When it didn’t work, and how to avoid the same mistake · 971 ideasResearch five competitors into a structured report in 15 minutes
Reviewers tasked the AI with researching the top five competitors in the freelance project-management space across 12+ websites including G2, Capterra and Reddit, extracting pricing, audiences, features and common complaints. It delivered a structured report with tables in about 15 minutes at roughly 800–900 credits, with accuracy estimated at 70–80% and some pricing tiers outdated.

Assemble my tax documents from email and portals, 90% done from one prompt
Bill D'Alessandro gave the AI one prompt: compare last year's tax folder and return against this year's documents, pull whatever is missing from his email and financial portals, and save it all to Google Drive for his accountant. It got about 90% of the way there.

Trade $50 of real money for a week and report honestly
A developer handed the AI $50 of real money on Alpaca for a week (24 September to 1 October) plus $10,000 paper accounts in stocks and crypto, with rules to research first, sell daily and flatten by Friday. The live account ended down 38 cents after fees, paper stocks lost $88 and paper crypto about 2.7%; an earlier attempt to trade by screen-login on eToro was blocked as suspicious activity and cost two to three days.

Find my cheapest NYC to Tunis flights for October 26
Moneywise journalist AnnaMarie Houlis gave the AI her parameters: any NYC-area airport, after 5 p.m. on Oct. 26, carry-on only. The AI returned a reasoned lineup: its pick, a $595 Turkish Airlines flight from JFK (8:40 p.m., 14h45m); the cheapest, a $462 Royal Air Maroc with a 33-hour Casablanca layover; and the fastest, a $725 Air France from Newark (10h45m). She kept the research but booked herself, unwilling to share card details after reported the AI security vulnerabilities.

The AI could not reformat my Excel file. I lost two hours.
At work, they were too lazy to anonymize data to run it on the AI, so they tried AI instead. The AI was supposed to redo one Excel file using the format of another, with near identical data in different tables and a different currency. Two hours were lost.

The AI built my insurance appeal package and my doctor used its letter
When her employer's plan stopped covering her medication, the AI worked out that the plan had a continuation of therapy route and built a full appeal package for her to hand in, arguing the drug was a continuation rather than a new request. She filed it, and her doctor used the letter template it wrote.

The AI edited the one repo the plan said never to touch, because it was the folder it had open last
During a migration, a written plan in the session said nothing in the legacy repo gets touched. The plan was re-shown in full mid-session. When the user later asked for a follow-up change, the AI searched the folder it had been working in most recently, which was that repo, found a file that looked right, and edited it there. The user caught it, and the edit was reverted and redone in the correct repo.

An overnight video batch used the wrong model and spent $2,500
A video maker asked the AI to run a batch job overnight: variations on one shot so he could pick a composition in the morning. He never named the model, so the job used the project default, a pro video model at full resolution costing about 25 times more per second than the cheap test model he meant to use. Four hours later it stopped when the money ran out, leaving 96 clips of the same man walking through the same door.
