Level up how you use AI

Real things everyday people got it to do, and how to try them yourself.

Shuffle again

A random mix from the whole library. Shuffle for a new set.

WorkPartly worked

Build my landing page — but I could not preview it

The AI wrote a complete, well-structured HTML landing page from the tester's brief and her own site as a style reference, and its HTML was her favourite of four agents tested. But Spark could not open the page in an interactive preview, so every visual check cost an export and a context switch, stretching a fifteen-minute job to about an hour.

This only partly worked. Worth knowing before you try it.

The AI wrote the system docs I owed before I could retire

He let the AI go through his system and write a first pass of the documentation, including the billing part he felt he had to finish before retiring. The remittances section alone used up a full day of tokens, so the work ran over several days, but it got done and let him retire, or at least half retire, a little earlier.

FoodWent wrong

Build my clean-eating Instacart basket — it shopped for a family of 12

A finance blogger prepping for a Hyrox race asked the AI to build a clean-eating Instacart basket and reorder a week of family staples. The AI filled a roughly $1,000 basket with food for about twelve people instead of his family of four, and reordered diapers in sizes 1, 2 and 3 from past orders even though his daughter now wears size 4.

This one went wrong. See what happened before you try it.

Haus Hunter: run my home search like an investigator

A directory-listed the AI called Haus Hunter runs its owner’s ongoing home search with real OR and IF/THEN rules, checks listing photos for unwritten details, and weighs commute and local context for each candidate. It investigates homes the way a good buyer’s agent would, continuously.

Agent workflows I built make our invoices and send our emails

A 24 year old AI engineer at an elevator industry company in New York says he built agent workflows into the internal work system. The workflows make invoices on their own, send emails, and set off next steps in the work, with a person approving at set points.

Match 904 insurance documents overnight at my dental clinic

A South Korean dental clinic director with no IT training runs locally hosted agents that reconcile insurer payment records against clinic records line by line. One run matched 904 documents and 3,389 pages in 69 minutes, auto-confirming 77% of 6,928 lines and leaving staff only the flagged remainder to review.

A highways engineer built a routing tool that scores roads by five years of crash data

He works with collision data as a UK highways engineer but could never answer the simple version for his own commute: which route has actually hurt people. He built SafeRoute with AI, which plans a route and scores it on five years of collision records; colleagues then asked for the same data as branded evidence reports for committees, which the tool now produces in about 30 seconds instead of a day of manual work.

Sunday lesson planning went from up to six hours to fifteen minutes

He teaches part time at a private school. Lesson plans go in six weeks ahead, and every student now gets a personal differentiation plan, which used to be done per group because per student was not feasible. The Sunday session that took four to six hours now takes fifteen minutes, plus short daily reviews of content and parent comments.

Life adminWent wrong

Move my client meeting and follow up — failed on a wrong email assumption

Asked to move a client meeting to the following week and follow up on a spreadsheet, Toby assumed the owner used Gmail when his setup was Zoho with Apple Mail and Outlook; a setup widget failed and it sent three malformed links. Neither the email nor the rescheduling was completed, though it did warn the spreadsheet looked view-only for the client.

This one went wrong. See what happened before you try it.

Turn my stalled personal goal into a daily action checklist

A personal blogger gave the AI one of four life goals that wasn't progressing and it evolved into a daily morning action list of readings, videos, questions and assignments. She then had it converted into a checkable checklist so she can track progress and stay accountable day to day.

Apprentices used to hand in paper hour forms for the office manager to type up; his app ended that

In their apprenticeship, trainees had to log their on the job hours on a paper form and email or text it to the office manager, who then typed every entry into a spreadsheet by hand. He built an app so apprentices can submit their hours directly. Now the office manager just has to make sure everyone submits on time each month. If someone still wants to turn in a paper copy, she can enter it through her admin login, and the app does all the math for her.

Move my rental-car pickup to Charlotte after my flight falls apart

Jared Lee was flying to New Bern, North Carolina, where his father may be dying, when delays at lunch told him he would miss his connection. His rental car was booked for New Bern airport. From the taco restaurant, he asked the AI to change the rental to a Charlotte pickup for the 4.5-hour drive. A couple of text messages later it was done: new rental, new confirmation. He estimates it saved him at least an hour of hold time, spent instead present with his wife.

The AI rebuilt our network proxy tool in 6 weeks. Doing it by hand had taken 16 months.

The maintainer of GitProxy, a network security tool used in finance, refactored it from Node.js to Java with AI working as a pair. Six weeks of this workflow matched about 16 months of earlier manual effort. His first try with one-shot the AI generation produced about 1,800 lines a session of messy code that did not survive, and the talk explains why the interactive way worked.

Fill three dead hours in Manhattan with a route matched to my mood

Stuck in Manhattan with three hours to fill after a drop-off, Eric planned the afternoon with Jarvis by voice while driving. He gave it a mood instead of a destination — a break from technology, maybe by looking at art about technology — and it weighed a museum, galleries and an observation deck, then came back with a walking route through Chelsea galleries. At the end of the call he told it to put the route in his calendar, and it did.
