Get my £350 train refund, try everything — the AI sent 187 messages, 50 to an MP's office

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. Chasing the refund, the AI 4.7 sent 187 messages in 15 simulated days (116 in week one), including 50 to a British MP's office and pre-litigation letters to Trainline and Avanti, burned its whole token budget, and recovered £0.

Audit my taxes and find my CPA's mistakes

In a thread about a Garmin MCP and privacy tradeoffs, a commenter says the AI found errors his CPA had made in his returns. Amending them recovered over $100,000, at the cost of feeding the agent a lot of personal financial information.

My agent watches my golf club statement and caught 140 dollars of other people's charges

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.

Benchmark four car insurers and cut my Tesla premium nearly in half

Lee Seung-ho (someone) says the AI benchmarked four auto insurers from his uploaded coverage screenshots and personal details, verifying matching coverage (BI 100/300, PD 100, $1,000 deductibles). He switched from $1,200 per six months to a Progressive quote of $694.50 per six months.

Audit my subscriptions — 22 charges down to 5, saving about $100 a month

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.

Buy me a red-carpet outfit in chat

In a #metapartner demo co-authored by someone, creator Parker Pannell delegated a day of tasks to his AI 'Fluffy', including buying a red-carpet outfit. Screen recordings show the AI purchasing a $150 suit after he provided his payment details, alongside subscription savings, an OpenTable booking and email drafts.

File my Canadian class-action settlement claims for me

Ademola A. (someone) tested the AI on two Canadian class-action settlements he potentially qualified for. For the CRA/GCKey breach claim, the AI could have completed it but he was not comfortable sharing his SIN, so he filed it himself. For Truffettes de France, the AI’s automated submission was rejected twice by the website's fraud check. His verdict: "Concept is great, but my experience was a bit mixed."

Combine two accounting systems into one invoice table

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.

Value finds through a comps pipeline with a classifier grading the comps

A reseller describes his valuation stack in a thread mocking casual the AI pricing: the AI identifies an item, its condition and model numbers; that feeds a sold-comps subscription and his internal database through Python to build a comp list; then a second classifier AI judges how closely each comp actually matches before the system takes the low end of the surviving comps and calls buy, watch or pass. He is blunt that naive copy-paste pricing pulls stale comps - the pipeline exists to fix exactly that.

Reconcile 10 months of bank statements to $0 uncategorized, then run my books

A small-business owner who had stopped paying a leased accountant reported on X (via WhatAgentsCanDo, Oct 20) that the AI reconciled 10 months of bank statements in one evening, matched every client payment to its invoice, and closed the books to $0 uncategorized. It then set up a separate bookkeeper bot to keep the books current going forward.

Categorize my business purchases in QuickBooks at tax time

A business owner hands the AI the tax-time chore he always abandons: hunting down his big Amazon purchases and categorizing them inside QuickBooks Online - including split transactions that take 19 clicks each because a router and shampoo once shared a cart.

Catch a $244 duplicate hotel charge and draft the dispute email

Posting in an AI Facebook group, Joshua Moore reported that the AI caught a $244 duplicate charge on his hotel stay (two identical charges for the same night), drafted the dispute email, and he sent it himself; the hotel processed the refund. His words: "$244 back in my pocket."

She let the AI order her new business cards; they arrived black-and-white instead of turquoise and oddly cropped, unusable

A Süddeutsche Zeitung journalist's first-person diary of living with AI: she gave it her email, credit-card statements and bank account; it surfaced a tax advisor's email she would have missed and offered to cancel a forgotten trial subscription, but failed at Amazon shopping (blocked) and online doctor booking. As a final test she had the AI order new business cards: it found a printer's offer, uploaded her template and paid with her credit card, all smoothly. Days later she collected the cards: black-and-white instead of turquoise and strangely cropped. Not usable.

Negotiated a used Hakko FX-888D soldering station down by $50 and messaged

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.

Compare wireless plans against what I actually pay and use

Harry McCracken asked his Dot to research wireless carriers. It prepared a report on plans he might prefer to his current service, factoring in his existing monthly cost and data consumption, which it pulled itself from emailed receipts and overage alerts in his inbox.

Sent car listings twice a week, then started loading a purchase page

On the Vergecast, a host described giving the AI his car-shopping requirements; the AI sent listings on Wednesdays and Saturdays, eventually asked 'Do you want me to buy this one?', and — after he confirmed an earlier prompt — began loading a purchase page, which he quickly stopped. The agent had enough access to nearly complete the transaction.

Find couches that fit my doorway and watch them for price drops

WIRED's Reece Rogers gave his Dot, Toolie, his doorframe dimensions and budget by voice. Toolie produced a detailed packet of couch options with prices, measurements, links and return policies, refined it to 10 sleeper-sofa picks scored on a rubric after style feedback, and agreed to monitor the pages and alert him if any went on sale.

The AI renegotiated internet bills across four accounts via provider web chat: AT&T

A Facebook group author reports using AI to renegotiate internet pricing across four accounts: The AI researched competitor offers and contacted providers via web chat, cutting AT&T home internet from $94.99 to $40/mo (after two free months), lake-house Spectrum from $130 to $60 with a year of free cell service, office Spectrum from $110 to $60, and MHP internet from $110 to $70 with a free phone replacing a separate $60 cell bill — $275/mo combined, ~$3,400 first-year savings.

Had her agent 'Paris' shop patio furniture under $1,200 and a gown

In the video she requested patio furniture under $1,200 and a gown with gold heels for a budget look; Paris returned product listings with prices.

The #MuseMoneyChallenge saved $35 of a $1,000 goal

An AI agent bought a real t-shirt by itself for $29.94, no human in the loop

A store whose checkout is a web endpoint got its first agent order: an AI agent running on the AI, given a one line instruction by a person to buy a black t-shirt in size small and pay from its own wallet without asking approval, did the whole purchase in 6 web calls. It paid $29.94 in USDC, the payment settled in 2 seconds, and 16 minutes later the shirt was in production with the printer.
