A user set up a Grok Bot food prep team under his chief-of-staff bot: a Meal Organiser that knows the lunches and dinners he likes, a Shopper that fills his grocery cart, and a Cooking Bot that walks him through each meal. He says the shopping takes under 3 minutes versus about an hour at the shops or 30 minutes online, and meals take under 20 minutes. He checks out himself.

A user who tried Meta's Muse for insurance quotes and online shopping says it kept missing the lowest price.

It also missed the cheapest home insurance quote, though it suggested ways to lower the premium.

A journalist had Grok Bot order him Chicken McNuggets. It worked, but the McDonald's receipt made it look like the bot had ordered 110 nuggets for $13. It was really one 10-piece, the way the receipt displays the item.
A SiriusXM subscriber asked Grok Bot to find the best deal it could. It found a $2.99/month offer, logged into the account (the owner typed the 2FA code into a secure pop-up), opened a chat with a SiriusXM rep to get the deal, checked the card on file, asked for a final OK, then finished the enrollment.
Can a bot handle the grunt work of reselling clothes? She had listed clothing on eBay in big lots because there was too much to list one by one, even though buyers kept asking for single items. Her Grok Bot broke the lots into individual listings, then cross-listed all 150 pieces on Poshmark and Depop in a few hours. It also walked her through email forwarding and filters so sale notifications go to the bot's own inbox, and it takes a sold item down from the other sites on its own. One gap: it can't reach app-only settings like Depop's offer floors.
Can a bot find the right repair part from a text message? His dad texted him about their broken washing machine. He screenshotted the text, told Grok Bot which washer it was, and in under 30 seconds it found 4 options for genuine and aftermarket replacement parts.
Hate calling around for quotes? He needed a seasonal tire swap (winter tires already on rims) and connected Muse to a voice-calling service with a script: price with tax, the right lifting pucks for his car, torque to spec (175 Nm), and availability after mid-November. The first call failed because it couldn't say where he was. With his area added, quotes came back at $120 plus tax, $50 tax-in (mobile, but he supplies the pucks) and $168 plus tax. One went to voicemail. He then scheduled 18 more calls and updated them all at once when he remembered 4 missing details. Every call produced a transcript.
Is that '20% off' real? Before buying anything this week, she had Grok Bot check price history. The Echo Show 11 was $199.99 against a $249.99 'list price', but it sat around $220 most of the year and was $149.99 on Oct 2. AirPods Pro 3 were $199 against a $249 'list price' that's just the launch price; $199 is what they cost now. One meh deal, one fake discount.
They returned a car seat. A few days later Meta Muse told him, without being asked, that the refund came back $70 short because of a restocking fee they never knew about. It gave him Amazon's phone number and a script with the order number. One call later, Amazon credited the $70.
He uses Grok Bot to sell on Facebook Marketplace with strict rules. Titles follow one fixed template. It researches a price and explains why. It never publishes without a separate yes from him. The price goes only in the price field, it never shares his home address (it suggests a public meetup spot), it answers only routine questions about the item, and it never negotiates or agrees to pickup times.
Restaurant Business reporter Joe Guszkowski had Meta Muse order a pepperoni pizza from Pizza Hut. It worked through its own browser and paid with Stripe's Link, but it took about 4.5 minutes, compared with about 40 seconds doing it himself. It also told him, from his email, when an Amazon package arrived.
PYMNTS tested Meta Muse on three everyday jobs: reordering 6 rolls of toilet paper on Amazon, ordering Domino's and booking on Resy. None went through. Most of the trouble was setup: sharing Amazon logins through a secure link, connecting Gmail and Calendar one at a time, and a Stripe Link checkout that didn't complete. The same reorder took them under 30 seconds on Amazon directly.
YouTuber Rostyslav Dzhohola gave his ChatGPT Dots assistant, Skippy, real errands live on one voice call. It booked and then cancelled an OpenTable reservation, ordered Popeyes on DoorDash (with a wrong-address moment along the way), ordered H-E-B groceries, sent an email invite and added the dinner to Google Calendar. Some steps were slow, and it refused to buy beer.
His local pizza shop had moved. Grok Bot found the new location and an $8.99 coupon, then placed the order by phone. He called the shop afterward to check, and the order was real.

He had filled an Instacart cart for a same-day Costco order, then got an Uber Eats email with a discount. He told a new Grok Bot to place the same order through Uber Eats.

Can a bot shop for you at Walmart without trouble? An AuADHD user says Meta Muse cancelled her Mint Mobile account by starting its own support chat, even though a rep had told her she'd need to call. Then, overwhelmed planning her daughter's birthday party, she had Muse find the best prices and put together a Walmart cart for her to approve.

It reminds them to photo the receipt, logs prices and quantities, warns when they're running low and sends the receipts to an expense bot.
Tired of 20 open tabs while car shopping? This user had their Grok Bot search for vehicles that match their criteria and keep a spreadsheet of what it found, with details and clickable links.

The call took 2 minutes 6 seconds, and the bot sent him a recap and the recording.
He saved all 5 of his credit cards in Grok Bot's vault and now buys by text. He got his kids 2 Garmin watches, a DribbleUp smart ball and an Ollyball without opening a website.
