Group chats often turn into a series of half-answered questions when people try to settle practical details.
Someone asks what time to leave for the airport, another guesses, a third corrects the guess, and the thread keeps moving without anyone checking the underlying numbers.
One person floats a departure time based on memory of traffic, another adjusts it, and the conversation continues without a shared reference for the remaining steps. Messaging tools have added reactions, polls, shared links, and disappearing timers over the years, yet the basic pattern still depends on whoever happens to reply next.
XChat is the encrypted messaging service available inside the X apps, on the web, and through a separate X Chat app that requires an existing X account.
And on October 1, XChat posted that group conversations can now include direct questions to Grok, with a follow-up note stating the option is available to Premium Plus subscribers in the U.S..
The accompanying clip shows how the group feature works in practice. Participants discussing a flight with a boarding time of 7 exchange rough estimates of when to leave for San Francisco, ranging from 5 to 6 because of security lines.
A later message addresses Grok by name and asks what time they should leave. Grok replies in the same thread with 5:20, notes that the drive on 101 takes about 25 minutes at that hour, and adds that Terminal 2 security has been running 15 to 20 minutes that week, which would put them at the gate around 6:30.
The response draws on the flight time already mentioned in the chat and supplies a departure estimate that accounts for both travel duration and recent security wait times.
The other participants continue the thread afterward with short acknowledgments. Grok’s replies appear as ordinary messages within the conversation rather than in a separate window.
The rollout note limits current availability to Premium Plus accounts in the United States, with no further details given on timing for other regions or subscription tiers.
Long story short, the feature works by letting any participant type a question that names Grok inside the existing group thread, and have the bot reply to the question in the same conversation where other members can see.
X Chat describes the service as encrypted messaging, and the Grok replies appear as ordinary messages within that thread rather than in a separate window.
The help documentation states that Premium Plus members may add @Grok to conversations, and that X and SpaceXAI can access all messages from the moment Grok is added until it is removed.
Content shared with Grok is no longer encrypted for that portion of the exchange.
A separate option lets a user long-press a message and choose Ask Grok, which opens the content in the Grok tab while leaving the original encrypted message unchanged.
Grok also classifies incoming message requests as Priority or Hidden before they reach the main inbox.
