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.

Sort a year of bank transactions for a freelancer's tax filing with Gemini, Claude and Lumo

XDA's Megan Ellis, a freelancer who files taxes three times a year, gave the same bank and credit-card exports and prompts to the free plans of Lumo, Gemini and Claude. Lumo missed a month of medication payments and about a third of the income. Gemini made no obvious errors and came within $100 of the manual income total. Claude hit its usage limit within two prompts at peak times but was the only one to match the manually filtered income total. Ellis still plans to do most of the taxes by hand.

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.

Prepare a tiered question list for a specialist call with Claude

Before a call with their wife's neuroendocrinologist, a poster gave Claude their clinical context and asked for a structured appointment prep. They say it organised questions into three tiers (what changes next steps, understanding the mechanism, and forward-looking), each with a note on why they're asking, so they could triage if time ran short. They shared a reusable template and say the goal is to be prepared, not to replace the doctor.

Find a failed AC contactor and fix it for $15 with Claude's step-by-step troubleshooting

When their thermostat rebooted every time the AC tried to start, a homeowner worked through it with Claude: checking thermostat wiring, then the air handler board and fuse, then isolating the cooling circuit, which pointed to the outdoor unit. There they found a contactor with degraded coil wiring, ordered a $15 replacement and swapped it in 20 minutes. They say the AC runs perfectly, versus a $150 minimum service call they expected to reach $300–400.

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.

Turn a handwritten family pie recipe into an infographic with Gemini and ChatGPT (it garbled the recipe)

A TechRadar writer photographed their mother's 30-year-old handwritten apple pie recipe and asked Gemini and ChatGPT to turn it into a clear, cartoon-style infographic. Gemini's version was cute but full of misspellings and nonsense like 'Dash nutamon' and a cheese grater, and corrections didn't fix it; ChatGPT did marginally better but left out details. Claude gave the clearest, if plain, recreation. They called Gemini's first try unusable and kept their paper original.

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'.

Check whether a noisy dishwasher is failing from a recording with Claude

A Hacker News commenter noticed a loud dishwasher at an old apartment and, unsure whether to call a technician, recorded the noise, screenshotted a spectrogram (a picture of the sound) from an app, took photos and gave them to Claude. The commenter says it matched frequencies to the machine's components and concluded it was operating normally, with the pump just louder from age and wear. A reply asked how they could know Claude was right without verifying.

File a utility complaint about low voltage with Claude

A Hacker News commenter who had circuit-level power monitoring set up at home was analyzing bills when they mentioned voltage problems to Claude. They say it put together a packet documenting brownouts down to 95v and routine dips below 110v, and helped them fill out a Board of Public Utilities complaint form. Two days later the utility, JCP&L, called; they say they still need to call back to ask for a larger transformer.

Organize a Spanish visa renewal and fill the forms with Claude and Claude in Chrome

For a Spanish visa renewal, the poster set up a bureaucracy folder with Claude, fed in the family's information, had Claude verify documents, then used Claude in Chrome to fill the online forms faster and more accurately than checking by hand.
