Grok Bot" to open the voice chat.
What's good: it rides on Siri's existing wake word, so no orange mic dot, no extra battery drain and no false triggers from the TV. The catch: you still go through Siri, and a locked phone needs Face ID first.
