$20 back when an order came without its case

The poster had his Grok Bot order an electric toothbrush from Walgreens. The listing said it came with a travel case, but the case wasn't in the box. The bot suggested asking for a partial refund instead of sending the whole thing back. It then opened the online chat on the Walgreens website, explained the problem and handled the whole conversation by itself. Walgreens gave him a $20 refund and he kept the toothbrush. It's a small win, but it's the kind of thing most people let slide because a support chat feels like more trouble than the money is worth. Asking for a partial refund on a missing part is often easier than a full return, and the store keeps the sale.

A duplicate pest control plan found and cancelled

The poster had been paying Terminix twice for the same house for two years and never noticed. His Grok Bot spotted the double charge, called Terminix, went through the phone menus, and then kept texting the company's support line until it was sorted out. He kept the plan he wanted, the duplicate was cancelled, and he says $834.34 is on its way back to him. He never had to pick up the phone himself. Note that the refund was still "headed back" when he posted, so it wasn't in his account yet. Duplicate service plans are easy to miss when a home service bills on autopay, especially after a move, a change of card or a sales call that opens a second account.

He says the duplicate was cancelled and $834.34 is headed back to him. The refund hadn't arrived yet when he posted.

Internet bill cut $30 a month, plus a free recall fix

A few weeks into using Grok Bot, the poster listed what it had done so far. It got his internet bill lowered by $30 a month, which he says covers the cost of the subscription. It also found that a $2 hoverboard he bought at Goodwill was under a recall, so instead of paying over $100 for a new battery he got a replacement for free. He says the battery arrived and works. The bot also listed a Magic card on eBay for him after local shops offered too little. Next, he's having it go through his old tax returns. The recall find is the one most people would miss: secondhand items can still be covered by a recall even if you didn't buy them new, and the U.S. Consumer Product Safety Commission keeps a searchable list at cpsc.gov.

He says his internet bill went down $30 a month and the recall replacement battery came free.

Doctor visit booked from just an insurance card

The poster had just moved to Texas and needed a first visit with a primary care doctor, but didn't know where the office was or how his insurance worked. He gave his Grok Bot one thing: his insurance card. The bot searched his 4 email accounts, found the card as a PDF and read the plan for him: copay, deductible, out-of-pocket max and the named primary care doctor. The card only had the doctor's name, so the bot worked out which clinic that doctor practices at, found the earliest open time and went through a 9-step online booking. Right before the last step it stopped and asked him to confirm. After his yes it booked a visit for the next morning, handled the confirmation email and set a reminder. It then turned the clinic's health questions into one card he could tap through and filled in the intake forms from his answers. He says the whole thing took about 15 minutes. He also shares the bot as a template he made, so keep in mind he is promoting it.

A viral video checked frame by frame

A viral post claimed an AI tool had found thousands of hidden photos on someone's Android phone, with a screen recording as proof. The poster asked Gemini to look into it using a Task in the Gemini app. It pulled out all 423 frames of the clip and read what was on screen. The last few frames showed a lock screen with the date "Thu, 19 October" and "No SIM", and October 19 was a Thursday in 2023, not 2026. The scrolling text turned out to be phone startup logs, and the clip matched a YouTube Short posted on October 19, 2023. A handy way to check a dramatic video before you share it.

Let the agent draft emails, and you send them

The poster says Claude Cowork badly mishandled some important emails for her. Her fix is to use the agent only to write drafts and decide herself what actually goes out. It's a simple rule that keeps most email mistakes from reaching anyone.
