Re-learn high school maths with quizzes and a study guide in Gemini Guided Learning

An XDA writer used Gemini's free Guided Learning mode to retake high school maths and history after two decades: it built 10-question multiple-choice quizzes, explained wrong answers, reviewed their weak spots and produced a study guide they turned into a Google Doc. They say a few sessions rebuilt their knowledge, and they also used it to learn food-ordering phrases for Paris, but they don't see it replacing a teacher.

Find extra tax refund money with Grok's help

A poster says they asked Grok to help with their taxes and it helped them get around $1,500 more on their tax return, adding that it also helped them learn about taxes they were never taught.

Get a dog with sudden foamy coughing to an emergency vet in time after ChatGPT flagged possible bloat

When the family dog began coughing up foam after drinking, Chase Williams asked ChatGPT to question them like a vet would. After asking about breed, age, frequency and when it started, ChatGPT said it could be urgent and might be bloat, which in bigger dogs can be fatal within hours. The dog was put in the car immediately; the vet diagnosed bloat needing emergency surgery and said the dog had arrived just in time. Williams stresses ChatGPT is not a vet and shouldn't be trusted on its own.

Make sense of dealership lease printouts mid-visit with ChatGPT

A first-time car shopper who found the dealer's math confusing asked for a minute alone, took screenshots of the printouts, gave ChatGPT some context and asked how to negotiate and which options were right for their family. They say it explained the pros and cons clearly and told them what to negotiate; they followed about 90% of its advice, said 'no' about 4 times to 'meet in the middle' offers, and leased the car on their terms.

Plan a fun, free weekend with a 3-year-old with Gemini

Away for Canada's February long weekend, Android Police's Jade Lassalle wanted a fun-filled plan for their partner and 3-year-old daughter. 'Help me plan my weekend' got clarifying questions and vibe options; 'Help me plan a fun weekend with my 3-year-old' gave much better results. They found Google Maps searches for things to do in Hamilton showed mostly restaurants and shopping, not the fun and free ideas they wanted.

Cut a $195,628 uninsured ER bill to about $32,500 by checking it against Medicare rules with Claude

After a relative died following four hours of emergency care, Matt Rosenberg got the hospital's coded UB-04 form and asked Claude to compare each charge with what Medicare would pay. Claude spotted unbundled stent supplies worth over $100,000, a bypass charge for surgery that never happened, and ventilation billed alongside critical care, and estimated Medicare would have paid about $28,675. Rosenberg had ChatGPT check the analysis, spot-checked the rules, and sent a six-page letter. The hospital countered at $36,356 and they settled at roughly $32,500.

Load a child's soccer schedule onto the family calendar with 2-hour blocks using Gemini

A parent screenshotted their son's soccer schedule, uploaded it to Gemini, asked it to create events with a 2-hour window and told it which family calendar to use. They say two minutes later every game was on the family calendar, saving about 15 minutes of manual entry.

Fix a washing machine that won't fill using Gemini, after ChatGPT picked the wrong part

A poster described their broken washing machine to Gemini, which helped them run diagnostics, found it wasn't taking in water and pointed to the inlet valve. They used ChatGPT's shopping help to find and order the part, but the first part didn't fit even though ChatGPT said it would. They installed the right one with Gemini's guidance in about 1.5 hours total, saving about $120 on labour.

Plan a week of less starch-heavy meals around local foods and budget with Gemini

Android Police's Irene Okpanachi, whose diet was mostly starch, asked Gemini to act as a nutrition coach, held its questions until a 'READY' safe word, and described habits, local foods and budget. After revisions to swap out foods that weren't affordable or easy to find, Gemini's plan moved most starch to lunch, kept breakfast and dinner lighter and more protein-forward, and set simple rules such as a fist-sized starch portion and eating vegetables and protein first.

Build a biweekly grocery list on a $175 budget with Gemini

Tom's Guide's Elton Jones gave Gemini and ChatGPT the same prompt: a $175 biweekly grocery budget, the foods they usually buy, and a request for a categorized, priced table. Gemini said $175 over two weeks was realistic if they balanced splurges like steak and shrimp with rice and potatoes, and gave a table by category, item, quantity and estimated cost with a total. ChatGPT's similar chart added items they don't usually buy, like eggs and shredded cheese. They picked Gemini as the better financial adviser overall.

Use Gemini as a job-search co-worker after a layoff: resume, cover letters, outreach and interview prep

The day their role was eliminated, a poster started using Gemini as a full-time job-search co-worker. Over three weeks and more than 40 hours, they say it helped them optimise their LinkedIn profile, update their resume, write custom cover letters, networking messages and recruiter follow-ups, and prepare for interviews. They review and challenge everything it produces.

Turn a school-year calendar into draft Google Calendar events with Gemini

Instead of typing in the kids' school calendar for the next school year, Joshua Kaan gave Gemini the details. Gemini drafted the events and Kaan approved them. The one thing it couldn't do was add other people's email addresses as guests on the events.

Appeal a denied cardiac test using studies found with ChatGPT Deep Research

When insurance denied the poster's husband's cardiologist-ordered nuclear stress test as 'experimental' (a $1,500 out-of-pocket cost), the poster used ChatGPT Deep Research to find peer-reviewed studies on the test's effectiveness: five studies in ten minutes. Five minutes later they had a draft appeal letter for the cardiologist to review and send. The poster says a week later the insurer reversed its decision and covered the test.

Tailor a resume, cover letter and LinkedIn summary with ChatGPT, then get Gemini to judge them

A writer fed ChatGPT a job description and their existing application details to produce a tailored resume (two attempts; the first looked too plain), a one-page cover letter and a LinkedIn summary with recruiter keywords. They then asked Gemini to play the hiring manager: it scored them 8.5 out of 10 with 'a very high probability of landing an interview', but said the documents were too 'tech-first' rather than 'finance-first' for this employer.

Narrow down why a gas dryer takes three hours with a ChatGPT video chat before calling a repair company

When a dryer took three hours to dry a load (normally 45 minutes), Lisa-Anne Chung showed ChatGPT the model number, the parts that weren't working and the pipes at the back over a video chat. It identified the model from a photo, walked Chung through checks such as whether the burner glowed and listening for clicks, gave a shortlist of likely causes, and suggested Sunnyvale repair companies via Yelp with a fair diagnostic fee. Chung says they had a solid hypothesis in about 10 minutes and could talk knowledgeably when they called a repair company.

Diagnose a broken garage door opener and replace the carriage for $22.48 with Gemini

A homeowner described their garage door opener's behaviour to Gemini, which identified a failed carriage, pointed them to where to buy a new one and found a DIY installation video. They say they spent ten minutes with Gemini and $22.48, versus a service call and repair they estimate would have cost several hundred dollars.

Build a shared household inventory of bills, policies and subscriptions from Gmail with a Gemini prompt

Nick Malham shares a Gemini prompt for turning six months of Gmail into one shared Google Sheet of household admin: insurances, banking and home loan, utilities, car cover, phone and internet, subscriptions, and will and power of attorney, with company, cover type, who it's for, account number, cost and frequency, payment type and key phone numbers. Malham suggests connecting Gemini to Google Workspace first, and checking a 12-month bank export for anything that never reached the inbox.

Figure out why a car suddenly won't go over 19 mph from a dashboard photo with ChatGPT

On a dark, rainy drive, TechRadar's Graham Barlow's second-hand car would only crawl and the dash showed '19 mph limit'. They photographed the dashboard and asked ChatGPT; it said a speed limiter was switched on at 19 mph and was probably controlled by a button on a stalk behind the wheel. They found the button labelled 'Limit', turned it off and drove on without calling roadside recovery.

Pick a breed, name, shopping list and care plan for a first family puppy with Gemini

Planning a first dog with their son, Allison Marx used mostly Gemini to recommend breeds that suited their lifestyle and requirements (they chose a Havanese), come up with a name (Chip), build a shopping list and draft a care plan. Two weeks after bringing Chip home, Marx says the family couldn't be happier.

Check a 'take-home task' repo from a job offer for malware with ChatGPT before running it

A developer offered a 'unicorn' job taking over a software project was asked to review and run the company's GitHub repository. Instead of cloning or running it, they asked ChatGPT to analyze it, and say it found hidden malware in what looked like a harmless library file, built to connect to an outside server and steal files, keys and credentials when the project was started. They call it a common scam aimed at job seekers.

Clear a car's no-start service code caused by a slightly open window with Grok

After leaving the driver's window about 1/4" open for roughly 36 hours, a poster's car wouldn't start and they jump-started it with a portable charger; the service manual pointed them to the dealer. The poster says Grok quickly found there's a dash service code for the driver window and the fix was to roll the window down and back up, which cleared the code and saved a dealer trip.

Build an interactive kids' chore tracker that unlocks weekend screen time with Gemini

After two weeks of the kids home for the holidays, Liam Darmody used Gemini to create a master tracking sheet for chores, replacing fridge lists that never stuck. Each day a child completes all tasks, a green progress bar unlocks 20% of their weekend iPad time; hitting all five days unlocks a badge and all of their weekend iPad time. Gemini worked out formulas Darmody says were more complex than anything they could have written, and also gave a prompt for prototyping an app.

Fix a dead freezer with a £10 wire after Grok's voice-and-camera mode found a known fault

When a freezer stopped working, Marc Landers gave Grok the make, model and problem. Grok had them turn on voice and camera mode, open the door, remove the top hinge cover (no tools needed) and point the camera at a wire it said was a known fault for that model. Grok gave the price and an Amazon link for the part; the £10 wire arrived next day and took five minutes to replace, instead of paying a repair technician.

Get a faulty demo car replaced under South Africa's Consumer Protection Act with Grok's help

Two days after buying a demo Chery Tiggo 4 Pro, the tyre-pressure monitoring system failed at 120 km/h. The poster (@viking_boer) used South Africa's Consumer Protection Act and Grok's step-by-step advice to reject the car. The dealership resisted, but within two weeks the poster got a brand-new replacement, with the leather seats swapped over.
