Official account announces availability
@bot, the official account of "Grok Bot," the AI agent of SpaceX subsidiary SpaceXAI (formerly xAI), posted on X on Nov. 4 (Nov. 5 Japan time) that the bot can now make phone calls on users' behalf. It attached a 42-second promotional video.
Grok Bot can now make phone calls.
The announcement came 10 days after Elon Musk introduced it on Oct. 25 (the evening of the same day Japan time) as a feature that calls people and businesses on users' behalf. At the time, it was reported to be available only in the beta version, and the official account had not posted details on availability.
Asks for approval before dialing, users can take over mid-call
In the promotional video, the bot notices that an internet service contract will renew in three days and asks the user whether to call to cancel it. Before dialing, it shows a "Phone call" card with the party to be called and "Cancel" and "Call" buttons, and dials when the user presses one.
During the call, what both sides say is displayed as text, along with a "Take over" button for the user to take over the call and an "End call" button to hang up. In the video, the bot turns down the representative's retention offer of a 10% discount for a year, confirms the cancellation and ends the call. It reported the result to the user in the chat.
The day before, on Nov. 3 (Nov. 4 Japan time), Musk posted "Try asking Grok @Bot to make calls!" quoting a demo in which user Sawyer Merritt posted audio of an actual call.
Try asking Grok @Bot to make calls!
Merritt reported that when the other party asks something the bot does not know, an answer field appears in the chat, and the bot relays the answer the user types to the other party. SpaceXAI has not officially explained this mechanism.
Post does not state plans or countries covered
The post by @bot did not state which plans can use the feature, whether there is an extra charge or which countries it is available in. It also did not say whether the bot identifies itself as AI to the person it calls. Grok Bot's official documentation also had no mention of the calling feature as of Nov. 5.
According to Teslarati, Grok Bot's terms require it to identify itself on every call as a "virtual assistant" acting on the user's behalf and to say that the call may be recorded. Sales calls, mass dialing and impersonation are prohibited. For now, it can call only U.S. numbers.
Grok Bot itself is available on SpaceXAI's "The X Subscription" plans "Premium" at $30 a month and the higher "Super" ($100) and "Ultra" ($200). Peter Yang, whom Teslarati describes as having worked on the feature, posted that all users can now call U.S. businesses.
Users report negotiating price cuts and more
Teslarati reported examples of calls described by users. Yang reported that the bot called Comcast for about 25 minutes and, using a cheaper competing fiber service as leverage, negotiated the monthly bill down from $84 to $45. Before accepting the final terms, the bot asked for his approval, he said.
Other reported examples included a 51-minute call that recovered a $100 gift card for Verizon's "Fios" fiber service and booking a same-day pediatrician appointment. On the other hand, there was also a report that a representative would not accept a cancellation once they realized it was AI.
How long calls count against usage limits undisclosed
SpaceXAI has not disclosed how calls count toward weekly usage. Grok Bot usage is set weekly and resets every week.
On Nov. 1 (Nov. 2 Japan time), Musk posted on X that the cost of serving Grok Bot had been unsustainably high relative to revenue, replying to a user who said they had run out of their usage allowance midweek. At its July-September earnings call on Oct. 20, SpaceX said paid weekly users of Grok Bot reached 800,000 in early October.
Available less than 2 weeks after leak
The feature first became known through posts by users who examined the beta version. On Oct. 24 (Oct. 25 Japan time), @blankspeaker posted that beta version 0.77 had a calling screen, and @alexmichaelio described features for dialing, holding, keypad input, transferring to departments and transcription. Musk's introduction came the next day, and the official account's announcement came 11 days after the leak post.

Google and Meta also make calls on users' behalf
Other companies also offer features in which AI calls businesses on users' behalf. Google announced "Duplex," which completes reservations and other tasks over the phone, in 2018, and in July 2025 launched a feature in the U.S. that calls local businesses from Search to ask about prices and availability. Meta's agent "Muse" can also make calls on users' behalf.
