- Redline a vendor's standard OEM agreement with Claude for the first three rounds, then have a lawyer do the final checkRecreated promptEvidence: Described by poster
jedberg regularly negotiates OEM agreements with vendors that mostly use the same template and draw the same objections. They tried Claude first, and their lawyer was impressed that it found things the lawyer had missed. jedberg then used Claude to redline that type of contract, and the other side remarked that the lawyer had been surprisingly thorough. The lawyer did the final check and by then basically said it looked good, and jedberg saved a lot of money by doing the first three rounds with Claude.

badlibrarian runs a business and sometimes buys things on Amazon. At tax time they used to search for the big business items and categorise them in QuickBooks Online until they gave up, using a janky browser plugin and two monitors full of Excel windows. Now Claude does it and doesn't give up, despite QuickBooks being slow. It will even click 19 times to split a transaction because they'd put a router and shampoo in the same Amazon cart one night in February 2025.

- Send four AI agents to get real car insurance quotes: Gemini and ChatGPT got none, Claude and Muse got five eachRecreated promptEvidence: Described by poster
Thy Toeung needed to review their car insurance before their son turned 16. They made a data sheet listing every driver, vehicle and the cover they wanted, and asked Claude, ChatGPT, Gemini and Muse to act as their insurance-shopping agent and get real quotes from six reputable insurers. Gemini's auto-browse explained it couldn't use the websites and handed back a comparison table to fill in. ChatGPT took 2 hours and 279 messages across 12 attempts and got no quotes; Toeung believes sites such as Allstate, Nationwide and Liberty Mutual block AI agents. Claude ran for 3.3 hours and got 5 real quotes. Muse, on its free tier, used several sub-agents and got 5 quotes in about 20 minutes. Toeung switched insurer and got about twice the cover for around 40% of the previous price.

- Track 186 applications, find missing keywords and review interview notes with Claude to land an offerEvidence: Article or interview
Margareth Felicia Gono, an international student who needed a visa, started job hunting scattershot. Gono built an application tracker with Claude, had it pull the main skills and keywords from each job description and compare them with the résumé, and used it as a career coach, which led to three résumés for analytics, sales and marketing, and consulting. Where interviewers allowed recording, Gono ran sentiment analysis on the notes to see where Gono hesitated or used filler words. The tracker showed 186 applications, 44 cold outreaches, 19 interviews, six take-home assignments, three final rounds and one offer, as a senior associate at DoorDash.

thobes and their spouse took in a scared stray cat found in Elysian Park on July 4th. Weeks later the cat stopped eating and declined fast; after-hours ER care in LA cost $7,500 for two days of life support before any diagnosis, and treatment moved to a clinic in Tijuana. thobes ran each batch of test results through Claude, which kept saying to look into FIP and to push the vet to test the stomach fluid for it, though the first vet waved it off. When the Tijuana clinic was asked for the extra FIP test they first refused ('AI is not a vet'), then agreed. It came back positive, the cat got a prescription and is expected to live. thobes says not to trust medical decisions to AI entirely.

tonyarkles was curious about astrophotography and had a budget to fill any gaps in their existing photography kit. Claude's conclusion was to get a $20 intervalometer and a battery adapter that runs off the wall: the lenses and tripod they already had were fine. It also pointed out that Jupiter and Venus were near conjunction, so a dark spot facing west would give a good timelapse that weekend, and later gave rough guidelines for a partial lunar eclipse that produced some amazing photos. tonyarkles now plans to spend the budget on a proper mount, but only after confirming they enjoy the hobby.

idopmstuff runs several small consumer brands. For the most recent one they acquired, customers got in touch through Facebook and Instagram comments and messages as well as email, so they had Claude build an app that pulls those messages in as they arrive and drafts a reply, including any actions needed, for them to edit or send. Their edits feed back into its playbook, and it has got pretty good. It handles warranty claims (ask for a photo of the damage and the order number, create a replacement order, email a confirmation) and most common questions. Every reply is still approved by a human, though they plan to let it handle common cases on its own soon.

Iliyana Stareva had three weeks to move a family of four from Spain back to the Netherlands. They opened a Claude project called "Move Back to the Netherlands", gave it their history, details about their kids and what was already sorted (they still had Dutch bank accounts and a phone number), and asked for a full plan covering housing, schools and childcare, moving both cars, taxes and municipality paperwork. In five minutes the plan surfaced a few things they had forgotten. Claude then built a tracker in Notion with owner, deadline and category for each task plus a "this week" view, and put key dates into Google Calendar, including a call to the municipality. Some items didn't apply and some deadlines moved once checked against their work calendar, so they spent ten more minutes adjusting it.

After two pet insurance policies lapsed, Dimitri Sudomoin was billed $359 in 'earned premium' and spent two months being threatened with collections. Weeks of emails with the insurer's customer team got nowhere and a supervisor closed the thread saying they had gone as far as they could. With Claude planning the campaign, Sudomoin filed a complaint with the insurer's home-state regulator in New York and emailed two of its executives. The insurer folded in three and a half hours: the bill was settled at $118 as a 'special exception', with a written promise that nothing ever went to a credit bureau.

Dimitri Sudomoin's $1,166 robot mop failed under warranty. After eleven weeks of 'forwarding this to our technical team', the company refused to honour the warranty and offered a final 46% partial refund. Claude's first idea, a federal warranty law angle, looked weak, but reading the terms of service it found the company's own arbitration clause: under the rules of the forum the company picked, Sudomoin's filing cost was capped at $250 and the company would bear the rest of the fees. Three days after Sudomoin filed, the company offered the exchange it had previously refused. Sudomoin describes this one as still in play.

Two months after a water pipe burst in their house, wellpast is using Claude to run their side of the claim with a large insurer. It reads the policy, organises and files scans of receipts for additional living expenses (ALE), reads and flags messages from the agents, logs all correspondence, work estimates and invoices, points out when the insurer is delaying or not keeping promises, and challenges coverage decisions based on the policy. The adjuster gets very tidy, documented receipts and logs. The delays have been bad enough that Claude now insists they should file a complaint with the state insurance department. Without Claude, they say, they'd probably have given up from fatigue.

Sarah Silbert was using Claude to choose checked luggage for a trip to Germany and asked, almost as an afterthought, what else needed doing before the trip. Among the obvious items, Claude said to check the passport had three months of validity past the return date. It didn't: it expired about two months after the return flight, one month short, five days before departure. Inside the 14-day window for an urgent passport agency appointment, Silbert got a slot the next day, paid the $60 expedite fee and picked up a new passport the following day, using the State Department website as the official source.

Natasha Hsi got five homeowner's insurance quotes for a complicated house. They differed on exclusions, wind and named-storm deductibles, and admitted versus surplus-lines insurers, and Hsi found them hard to follow. They fed all five plus their current renewal into ChatGPT and Claude and ran scenarios such as a hurricane loss and a total loss. When Hsi suggested starting with BBB ratings, both pushed back: BBB tracks complaints, while financial strength ratings show whether an insurer can pay after a storm. Hsi took the questions back to their original agent, who returned a better-structured quote at a more reasonable cost with none of the weakly rated insurers.

Their accountant said it would actually cost more, because of how New York City taxes S Corps. They hadn't told Claude they lived in NYC, because it didn't occur to them that it mattered. Their takeaway: tax questions are full of details like this, often subtler than where you live.

To claim expenses, they photographed the receipts for clothes bought during those 10 days and asked Claude to build an Excel sheet from them to attach to the claim. It saved a lot of time, but WestJet paid only 60% of the original claim.

Hally Peck, a chief marketing officer in New York with two kids and a husband who also works full-time, used to schedule life only days or a week ahead. Peck gave Claude the kids' school calendars for the year, with holidays, vacations and parent-teacher conference dates, and had it add them to the family calendar and cross-check school events against existing plans. It flagged a few conflicts with work trips already booked. Catching them months in advance rather than days or weeks means the family can resolve or plan around them.

DANN's pain started out of nowhere on a Friday night and within twenty minutes they could barely walk; the plan was to take painkillers and sleep it off. They asked Claude first, and it said this could be testicular torsion, that there's a 4 to 6 hour window, to go to the ER now, not to eat or drink in case of surgery and not to drive themselves. They went. The first ER untwisted it and sent them home; at 3am the pain came back and after a second visit they were taken by ambulance to a bigger hospital, staying three days. Torsion was never confirmed because it was untwisted before an ultrasound, but DANN is home, healing and kept everything.

pugio and their spouse were sleep-training their baby, who wakes a few times a night and either babbles back to sleep or fusses for 10 minutes before a parent needs to go in. With a spare esp32-box-3 and a few rounds with Claude, they built a baby monitor that tracks how long the baby cries or fusses, streams audio only after 10 minutes, and sends notifications at 30 seconds and at 10 minutes. The log shows the baby often wakes 1-2 times a night and resettles almost immediately, and the parents only wake when the audio comes through. During the day it tells them when naps end.

- Get a commercial cooler that kept cutting out working again for about $30 in parts, troubleshooting with ClaudeEvidence: Described by poster
Jassy's homestead relies on a commercial glass-door cooler for garden harvest, eggs and bacon mid-cure, but it had sat broken for 8 months because a repair call would cost $600 or more. Jassy described the symptoms to Claude: it cooled for 24–48 hours, then cut out while the fan kept running, with no icing. Claude came back with six things to check, saying which were reasonable DIY jobs. It suggested cleaning the coils. After that, Jassy reported that the fan ran and they could hear it calling for the condenser but the condenser did nothing. Claude was then fairly confident it was a bad start relay or overload protector, about $15 each. Jassy replaced both themselves, the cooler cooled almost immediately and had held steady for a month. Parts were about $30 with shipping.

Jassy's Whirlpool Duet washer had been run without the water turned on, and got stuck in a door-fault loop: pump running, door locked, lights flashing, and no way to reset it or turn it off. Local technicians charge a $300 minimum just to show up. The first couple of reset sequences Claude suggested didn't work, but Jassy kept describing what was happening and then shared a photo of the control panel. Claude then recommended holding the cancel button for a full 3 seconds (which, Jassy notes, is printed on the panel), and the washer reset and finished its cycle. The fix cost nothing.

Two years after an ER visit, Jackie Davalos got a collections notice saying $22,604 was owed to the hospital, having never received a bill; the records wrongly listed Davalos as uninsured. A first dispute only removed one medication charge. Davalos's partner, Walter Kerr, uploaded the billing and medical records to Claude and asked whether they had any further recourse. Claude suggested several arguments, including that legal requirements on debt and insurance might not have been met. Using many of them, Kerr wrote to executives at the hospital and its parent company, and shortly after the hospital waived the entire bill, later acknowledging a clerical error. A legal aid lawyer who reviewed it said some of Claude's analysis was right but it misunderstood some of the laws it cited.

- Check whether a half-hourly electricity tariff would be cheaper by giving Claude 87 days of smart meter readingsRecreated promptEvidence: Screenshots or logs
Beckie Brown's household was on a fixed Octopus Energy tariff at 26.90p per kWh and wondered about switching to Agile, whose price changes every half hour. They downloaded 87 days of half-hourly smart meter readings, Octopus's published historical Agile prices for their region and their own tariff details, and asked Claude to work it out from the real data. In about 30 minutes Claude matched usage to prices, projected a full year from three years of Agile history, and produced an 8-page report: about £171 a year saved with no changes, around £218 with small habit shifts, a peak penalty of about £133 from 4 to 7 pm, and no exit fee. They switched. In a follow-up post on 12 May 2026, the first 30-day bill was just under £78, against about £120 for the same usage on the old tariff, in a record month for negative prices.
