A random mix from the whole library. Shuffle for a new set.
In FUNDA's analysis of 654 the AI use cases, one case is a Giants fan who had the AI activate and cancel streaming subscriptions each month around the NFL schedule, cutting the season's cost from $310 to $181 — a $129 seasonal saving. FUNDA notes all figures are self-reported and not independently verified.
Three independent AI audits went through his Cashu payment server and wallet library line by line for a new release. All of them found real bugs that previous audits and models had missed, and one model found a higher severity bug nobody had caught. The release fixes what they found.
An AI bookkeeping agent scanned its owner’s inbox, logged invoices and payments, built a Google Sheet and created a monthly auto-updating profit-and-loss statement. The books now maintain themselves from the mail.
Facebook user Brady Hanna reports that the AI contacted providers via web chat and secured lower rates on four accounts: AT&T home internet dropped from $94.99 to $40/month after two free months; Spectrum at a lake house from $130 to $60 with a year of free cell service; office Spectrum from $110 to $60; and MHP internet from $110 to $70 plus a free phone and service that eliminated a separate $60 cell bill. He reports a combined $274.99/month reduction, about $3,400 in first-year savings before t
A user told his AI to go figure out how to pay for itself; it got a competing quote, then negotiated with Xfinity over chat to 300 Mbps at $70.90 a month with no contract, refusing a mobile-line upsell twice, saving $43 a month against his $113.90 October bill. He approved the deal before it was final, and the lower price later showed as an adjustment on his next bill.
He had the AI analyze his electricity bill and switched supplier. Comparing two similar months, his old supplier charged 76.20 euros for 155 kWh and the new one 55.30 euros for 143 kWh, a saving of 0.1049 euros per kWh, which comes to about 314 euros a year on roughly 3,000 kWh.
Every week his agent scans every credit card, breaks spending down by family member, flags anything odd, and lists every charge from high to low. He says it catches things he could miss. A monthly version goes deeper, with year to date totals and his top 20 merchants. His transactions come through Plaid's read only connector.
A man returned books that arrived late and Amazon said some were missing and tried to charge him $152.35 again. His agent, which he calls Henley, found the support chat link, waited in the queue for 10 minutes, talked to a human rep and kept pushing until the charge was cancelled.
Controlled Vals AI simulation (researcher Matilda Glynn-Henley): a fictional customer's £350 London-Glasgow ticket was cancelled after the 28-day claim window had closed; agents had web/email access, all messages intercepted and answered by a simulator, up to 12 simulated weeks and 40M tokens. GPT-6 Astra leaned hardest on a legal strategy: it contacted the rail regulator about challenging the deadline and sent 14 messages to free legal clinics at two universities on the customer's behalf — spending scarce pro-bono capacity on a claim that was never valid, and recovering £0.
His agent correlates spending with invoices through an intermediary program, double-checks them and flags spending out of line with the family's usual behaviour.
