Constraints

Update the Grok Bot app on your iPhone, create a Shortcut with the action "Start Voice Chat with Bot," then bind it in Settings → Accessibility → Vocal Shortcuts and record your wake phrase (e.g., "Hi Grok"). On the lock screen, wake the display and complete Face ID unlock first; after that, interaction can be fully hands-free.

What they did

Author Liu_zhongxisn used iOS system features (Shortcuts and Accessibility → Vocal Shortcuts) to bind Grok Bot's real-time voice chat to a custom spoken wake phrase on an iPhone.

How it went

The author reported that, after setup, speaking the wake phrase launches a real-time voice session with Grok Bot, allowing voice commands to control the phone—such as adding calendar events or checking messages. On the lock screen, the display must be woken and Face ID must unlock the device before fully hands-free operation is possible. (Author's claim; not verified by this site.)

Worth knowing

The wake phrase is customizable and not limited to "Hi Grok." The source does not state the minimum iOS version, minimum Grok Bot version, or whether a paid Grok subscription is required. The attached demo video was not transcribed, so its contents could not be independently verified. No additional technical implementation beyond these three system-configuration steps appears in the source.

Steps

  1. Update Grok Bot App

    Go to the App Store and update Grok Bot to the latest version.

  2. Create a Shortcut

    Open the Shortcuts app, create a new shortcut, and add the action "Start Voice Chat with Bot."

  3. Bind a Vocal Shortcut

    Go to Settings → Accessibility → Vocal Shortcuts, bind the shortcut you just created, and record your chosen wake phrase three times (for example, "Hi Grok").
