Test six AI homework tutors on one maths problem with a 14-year-old and pick ChatGPT Study Mode

During back-to-school prep, Laura Cioffi and their 14-year-old daughter gave the same cone surface-area problem to ChatGPT Study Mode, Photomath, Socratic by Google, Claude, Brainly AI and Duolingo Math. Photomath got it wrong; Claude and Socratic were right but too academic; Brainly gave clear steps; Duolingo felt like a game. ChatGPT Study Mode asked the 14-year-old for the values, walked them through the formula and checked their understanding; the teen said it didn't make them feel 'thick'.

Plan a dog-friendly 7-day RV trip with short drives using ChatGPT

Planning an RV trip from Tampa with their partner and their dog, a poster asked ChatGPT for a 7-day route with no drive over 4 hours, waterfalls and short hikes, and dog-friendly stops. They also used it to check which state parks allow dogs on trails, how to connect a 30-amp RV to a 50-amp site, campfire cooking steps and campgrounds with cell service. They say it gave a day-by-day route with mileage and drive times, and dinner was saved.

Moving house, starting a new job and turning 40 within two weeks, a poster asked ChatGPT to act as their moving assistant and create a day-by-day plan up to the move. They shared their prompt, which asks for 3 to 5 priority tasks a day, a packing focus, admin tasks, 15-minute meals using what's left in the kitchen, a moving-day food plan and a first-day survival box checklist. They say the clear to-do list made everything feel more manageable.

Turn a week of school emails, PDFs and WhatsApp messages into a one-page parent action plan with a ChatGPT prompt

Claire Calvert shares a setup for parents buried in school communications: either a custom GPT called 'School PA' or a regular chat where you upload emails saved as PDFs, screenshots and forwarded WhatsApp messages each week. The prompt asks ChatGPT to extract every event, highlight parent decisions, tag deadlines by urgency with days remaining, and produce a conflict-free one-page weekly plan, without assuming information that isn't there.

Get a full refund for event tickets the seller didn't have, by finding a gap in their terms with ChatGPT

After buying event tickets from a resale site and finding the seller didn't have them in hand, a buyer was refused a refund. They gave ChatGPT the site's terms of service, and it found they required buyers to expressly accept a delayed-fulfilment model, which they were never asked to do at checkout. With ChatGPT they drafted messages citing this and filed complaints with the BBB, FTC and California Attorney General, and say they had a full refund within days.

Keep two sick cats' vet updates, records and decisions straight in a ChatGPT project while away

On holiday when both cats fell seriously ill, with their partner handling vet visits at home, Harriet Meyer set up a 'cat project' in ChatGPT. They uploaded the cats' medical histories, transcripts from vet calls and notes on temperament, and used it to make sense of updates, work out what to ask the vets, and think through difficult decisions. Meyer says it didn't replace the vets but helped them think clearly; one cat recovered, while the other was still in hospital when they posted.

Return a faulty used car for a full refund under UK consumer law with ChatGPT's help

Four weeks after buying a used car that kept developing problems, even after a warranty repair, a UK buyer thought they were stuck: the dealer's 30-day return only covered up to 250 miles and they'd done about 500. ChatGPT told them about their rights under the Consumer Rights Act 2015, and they say one email later the dealer agreed to take the car back with a full refund.

Handle parking, road tolls and EV charging questions on a European road trip with ChatGPT and Grok

On a family road trip through Germany, Austria, Italy, Croatia and Slovenia, a poster used ChatGPT and Grok as an on-the-go assistant: planning village visits, walks and beaches, finding fairly-priced safe parking, choosing local beers and wines, and answering first-time EV road-trip questions such as where to buy national vignettes online, road taxes and trip-time estimates.

Stop overdrafting by staggering bills across paychecks with a ChatGPT budget plan

A freelance writer who kept overdrafting despite a steady job listed their fixed expenses and due dates and asked ChatGPT for a monthly budget. It suggested splitting each paycheck, paying current bills with one part and saving the rest for bills due later, then broke down their remaining money into savings, debt repayment and personal spending. They say the first month was tough, but since then they haven't overdrafted at all; they found they had to be very specific with their prompts.

Fix a tankless water heater a company called 'shot' with Grok and ChatGPT

After a repair company said their tankless water heater was shot and quoted $6,900 to install a new one, a homeowner watched YouTube videos and chatted with Grok 4 and OpenAI's o3 model. The homeowner says they fixed it themselves the next morning in less than 30 minutes and then called the company to get their $100 back.

A journalist's write-up describes a bride planning a DIY, 120-person outdoor wedding in Las Vegas who says about 85 percent of the wedding to-dos were created, organised or completed with AI. Their request to ChatGPT for common and uncommon tasks produced a spreadsheet of 200 suggestions; it also helped with the day-of schedule, seating chart, menu, website text, vendor query letters and budget, and found the officiant and cake maker. They say it sometimes suggested vendors no longer in town, which a phone call cleared up.

Plan a 20th anniversary party, from crowd-size recipes to a helper playbook, with ChatGPT

Hosting a big 20th wedding anniversary party, a poster used ChatGPT to build the event plan, name signature cocktails and mocktails, convert a pan-fried crab cake recipe into mini air-fried versions for a crowd, create a gluten-free dessert a guest couldn't tell was gluten-free, write a playbook for the teenagers hired to help, write signage and checklists, plan the evening timeline with a vow renewal, and even fix a printer jam.

Win a $2,100 settlement from a tow driver who dented a car, with guidance from ChatGPT and Gemini

With no pre-tow photo and a dent left by a tow truck driver hired by their apartment, a poster asked ChatGPT o3 and Gemini 2.5 Flash whether to claim on insurance or leave it. Both suggested settling directly with the driver, who also lacked a pre-tow photo. Over five weeks, with o3's guidance, they built an email trail, set deadlines and asked for evidence, and say they won a $2100 settlement in 35 days.

Make a personalized vacation packing checklist with a shared ChatGPT prompt

TechRadar's John-Anthony Disotto shares a long 'travel assistant' prompt (originally posted on Reddit) that asks for your age, destination and trip details, then builds a categorized packing checklist with clothing, tech, toiletries, luggage type and one commonly forgotten item. Trying it for their own trip, they say ChatGPT broke down their wardrobe into specific business-casual outfits, and that results are only as good as the details you give it.

Plan an urgent passport agency visit before a vacation with ChatGPT

With a passport expired just before a vacation, Dan Sanchez asked ChatGPT's o3 model to search for options. Together they worked out that Sanchez would need to drive to Atlanta for an expedited passport; when the government sites weren't clear about the process, ChatGPT filled gaps from Reddit and travel forums and helped with the appointment, hotels, where to be, what to bring, what to expect and backup plans. Sanchez says they got through the passport agency smoothly; the post doesn't say whether the passport was issued that day.

Pick a holiday destination for three friends from their questionnaires with ChatGPT and Gemini Deep Research

For an AI-planned trip with two colleagues, TechRadar's Josephine Watson sent the same Deep Research prompt and three completed preference questionnaires to ChatGPT and Gemini: four days, one base, about $2,000 each, scenic and filming-friendly. Gemini returned five well-known picks such as Lagos and Mallorca in under five minutes. ChatGPT asked follow-up questions first, then ran 110 searches across 34 sources in 16 minutes and suggested Santorini, Madeira, the Bay of Kotor, Cappadocia and Essaouira. ChatGPT came out on top in their head-to-head.

Pick a new country to move to from a list of must-haves with ChatGPT

Needing to leave Canada, a poster and their partner gave ChatGPT a list of requirements: what they loved about Vancouver, economic viability, quality of life and more.

Get out of a $75 parking ticket with a polite ChatGPT-written appeal

Compare ChatGPT and Gemini for healthy meal ideas and a week of cheap lunches

Tom's Guide's Josh Render photographed chicken thighs, salad and avocados and asked ChatGPT and Gemini for a healthy meal with those ingredients, then asked each for a week of varied, healthy, low-cost lunches for losing weight. They preferred Gemini for both: it explained how to prepare the chicken beforehand and was more comprehensive, though wordier; ChatGPT's terser plan was easier to print and hang on the fridge.

Plan a month-long family road trip with kosher meals using ChatGPT and Grok

Planning a month-long road trip for a family of seven, a poster used ChatGPT and Grok to map routes between national parks without backtracking, break long drives into kid-friendly segments, find lodging that fits, research kosher food and the kitchen kit needed for Shabbos, and create packing lists. They note it didn't understand kosher certification symbols and that it's not perfect.

Set up tap-to-see box inventories with NFC tags for a move with ChatGPT

Moving out with belongings stored at a friend's house while staying with family before three weeks in Europe, Nicole Leffer asked ChatGPT for a way to know what was in each box without opening it. It suggested NFC sticker tags (100 for about $26) and walked through setting up iPhone Shortcuts so each tag opens a numbered note. As boxes were packed, including by movers, each note got the box's destination, photos and a list of contents. Tapping a box now shows what's inside, and searching notes found an external monitor without opening boxes.

Organise symptoms, past tests and questions before a specialist appointment with ChatGPT

Before a gastroenterologist appointment, a patient used ChatGPT to map out their symptoms, track the tests they'd already had and write the specific questions they wanted to ask, so they wouldn't forget anything in a short visit.
