He built a workflow that connects to their bank accounts and credit cards through Plaid and emails him and his wife a budget update three times a week, showing how they are tracking against the budget, with spending analysis and suggestions for cheaper alternatives.
Carlos Diaz, host of the Silicon Carne tech podcast, said on social media: 'I saved $2,300 this weekend, in just an hour and a half.' Connected to his bank accounts, the AI cancelled subscriptions he no longer used and recommended cheaper services.
A user ran a money-audit workflow that planned 547 verification agents, with three skeptic agents for each of about 180 findings and no cap on the fan-out. About 180 agents ran, using roughly 36.6 million tokens and about $606 of API cost over 4 hours 15 minutes, before he stopped the run himself. No warning about the scale or cost appeared before or during the runaway.

Karol says she asked her AI 'Hedwig' to audit her forgotten subscriptions. Screen recordings show a 'Subscription Before and After' dashboard dated Oct 11, 2026: recurring charges cut from 22 to 5, and monthly cost from $149.11+ to $58.73+ — about $90 a month saved — after which she lists the services she deliberately kept.
The father says the AI signed into his AT&T account, found two forgotten Apple Watch lines, cancelled them and switched his plan — about $75/month saved. He says he never opened a settings page himself.
DaVe McComb's screenshot shows his AI 'Archer' reporting a loyalty-chat win: Verizon offered 25% off plan charges — about $33.75/month for 12 months, no plan change or contract — which, with a hotspot already cut, drops his bill from $194.74 to about $161/month, roughly $405 a year. Archer asked whether to accept; he replied 'Yes, take the discount', and Archer confirmed it had told Verizon to apply it and would verify.
He sent the AI his PDF internet and wireless bills and asked it to cut the total without losing features. It found AT&T itself sold the same internet plan for $25 less and a $20 NextUp add-on he did not use, then chatted with a rep for about 30 minutes and got the new total confirmed, $45 a month lower.
A screenshot of the AT&T app's bill history shows three periods: $116.08 (Jul–Aug), $116.08 (Aug–Sep), and $41.70 (Sep–Oct), labeled '$74.38 lower than your previous bill.' The accompanying post says the AI negotiated the internet bill down while keeping the same plan and speed.
A user runs an AI named Reaper against his credit card debt: the balance went from $8,400 to $7,912 by day six, with daily progress reports from the bot. The paydown is small, tracked and reported like a coach with a ledger.
CData's Dot pulled monthly invoiced totals from Xero for one business unit and QuickBooks Online for the other, checked currencies and invoice statuses matched, and returned one combined table for November 2025 to August 2026. March 2026 was strongest at $28,000 combined; the post notes the test account held demo data.
