A random mix from the whole library. Shuffle for a new set.
Dan Zhao posted a dark-mode screenshot recommending the AI for auto-insurance shopping, claiming over $1,000/year in savings. The comparison shows six-month premiums: Progressive $1,556 as the new leader vs Costco Connect $2,142.75 and current GEICO $2,324.63.
An ‘Invoice Terminator’ the AI desk closes its owner’s month every month, pinging him only for 2FA and a final yes; on one run it caught a $64 Cursor invoice that would otherwise have escaped unpaid and unnoticed. The monthly close runs itself, with the human as a checkpoint, not a worker.
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.
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.
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.
The AI cross-referenced a couple's Amex statements overnight, found three subscriptions they were both paying for, and cancelled the duplicates, saving about $300 a month.
A man needed hardware for a piece of furniture and ran AI to find it. It beat his best Google results by 18% by finding smaller shops, applying a discount code, signing up to a newsletter for a better code once he approved, and checking the shipping by putting the item in the cart and going to checkout.
He gave the AI an xpub for his crypto wallet. That is watch only access: The AI can see the public addresses but cannot move anything. The AI checks the blockchain every 30 minutes and pings him about any outgoing payment, so if his seed phrase were ever stolen he would know fast.
Built a purchase history scraper for Amazon and Kroger with price and quantity history views.
Elon Musk posted that he asked the AI to research the most fun Lego Star Wars kits for young kids and order them; the shared confirmation showed five sets totalling $241.34 with free delivery. The screenshot also exposed his order number, email and partial card details, and users claimed they used them to try to cancel or alter the order via Lego’s service bot.
Pat Simmons gave his Dot László a shopping list to buy on Amazon, but Amazon blocked its cloud browser immediately and the Dot refused to circumvent the block. Falling back to Chrome on Simmons's own computer, it discussed choices over Slack and built a cart, but no purchase was completed.
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.
Shriya Nevatia had the AI build a personal fashion app from her measurements, photos, favourite stores and budget ranges. The app picks a hero item, builds outfits around it, and keeps a saved list.
He built BinkBook, his own app that turns photos of poker tournament receipts into a dashboard, and says the AI now does the job better. He snaps a photo and the bot saves it to Google Drive, pulls out the casino, date, game type and buy-in, and logs it in a Google Sheet.
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.
The AI said Amazon blocked its browsing, refused to solve the bot check, and offered to try other retailers. Amazon shopping was 'off the table' in her tests.
A screen recording shows a user asking the AI to review three months of bank statements across three connected accounts and say where the money goes. The AI reported $4,320/month average spending against $4,850 income, dining up 35% to $410/month, and three subscriptions totalling $47/month unused for 90 days, offering to cancel them.
The same writer set the AI a daily price watch on a WWE Blu-ray. The AI checked listings each day and pointed him to a copy on eBay under $20 with free shipping, bundled with another disc he plans to sell on.
His invoice agent processed 688 documents in 30 days at about $0.11 per document and made 3 errors, with no retry storms. He is open that a document marked completed does not prove every field was read right, so the numbers count finished documents, not verified ones.
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.
