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.

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.

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.
