A random mix from the whole library. Shuffle for a new set.
A value investor had the AI recreate the spreadsheet he built by hand last year covering every warrant on the NYSE and Nasdaq. The AI looked up strike prices and redemption prices, wrote short company descriptions, and added Google Finance formulas for live prices. It took about 30 minutes of the AI time and 10 minutes of his.
She reports that after involving the AI in a dispute over a broken, irreplaceable piece of furniture, the company's refund rose from an initial $125 offer to $500 received.
The use-cases directory records someone having the AI monitor the Apple Store online and notify when an iPhone became available to pre-order — stock-watch automation for a launch.
A materials scientist with a PhD and almost no coding background built and shipped a live stock portfolio tracker over about three months and 277 commits, pasting code blocks the AI gave him into a terminal and pasting the results back. The tracker is not about returns: it makes him write down why he bought a stock and what would prove him wrong, then pressure tests his reasoning and scores how well his past calls held up.
Heather ('AI at Home with Heather') says she gave the AI access to her credit card statements to analyse spending and recommend better cards; it also flagged unused subscriptions. She cancelled a discount flight-alert service she no longer uses and downgraded Spotify Premium, for claimed savings of $675 a year found in about an hour — a figure she admits may be slightly exaggerated.
The AI negotiated a 25 percent reduction on the user's Verizon bill, worth roughly $405 a year.
The AI hooked to his Goodreads regularly scans local used bookstore inventory while he built a physical book collection for his family.
Sid Saladi, an early the AI user cited in the zachdoesAI setup guide's money-savings section, had the AI audit his recurring charges. It found a forgotten $9.54/month Google Cloud charge, filed for a refund, pushed back when support initially refused, and recovered $114.14 within five hours.
The someone Instagram carousel is a tutorial built on a real case: The AI got a $30 Xfinity 'Additional Usage' charge (130 GB at $10 per 50 GB) removed from an $81.50 itemized bill. Screenshots show the original bill and the reduced $50.86 balance after the courtesy credit.
He asked his AI for a pet hair robot vacuum under $500. Instead of a long written answer, it sent four cards he could compare, each with a price, a photo, battery life and a source.
