ChatGPT examples: 282 real use cases with prompts

Visualize a furniture layout for an empty corner from a photo with ChatGPT

After three days lost in Pinterest boards, Tom's Guide's Kaycee Hill uploaded an unedited photo of an empty living-room corner to ChatGPT and described the chair, side table, bookcase and lamp they wanted. They then resized, removed and recoloured pieces in the generated images to test risky choices, and say they finished with a visual blueprint of what sizes to measure for and colours to buy, saving hundreds in potential returns.

Understand a formal Japanese notice from a new landlord and reply properly with ChatGPT

A foreign resident in Osaka found a formal, indirect notice from their building's new owners. They photographed it and ChatGPT translated it, explained the implied meaning and flagged what to ask next; they checked the points with a real estate friend and emailed a formal Japanese reply. At the meeting, the owners asked tenants to leave and offered to cover moving costs and new-apartment fees, and they recorded and translated the meeting with Gemini and ChatGPT.

File an Indian income tax return with ChatGPT as a cross-checker (it got some capital gains wrong)

A filer in India used ChatGPT, with documents in a Project, as their main assistant for their income tax return. They say it was good at flagging common pitfalls and asking for supporting documents, and most valuable for checking calculations across documents. But it gave confident wrong guidance on REIT dividends and sales, misclassified some short- and long-term capital gains even with broker reports, and sometimes got totals wrong; they had to verify every important number. They'd still use it next year.

Make a wedding seating chart from a guest spreadsheet with ChatGPT

Android Police's Olivia Locksley uploaded their guest spreadsheet (names, partners, relation to the couple) to ChatGPT with the number of tables and seats, general groupings and couples who must sit together. They then added nuance: spacing talkative and shy guests, seating a younger relative with their college friends and keeping feuding relatives apart. They say it handled the hard part, but the final draft still had to be checked and tweaked by hand.

A tax deduction strategy from ChatGPT that would have cost a business owner: an accountant's story

An accountant says a client came in convinced ChatGPT had found a deduction strategy saving them $40,000 in taxes. The accountant says the deduction category was misapplied for the client's business entity and the strategy relied on a rule changed by recent guidance; they caught it and filed correctly.

Ask ChatGPT, Gemini and Claude for Prime Day tech picks, and check the discounts they claim

A TechRadar editor asked ChatGPT, Gemini and Claude what discounted tech to buy on Prime Day. Gemini focused on deals but overstated one: it said Sony WH-1000XM5 headphones were 50% off when they were actually 20% off at $198 (was $248). ChatGPT tailored picks to their interests from past chats but was less tuned in to actual discounts, and Claude, which knew least about them, gave fairly generic deals.

Keep a shared puppy feeding, potty and nap log in a ChatGPT group chat

A couple with an 8-week-old puppy use one shared ChatGPT group chat to log when the puppy eats, goes potty and naps, plus crate notes and 'is this normal?' questions, then ask ChatGPT to organise the pattern. The poster says it acts as shared memory, not a replacement for a vet or trainer.

Catalogue a DVD collection for resale from shelf photos with ChatGPT

A How-To Geek writer photographed the spines of hundreds of DVDs and Blu-rays and asked ChatGPT to list them in a spreadsheet with columns useful for resale listings. It built the spreadsheet, correctly classified some PSP discs on the same shelf, and filled in more details on a second pass. They still had to review it by hand: some titles weren't legible, and they warn the AI can hallucinate titles not in the photos.

Send an email straight from ChatGPT through a connected Gmail account (attachments didn't work)

A TechRadar editor connected Gmail to ChatGPT and asked it to write and send an email with a story idea, background and a source link. ChatGPT showed the exact email and asked them to Allow or Deny; after they approved, it arrived seconds later. But it failed when they tried to add an attachment, and the feature only works on the web for paid plans. Gemini told them it couldn't send email directly.

Work out how to remove and repair a 1980s dishwasher from its model number with ChatGPT

A hired contractor couldn't work out how to remove the poster's grandparents' 1980s dishwasher, which was attached at the top. Hacker News user MattGaiser gave ChatGPT the model number; it explained why it wouldn't come out (a part had to be disconnected), found a replacement part and gave step-by-step instructions for taking that part out. They didn't end up buying the new part.

Skip a likely upsell on a Jeep's $1,800 service estimate after checking it with ChatGPT

At a Jeep dealership for a broken soft top, TikTok creator Debra was quoted $1,800 for an 80,000-mile service when they expected about $1,000. They asked for a printout, went outside and talked it through with ChatGPT, which told them the rear differential service was probably an upsell unless they towed heavy loads. They say skipping it saved $400. Motor1 notes the service is generally recommended every 30,000–60,000 miles and that experts say delaying it could cause problems later.

Recreate copycat Chick-fil-A nuggets with ChatGPT (it missed the breading)

Tom's Guide's Amanda Caswell asked ChatGPT for the closest possible homemade Chick-fil-A nuggets recipe and used ChatGPT Voice to guide them while cooking; it kept saying they were on track. After one bite they realized it had skipped the most important part, the breading: top-rated copycat recipes specify things like Ritz crackers, sugar and baking soda. With no time to restart at about 8:15 p.m., they turned the chicken into a makeshift chicken parmesan.

Pick a new area, build a moving checklist and budget, and plan the interior with ChatGPT and Gemini

A product manager says a friend moving house used ChatGPT to rank areas by commute, local shops and safety before choosing a place, then Gemini to build a moving checklist and rough budget in Google Sheets, then ChatGPT image generation for interior design ideas. The friend, who doesn't work in tech, said it was easier than expected.

Lower an electricity bill with ChatGPT's energy-saving tips

Tom's Guide's Elton Jones told ChatGPT they paid a $230+ monthly energy bill and asked for tips to lower it. It pointed to repeated heater and air-conditioning use as a big driver; after changing habits such as fully turning off their consoles and installing LED bulbs, they say their Con Edison bill came to $130+ instead of $230+.

Search for a wedding venue with ChatGPT's Bridebook app (it couldn't beat their own search)

A few months before their wedding, TechRadar's Hamish Hector tested Bridebook's ChatGPT integration with the venue brief they and their fiancée had used. Several venue costs were wrong compared with quotes they'd received, and they found it no more useful than scrolling Bridebook or Google, in some ways less, because its results were more restrictive.

Double-check a CPA-prepared draft tax return with ChatGPT and Claude and find two errors worth $2,686

Before filing, Katie Kormanik ran a CPA-prepared draft tax return and all of their 2025 tax documents through both ChatGPT and Claude. Both found the same two errors, which once corrected will save them $2,686.

Ask ChatGPT whether a Schengen visa biometrics waiver applies, and miss the renewed-passport catch

A client applying for an Austrian Schengen visa asked ChatGPT whether biometrics were mandatory. It said they can be waived if you've had a Schengen visa in the last five years, allowing a third party to submit. Visa professional Chandan Pandey noticed the client's previous visa was in an old passport, and the waiver requires it to be in the current one. Pandey refused to submit it on the client's behalf; the client went for biometrics in person and confirmed the rule. Pandey says relying on ChatGPT's answer would have meant a rejected application.

Plan a twins' birthday party for 40 kids with ChatGPT and Claude head-to-head, from theme to RSVP tracking

For their soon-to-be seven-year-old twins' party, Clifford Parker gave ChatGPT and Claude the same brief and budget over four rounds. Claude asked three questions first and produced a Minecraft sports day with a run sheet, prep list and budget tracker; ChatGPT found a local venue and entertainer with a phone number and booking script; ChatGPT's image generator won on invitations; and Claude, connected to Parker's computer, updated the RSVP spreadsheet from a phone message. It finished 2–2, with ChatGPT winning the tiebreaker.

Lower a phone bill by $80 a month with a script from ChatGPT

A poster uploaded their cell phone bill to ChatGPT and asked how it could save them money or whether another provider offered the same service for less. It gave them a script covering what they were overpaying for; they called T-Mobile, followed it and say their bill dropped by $80, about $960 a year, for under 5 minutes of their time.

Handle an eBay buyer's 'not as described' partial-refund demand with ChatGPT

On a $500 eBay sale, an overseas buyer asked for a big partial refund, then said the box wasn't factory sealed and sent photos of a scratch. The seller asked ChatGPT what an experienced seller would do; it said don't argue, don't offer a discount, and tell the buyer to open a return through eBay. Because the order used eBay's international shipping program, eBay handled it: the buyer was refunded, the item wasn't returned, and the seller says they kept the money.

Lay out what was paid and owed in a vendor billing dispute with ChatGPT (it invented invoice numbers)

A business owner fed ChatGPT all of the payment history, invoices and email threads from a vendor billing misunderstanding and asked it to set out exactly what had been paid and what was still owed. Five seconds before sending the email, they spot-checked a couple of invoice numbers and found the numbers were all made up: they looked real and had the right format, but none existed. They didn't send it.

Make a Costco weekly grocery list for under $100 with ChatGPT (real prices came to $167)

GOBankingRates' Kathryn Jackson asked ChatGPT for a full Costco shopping list for the week under $100; it said the list was for a family of two and totalled $95. On Costco's website the same groceries came to $167, some items only came in larger quantities, and the list left out dairy like milk and cheese, tomatoes, other green vegetables, potatoes and other meats.

Build a tiny house with no experience using ChatGPT for quantities, purchase order and cost-splitting, while catching frequent errors

With no building experience, Simone Solazzo and Anne Leijdekkers built a tiny home in the Netherlands over five months in 2025, asking ChatGPT questions constantly. It helped them think through deviations from the plan, do sums and measurements, work out quantities and buying order for around 250 items, and split costs between them. But they often doubted its guidance, and an architect friend showed its answers were frequently wrong; sometimes it stated false things when it didn't know. They relied on the friend and family for ventilation, insulation, electricity and water.

Help a sixth grader learn to factor with Grok and ChatGPT as 'the greatest math teacher'

A parent photographed their daughter's sixth-grade worksheet and asked both Grok and ChatGPT to act as the greatest sixth-grade math teacher and explain to a 12-year-old how to factor each equation using the greatest common factor, with clear steps and ways to check their work. They say both of them now know how to do it, and the daughter did the rest of the worksheet without AI.
