A random mix from the whole library. Shuffle for a new set.
Stanford EE student (310K followers, 'sage') documented upgrading her electronics lab by using AI (nicknamed 'Chef') to compare Facebook Marketplace listings under $200, identify a Hakko FX-888D in Los Angeles, message the seller directly, and negotiate the price down by $50. She picked up the boxed unit, unboxed it at her workbench, and thanked the AI on camera.
Had the AI install DuckDB and it is now running automated exports into DuckDB for his budgeting.
A man was paying about $30 a month to RocketMoney and the AI just to find subscriptions he had forgotten about, and using them only now and then. He had the AI connect to Plaid, where it found more subscriptions than the two apps ever had, and set up a weekly email listing his current subscriptions and any price changes.
He used AI to deal with a customer service agent about a cancellation fee he thought was unfair. The AI talked the agent into waiving the fee.
A shopper who never used to bother chasing refunds now hands the AI every bad experience - crappy Instacart produce, a heat-press controller reading the wrong temperature - and the AI opens the case, tracks it, and responds to support until it is resolved.
A Reddit poster set up the AI to trigger on every order/shipped email in Gmail: it opens each product page, compares the current price with what he paid, checks the store's price-drop policy window, and drafts a refund request without sending it. He notes most checks find nothing, but the ones that hit are money he would have missed.
Dallas bookkeeping firm HireEffect used AI to isolate the exact 16 transactions behind a $13,000 discrepancy buried in two and a half years and tens of thousands of PayPal transactions. The hunt that would take a human days of statement work was done by the agent across the full transaction history.
The AI checked a ResMed purchase against the maker's price guarantee three times a day, filed when the price dropped, and secured a $121 refund; a second claim for $81.40 is pending.
Built a purchase history scraper for Amazon and Kroger with price and quantity history views.
Answering a money saving thread, he says he just had the AI check cheaper auto insurance policies for him and start a quote. On the new policy he will save $650 a year. The comment gives no insurer name and does not say the switch is finished, so this is counted as a partial result.
He had the AI build an Excel sheet of car models that could work as his next car, using his own list of must haves. The sheet came back with 65 options, with size, comfort and whether each one comes as an automatic.
In a '3 things you didn't know you can do with AI' walkthrough, screen recordings show the AI searching Facebook Marketplace for a golf driver shaft, messaging the seller, and negotiating a Tour AD MT-6 from $160 down to $130.
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.
One the AI user posted that he keeps a dedicated bot whose only job is handling his Amazon returns. He flagged the setup as one to watch after Amazon began blocking the AI ordering.
Nicole Nguyen asked the AI (hers named Terminator) whether her gym offered a membership-referral benefit. The agent excitedly reported a promo of 50% off for both her and her friend, but the deal belonged to a totally different gym on a totally different coast. Her caption for the episode: even cuddly AIs can make mistakes.
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.
A man connected the AI to a Robinhood agent subaccount through its connector and gave it as much freedom as he could. It trades on its own and has made a small amount of money so far. He keeps the risk ring fenced in the subaccount rather than his main account.
One user listed what his AI did over a few weeks: filed his homestead exemption back to 2024 (about a $4,000 refund on the way plus roughly $2,000 a year), switched his car insurance to Progressive (about $1,500 a year), moved him to a cheaper power plan (about $800 a year), filed 20+ class-action claims for him and his wife (about $500 expected) and applied to 15+ jobs that led to interviews. He put the total at about $9,000, with forms prepared for his approval.
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.
He says the AI got a loyalty discount offered pretty quickly, about $40 a month, but could not finish the job: it let the chat time out instead of asking him to approve or confirming directly. Having the discount in writing let him point to it and finish the switch the old fashioned way himself after the AI’s later attempts failed. He still counts the $40 a month as saved.
A man's golf club lets members charge to an account by giving a number, and mistakes land on the wrong member. The AI built him a watcher that opens his club statement every morning at 8:20, spots new charges by their ticket numbers, and texts him each receipt with the running balance. In two months it caught a 25 dollar and a 115 dollar charge from other members that he would never have spotted.
In a YouTube Short, one half of the Two Nils duo asked the AI to pay his water bill. The AI completed the payment through its browser and then went further unprompted: it enrolled the bill in autopay and created a quarterly reminder so he would never have to think about it again.
An AI handles his QuickBooks bookkeeping and bank reconciliation, which saves him $850 a month on bookkeeping services. The same setup runs a first level helpdesk bot inside their support system.
Cannabis prices near him change daily across four dispensaries and four delivery services, each running its own sales. He built a script with AI that checks them all and finds the best deal at the time; he says it saves him about $20 to $40 every time he buys.
Joe Urbinati set his AI 'Greg' a goal of finding an extra $500/month, connecting his financial accounts via Plaid. Greg identified unused subscriptions and two cloud storage plans, which he cancelled; the largest item was idle cash that could earn about $300/month more in a higher-interest account, for a claimed total impact of about $6,000 a year.
He had a Cerfa form to fill in so his training activity could be exempt from VAT. He says the AI filled it in all by itself.
FUNDA reports that the most-viewed post in its 654-case the AI database is a phone-call story: a user had the AI negotiate with Comcast and streamline a mobile plan, saving more than $800 a year. The post drew 230,000 views.
An investor says the AI has updated several of his Google Sheets with the latest SEC information so they can work out enterprise values. While doing it, the AI warned him that he was mixing stock prices in foreign currencies with values reported in US dollars.
With about 20 credit cards, she could never keep track of what each one earns. The AI built her two dashboards. The finance one shows every card with her own nicknames for them, all her bills with due dates, one tap mark paid buttons, live checking balances through Plaid, and her credit score tracked monthly. The spending one logs purchases she texts in, like a shop name and amount on a named card, sorts them into categories, and tells her if she picked the right card, since it knows her rewards, like 6% on groceries on one card and 5% on gas on another. It also sends a Sunday morning roundup of the week's bills, reminds her which card to use before she shops, and warns her about quarterly reward caps.
