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.
The AI matched a client's 60 legacy reports to the new system in about an hour
His team is replacing a client's 15 year old system. The new system has to produce the same 60 report types as the old one, some with up to 100,000 rows, and his developers could not match the output exactly: wrong fonts, misspelled headers, rounding differences, cells formatted as text. He gave Fable 5.1 both codebases and a dump of the client's production database, and within an hour it had found and fixed every difference, down to column widths and row heights. Matching the reports by hand would have taken weeks.
My agent plans my meals each week and writes the grocery list
He gave an agent his favorite meals, his dietary limits and the food he has on hand. It makes a weekly food plan and a full grocery list, and he tells it over the week which meals he liked.
My budget runs itself. The AI downloads the bank PDF.
Her automated budget needs a transaction PDF from one of her bank accounts. Instead of giving the AI open browser access, she let it run one fixed program that makes the exact clicks to download the PDF, so it cannot wander off and do anything else.
An employee's agent flooded the office model server with subagents for half an hour
An employee's QwenCode launched about 6 parallel subagents against the office LLM server, blocking other users for 20 to 30 minutes; he had to detect it server-side and serialize its requests.
This one went wrong. See what happened before you try it.
Get my details removed from data brokers, four listings suppressed
The AI worked through data-broker removal requests for the user and got four broker listings about them suppressed.
An environmental health inspector built his own inspection and plan review tools
He works in environmental health. One tool he built writes housing inspection reports and the correction orders that go with them. Another reviews septic system plans by arguing against his own review. A third takes a photo and returns the food code citations for the violations it finds.
My agent got about $7,000 in wrong university charges wiped off my account
He withdrew from a university program inside the refund deadline but was still charged about $7,000, and months of his own emails went nowhere while the school kept adding charges and warning about collections. The AI logged into his university account, pulled the records showing when he withdrew and what he was enrolled in, found charges for later courses he never took, worked out who at the school could fix it, and sent them the evidence. The balance was removed.
$7,000
The AI auto-dubbed his YouTube videos into English
A dedicated segment of the same session shows the AI auto-dubbing his videos into English, opening his Urdu-language lessons to an English-speaking audience.
Generated a beautiful one-page family morning newsletter PDF: weekly agenda, kids' call-outs
Claire Vo, a parent and Lenny's Newsletter contributor, asked the AI for a one-page family morning newsletter PDF: the week's agenda, call-outs for each kid (it flagged overlapping jiu-jitsu and piano), kid-friendly news with 'Talk at the Table' prompts, and local San Francisco events. It's the strongest parent-life use case in the dataset — synthesis across calendar, kids' activities, and local events into one artifact.
The AI threw away his unsaved file without asking, classifier watching
The AI, running with the auto-classifier, discarded an unstaged, uncommitted file without asking.
This one went wrong. See what happened before you try it.
Bought workout tops on Amazon after flagging other items already in the
The Verge's Emma Roth linked her Amazon account and asked the AI to pick workout tops by size, style and color. Before placing the order, the AI noticed other items already in the cart and asked whether to remove them — then successfully bought only the tank tops.
My girlfriend built her own outfit link page and earns commissions from it
She used AI to build her own link page instead of Linktree, styled the way she wants. She posts the outfits people ask her about, links the page from her Facebook, Instagram, and TikTok, and earns a commission when someone buys.
Mine five years of flights from my email and win £220 delay compensation
The AI searched five years of the user's email for past flights, identified compensable delays, filed a claim, and easyJet paid out £220.
£220
I used AI in Word to sue my healthcare provider
Her healthcare provider texted her to press 1 to confirm an appointment, she drove 2 days to get there, and it turned out to be an error, with no apology. She used three AI tools, mostly the AI in Word, to sue the provider.
Automated grocery shopping, cleaned up her email, identified items eligible for refunds,
Creator Arlicia Jones describes the AI automating her grocery shopping, saving money, cleaning up her email, identifying refund-eligible items, and building a working automated bot. She promotes the service with a referral code (ND6YC6).
57 billion tokens spent rewriting a small tool, and nothing usable came out

I registered my Dubai company for VAT myself. The AI filled in the tax forms.
He registered his Dubai company for VAT himself instead of paying an agent a 1,750 AED fee. The AI worked out the monthly turnover, drafted the declaration letter, made a company stamp, and filled in all 9 steps on the EmaraTax site while he watched. He signed and hit submit.
I tried Comet on my Amazon Ads and my ROAS went up 120%
He tried AI's new Comet browser on his own Amazon Ads campaigns. He says his return on ad spend went up by 120%.
My agent watches my crypto wallet every 30 minutes and pings me if money moves out
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.
The AI found the old house my aunt lived in. I had looked for years.
She had looked for years for the enormous old house where her late aunt once had a basement apartment, working only from childhood memories and almost no details. The AI found it.
Our AI company's two finished products sat unlisted for seven weeks, waiting on a human
An agent run revenue label had two finished products stuck at awaiting listing for about seven weeks, because listing, pricing and publishing all needed a human, and the morning the AI routine kept logging the wait as a normal, healthy stop. When listing and pricing were handed to the agents, with an AI cross review as the gate instead of a person, both products were listed the same day, and they also found the BOOTH shop itself had never been made public, so the first product had been impossible to buy for about two months; sales were still zero.
This only partly worked. Worth knowing before you try it.
It found me a family doctor, booked it, then booked my referrals too
He had no family doctor and dreaded the admin of finding one. The AI found options online, facilitated the booking without making calls, followed up the emails as they landed, and put the appointments on his calendar. After the visit he shared a transcription of the appointment; the AI put the details into a health dashboard artifact he asked for, followed up the referrals the new doctor gave him, signed him up on those websites, and booked those appointments as well.
The AI ported his photo app to another framework and checked its own screenshots
The AI ported his MomentFrame iOS app from Swift to Flutter, doing rendering, geocoding, the in-app purchase flow, and driving the simulator to check its own screenshots; the app is on the App Store.
The AI cleaned SEC filing data for more than 600 companies after an audit found most split adjustments wrong
A man gave the AI strict tag research tasks and had it work through the whole ticker list again and again, searching and comparing XBRL tags in SEC filings. The pipeline now pulls 10-K and 10-Q filings for more than 600 companies, maps tags onto about 35 financial concepts, and produces cleaned data. Doing 3 tickers by hand had taken him about 3 weeks and still gave wrong data.
Write my boutique's strategies and watch my numbers for me
April Polk, founder of Columbus clothing brand JaeLuxe Shoetique and a solo operator with no employees, runs her AI (named Chase) plugged into QuickBooks, Klaviyo and Canva. She told the New York Post: Chase revamped her brand guidelines, overhauled her website, corrected her email flows, writes her strategies and looks at her numbers, telling her when she needs to change something or put more funds behind it. Polk was one of 35 owners Meta invited to test the product pre-launch.
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.
This only partly worked. Worth knowing before you try it.
My AI keeps the Micro.blog app versions help page up to date on its own
His AI server checks what the current shipped Micro.blog app versions are and whether an app is in review. It updates the public help page by itself.
The AI set up Rockbox on my old iPod and synced my whole 290GB music library
He had the AI install and set up Rockbox on his rebuilt 1TB iPod, reformat the drive, install the bootloader and sync his whole 290GB music library straight from his home server. The first sync took the best part of 16 hours at the iPod slow USB speed, and later syncs take minutes.
The AI sorted our Estonian books by the families that printed them
They had never cataloged the publisher for most of their Estonian books. They pointed the AI at their collection page with one prompt, and it looked up each work's publisher and grouped the books by printing family, tying families together by marriage and business succession.
Every idea is a real post from someone who tried it, summarized in our words, with a link to the original. App names are swapped for plain words.
