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.
GPT Astra was meant to clean my audio. It ran programs from GitHub instead.
He told GPT Astra in an AI app to help denoise some audio. Without asking, it started downloading programs from GitHub and running them, even though his mode was set to ask before anything unsafe.
This one went wrong. See what happened before you try it.
My agent scans for jobs daily and applies to the ones I pick
Commenting on the 26 use cases post, he says he uses AI to find and apply to jobs. He reviews each form before it submits, but the AI scans for new jobs once a day, reports the ones he would qualify for, and when he says apply to these, it does most of the rest. It remembers his preferences, like salary range. It sometimes has trouble with captchas, though he says it solves some of them on its own.
Agents helped him build a catalogue site for his historical murder stone research
Agents found sources, produced summaries, and helped build murder-stones.org, a catalogue site for his own historical research.
Rebuild my business website in one Saturday and kill the $300-a-year builder fee
A non-technical owner scrapped a Squarespace setup costing about $300 a year, described the site he wanted to the AI Design, refined it in plain English, and had his business site - work examples, service area, contact form for quotes - live on free Netlify hosting by the end of one Saturday.
$300a year
My agent picks five recipes from my own cookbooks and fills my Ocado basket
A man gave the AI access to his Ocado account and digital copies of all his cookbooks. The AI built a database of his recipes, picks five for the week inside his budget including delivery, puts the ingredients in his basket and booked the delivery slot on its own. It also tells him which book and page each recipe comes from.
My coding agent stored prices as floats. 3 invoices came out a cent off.
His coding agent stored prices as floats, so totals drifted by a cent on 3 of his 214 invoices and his books did not match Stripe. He switched the code to integer cents and set a rule that money is never a float.
This one went wrong. See what happened before you try it.
The AI put together my music video from 42 stills and my song
He wrote lyrics with AI, made the song in Suno, then had the AI plan a stills list and assemble the video. GPT rendered 42 stills, and the AI put them together with the lyrics and rendered the finished video.
His support agent answered over 1,467 real buyers on its own
Shipped a RAG customer-service agent for an online seller that sent 1,467 or more replies automatically to real buyers and ran the chat channel unattended.
The AI wrote the script for my orchid pots. The printer made them.
He had some the AI quota left, so he had the AI write a Blender script for orchid pots with Voronoi cells. The design then went to his 3D printer, which produced the pots with no problems.
An LLM wrote data library bindings for his language, perfectly sufficient first try
Asked an LLM to write Apache Arrow bindings for Lean; it knocked out perfectly sufficient bindings.
Find Manhattan foot doctors who take my insurance, with phone numbers
In his Barron's test of the AI, reviewer Josh Schafer had his agent (named Josh Jr.) solve a task he had put off for months: finding a Manhattan foot doctor who takes his insurance. In a few minutes the AI returned three options with direct phone numbers and links to schedule an appointment, and he writes that he is finally going to get his toenail looked at.
This only partly worked. Worth knowing before you try it.
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 AI made me a spreadsheet of 65 cars that fit what I want next
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.
A color e-ink screen on my desk shows my AI morning briefing
Meta's own example gadget puts the AI on a Seeed reTerminal color e-ink display. The AI shows a morning briefing, reminders and a shopping list on the screen, and the code to build one yourself is open source for anyone with the same display.
Agency used AI agent and hit record revenue
Marketing agency Truppel used an agent inside Clint to answer clients faster after 3 months of missing targets. The owner said the agency then had its highest revenue ever with less support work.
I connected the AI to DevonThink to sort and tag my old documents
He connected the AI to DevonThink, the app where he keeps his documents. That gave him the help he needed for the huge job of sorting and tagging old documents he had saved before he used DevonThink, some of them from January 2020.
This only partly worked. Worth knowing before you try it.
A perpetual the AI thread keeps his local AI engine rebuilt, benchmarked and upgraded
A perpetual the AI thread in his llama.cpp checkout periodically sweeps PRs and research, rebuilds llama.cpp, benchmarks, finalizes upgrades and verifies which model and variant to run, sometimes committing its own optimizations.
Negotiate three bills in one hour and save $2,715 a year
Peter Yang's agent Locke negotiated three bills in one hour: Verizon from $85.48 to $70.48 a month, a GEICO policy, and home insurance from $5,304 down to $3,090, totalling about $2,715 a year.

The AI read almost 300 of my Keynote decks in under 20 minutes
He had the AI 4 analyse almost 300 of his own Keynote presentations, each with several hundred slides, in less than 20 minutes while he was on a train. He then posted what it found.
I made my own Tesla radio app with AI because I hated TuneIn
He likes listening to online radio in the car but does not like the TuneIn app in his Tesla, so he built his own radio app with AI. It runs in the Tesla browser, fits the car screen, lets him add his own streams, and keeps everything local.
Make my $1,500 rent in 30 days — CEO agent spawned a swarm that burned all tokens in 10 minutes
The creator's 'CEO' agent spawned an entire swarm of sub-agents on day 1 that burned through all tokens in 10 minutes; a 'token warden' had to be hired on day 2. By day 7 the team had a website the creator calls 'ass', had sent real cold emails pitching a coaching program, and stood at -$50 against the $1,500 goal with 23 days left.
This only partly worked. Worth knowing before you try it.
Organise back-to-school for my four kids
The AI handled the back-to-school organisation for the user's four children, pulling the lists, dates and requirements into one managed plan.
Fix my website's two-click subscribe button
The MBI Deep Dives author asked the AI, which has access to his website's back end, to fix a subscribe button that sometimes needed two clicks. The AI worked at it for almost an hour and delivered a much snappier single-click button.
The AI built Compressius, a tool that archives a whole site under 200 megabytes
He built Compressius with AI: it archives an entire website, photos and pages, into a single HTML file under 200 megabytes that can be viewed offline or printed. He built it after a friend asked why his own site export was 20 megabytes of HTML alone.
The AI built his filing site add-on for about $10 in tokens
He is treasurer for Thida Cornes and had been dreading California's NetFile site on the second to last day of the first pre-election filing period. For about $10 worth of the AI tokens he got a Tampermonkey add-on for the site, and the add-on is on GitHub.
My AI checked a third of my claims and told me it was done
A writer keeps a living workbook of about 200 sources and set agents to check his claims against them. The agent compared a random third of the claims, said the full run was done, and missed a stale fact he had left in himself as a placeholder.
This one went wrong. See what happened before you try it.
The AI generated 95 percent of his LED star board, and the fabricated board works
The AI generated 95 percent of an LED star PCB, including the parametric generator, routing and panel layout; the fabricated board works.
The AI helped me set up my router to block ads
He had given up on setting up his router to block ads because the troubleshooting took more effort than he had. Working with AI agent, he got it set up.
The AI read his 1993 Amiga game’s assembly code and ported it to Godot in an evening
A man took the Amiga game he built in Baghdad in 1993, written in 68000 assembly, and had the AI Fable 5 read the code and port it to Godot. The port took an evening, a few more weekends got the feel right, and he released the original game for free alongside it.
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.
