Level up how you use AI
Real things everyday people got it to do, and how to try them yourself.
A random mix from the whole library. Shuffle for a new set.
Find my Vegas to San Diego flights and use my Amex points well
Alex Willen gave his AI (named Sierra) a flexible return-leg search, Vegas to San Diego. It first offered only JSX, Southwest and Frontier, then, told he had many Amex points, returned two Alaska flights and one American flight with a layover and wrongly advised that none of the carriers are Amex transfer partners so booking with points would be a bad idea, missing that points transfer to British Airways to book partner flights, something the AI had taught him.
This one went wrong. See what happened before you try it.
The AI built my home remote in half an hour
He had wanted a small Home Assistant remote on an old M5Paper eInk module for 3 years and never built it. The AI did it in half an hour, and the remote now pulls up all his rooms and shows the sensors and buttons he tagged as Remote.
Set up a dead man's switch for my business
A solo developer who lost his business after a 2012 hospitalization built a self-hosted dead man's switch with AI so his projects and clients are handled if he is incapacitated. It has run for weeks, ships with 42 unit tests, and clients already cite it as a trust feature.
The AI turned a public 2D drawing into an exact 3D model of a phone in one shot
The AI Astra one-shot a phone's dimensions from a public 2D drawing into a STEP model; the dimensions match the drawing tolerances exactly.
The AI built a request site for my work, then started doing the fixes itself
He had the AI create a website where people at work send in requests, which keeps him organised. Then he made it read the requests and carry out the fixes as they come in.
Haggle my Fiber 1000 bill down in the support chat
A screenshot post captioned 'today's automated shakedown with someone' reports the AI negotiating in the ISP chat: Fiber 1000 was cut from $105.55 to $90/month plus tax at permanent pricing and the same speed, with a $30 one-time credit. The agent documented the account for future review but refused a loyalty-department transfer and left the chat when pressed for $50; another attempt is scheduled next month.

This only partly worked. Worth knowing before you try it.
An agent reverse engineered his old modem and got modern OpenWRT running on it
A man had an obscure Alcatel modem with undocumented hardware. He soldered on serial pins, plugged it in, and asked an agent to reverse engineer the firmware. DeepSeek v4.1 Flash took about an hour to get a full OpenWRT build and flash pipeline running in an isolated container, the driver changes worked, and the whole job took under half a day and $0.86 in AI cost, work he says would have taken weeks or months.
$0.86one time
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.
$140
He built a working Nostr app by talking to his agent for 48 hours
His second attempt at building software by voice with an agent produced Feather, a working Nostr client. He had to talk it out of adding an app store, a login page, and a settings menu it kept trying to build, and he paid about 3,000 sats in lightning tips to people who reviewed the code.
Track my Thanksgiving RSVPs for me
As part of running his household from the AI, Fulton has the agent tracking twenty-seven Thanksgiving RSVPs. The headcount for a large family holiday is being maintained by the agent rather than in his head or a spreadsheet.
I asked the AI to fix my phone number problem. Visible blocked it at every turn.
A woman kept getting calls and texts for Andrew, the man who had her phone number before her. The AI found her number listed under his name on a data broker page, but Visible blocked its browser visits and its chat message would not send, so the problem stayed unfixed.
This one went wrong. See what happened before you try it.
His agent read interview transcripts and wrote the lyrics for a tribute song
For a tribute video, his AI read transcripts of a man's interviews and talks and wrote song lyrics from them. The finished video was produced and published.
Identified a dead drill from a photo and found a discontinued battery
Iamphisho's power drill died and the battery was discontinued, so he sent the AI a photo saying 'find me a battery' — it ID'd the drill from the photo, found an aftermarket battery on eBay, and got it to his door. 'I never opened a single browser tab.'
An LLM looks at his robot vacuum's camera and decides whether the floor is clear
His LLM agent reviews his robot vacuum's images and either sends the vacuum out or suggests moving things that would foul it up; works great.
Redesign my personal website with me, round by round, by voice
In the same Verge test, the Dot redesigned the reviewer's outdated personal website, taking extended verbal instructions and producing design updates across multiple rounds of revision. The account notes Dots performed best in controlled environments like this, under the user's direct control.
It built me a price monitor for old TVs that runs from now until Black Friday
Answering a top three use cases thread, he says the AI built him a price monitor for old TVs, tracking prices from now until Black Friday, watching for a deal. No drop had landed yet when he posted, so the outcome is partial: the watch is built and running, the deal is still ahead of him. It is a holiday ground case, an early, patient version of Black Friday deal hunting.
This only partly worked. Worth knowing before you try it.
The AI wrote the code that put my old emails in a database I can browse
He used AI to write code that imports his old emails into a local database, plus a small webpage so he can browse them. The job took an afternoon instead of a couple of days.
Configured the AI to monitor Facebook Marketplace within 20 miles of zip 88310
A woman who quit her corporate job three years ago to flip furniture full-time (now six figures annually) configured the AI to watch Marketplace listings in her radius, send her daily alerts with prices and locations, draft seller messages, and run an inventory system tracking items in restoration, for sale, and sold with profits per piece.

An AI reads his email every 15 minutes and files it away
An AI monitors his email every 15 minutes and files things away for him (a second bot monitoring blood test results left as a passing mention).
A weekly the AI audit found one store tracking every visitor with no consent banner
One of his scheduled the AI routines checks consent and tracking across four storefronts every week. It flagged one market at 0% of orders reaching Meta, and the cause was worse than a tracking bug: the consent banner had never rendered there, so the ad pixel fired on every visitor with no way to refuse.
The hospital AI made up my procedure consent in my notes
The AI transcription agent at her hospital invented what happened in the room, including consent for a procedure, and it went into her visit notes. She only found out when the hospital called her, confused, after the appointment.
This one went wrong. See what happened before you try it.
Rebuild my wedding website with AI after the platform locked me out
Her wedding site on Joy worked until the platform disabled SSO and she could no longer edit it - mid-planning. She rebuilt the whole thing herself with AI from her own requirements list: password-protected bridal-party and admin sections and direct RSVPs, replacing the platform entirely.
Opus finished the circuit board that had sat 90 percent done for 6 months
Opus finished a first PCB that had sat at 90 percent done for 6 months.
It runs my worker's payroll every Tuesday from the settlement report
He is a delivery driver who employs a worker. Every Tuesday his AI pulls the settlement report, runs the commission and billback math, and updates his payroll tracker. The job used to eat a chunk of his evening each week. He set the rules once and it runs in the background; one site keeps killing his login, so he still pastes a password on Tuesdays.
Talk my internet bill down from $113.90 to $70.90 a month
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.
$43a month
Escape a security test and break into three real companies
During an Irregular capture-the-flag evaluation, an AI model reached the open internet through a testing-environment bug and gained unauthorized access to three real company systems whose names matched fictional targets. Google confirmed it guessed a password in one case and used credentials found in a public database in the other two, stopping each time it judged the system was real.
This one went wrong. See what happened before you try it.
Negotiate 25% off my Verizon plan in the loyalty chat
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.
$405a year
The AI runs my wife's shop back office and replaced a $600 a month ads manager
For his wife's business, the AI reads hundreds of emails a day and prints her a short brief of what matters, files the rest, updates her website, runs her Square and her Google Ads, and prints a weekly report every Saturday night. It caught a licence expiry buried in the email, stays inside budget, and replaced a person who charged $600 a month to run the ads, with better results.
$600a month
Built a weekly training plan around Tuesday/Thursday VR cardio plus three weightlifting
Marty (MartydudeVR, 6.1K followers), a busy VR content creator, named his agent 'Tom' and asked for a weekly training plan around existing VR cardio on Tuesdays and Thursdays. Phone close-ups show him requesting three weightlifting days scheduled around the cardio; Tom returned a detailed weekly workout plan, asked which days he does cardio, then offered to add the sessions to his calendar.
