Would you send an AI a photo of your credit card and tell it to go shopping?
Elon Musk says you can.
On Saturday, October 10, he posted that people could buy things by sending Grok Bot a picture of their card.
On Sunday, it ordered Lego sets for him. By Tuesday, October 13, five sets had arrived. (Mashable put them at $241.34 on Lego's site.)
Then on Thursday, October 15, a user said Grok Bot had booked them a flight from a card photo. Musk replied:
"This works well. If Grok Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole."
That's a big promise.
Right after this: what the fine print actually says, and five rules before you let any AI buy for you.
Now a quick word from today's sponsor.
Stop typing AI prompts. Start talking.
You think 4x faster than you type. So why are you typing prompts? Wispr Flow turns your voice into ready-to-paste text inside any AI tool. Speak naturally, tangents and all, and Flow cleans it up. Available on Mac, Windows, iPhone, and Android.
Right. Back to it.
What the fine print says
The terms of service for Grok's company were updated on October 12. They say Grok can take "Agentic Actions," including with "financial institutions."
They also say: "We are not responsible for User Content or Agentic Actions."
According to Teslarati, xAI's consumer terms also make you responsible for what its agents do, and generally cap liability at the fees you paid or $100, whichever is greater.
The terms don't mention Musk's promise. So for now, the promise is a post on X, and the terms are what you agreed to.
Amazon said no
One user's Grok Bot got locked out of Amazon. The message: "Continued access by an unauthorized AI agent violates Amazon's Conditions of Use, to which our customers have agreed."
Musk's answer: ask Grok to "buy what you want someplace else." He also floated starting "a competitor to Amazon."
Who can use it
Grok Bot isn't free. It needs The X Subscription, which starts at $30 a month. Musk's words: "there is no free tier."
This isn't just a Grok thing
ChatGPT's Chrome extension can fill in forms for you. Gemini now connects to apps like Instacart and OpenTable.
Shopping agents are coming to the assistants you already use. So the rules below apply to all of them.
Five rules before you let any AI buy for you
Never send a photo of your card. xAI itself tells users to keep personal information out of prompts.
Use a separate card with a low limit. If your bank offers virtual cards, this is what they're for.
Start with something cheap and returnable. A $15 order teaches you as much as a $1,500 one.
Make it stop before it pays. You approve the total, every time.
Trust the terms, not the post. A promise on social media isn't a refund policy.
The prompt
Copy this for your first AI shopping job, with any assistant:
Find me [item] for under $[budget].
Show me the total with shipping and tax, the seller, the delivery date and the return policy.
Don't buy anything. Wait until I reply "buy."The last line is your brake. Keep it in every shopping prompt.
Make it stick
Set up that low-limit card this week, before you need it.
Then every AI shopping test runs on money you've already decided you can lose.
Handing work to AI goes best when it knows exactly what it can and can't do without you. That's the whole idea behind The One-Person Company Playbook.
It's the complete setup for running a business where AI does the work of a full team. Inside:
A company folder with your brief, pipeline tracker and invoice log already laid out, so any AI picks up where you left off
Thirty AI roles across six departments, from sales to finance, ready to use
Six jobs that run on a clock: the morning briefing, follow-ups, invoice checks and more
The step-by-step path from picking a business model to your first paying customer
Works on Claude, ChatGPT, Gemini or Grok, whichever you already pay for.
The catch: it takes about eight hours over a weekend to set up. After that, it's yours. $97, one-time (down from $297).
Talk tomorrow,
