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.
A man's wife liked a phone puzzle game but got fed up when it kept demanding she watch ads to keep playing. The AI rebuilt the game as one web page with a daily challenge, all time stats and as many puzzles as she wants, with no ads and a cat theme, for about $25 in token costs.
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.
A man built a small rig for his single board computer with two microcontrollers, one for the serial terminal and one running a servo taped to power switches so the AI could power cycle the board itself. Left running, the AI spent all day and night working through the board’s network chip quirks until the driver worked.
Feifei Qiu reports handing the AI her subscription and bill stack. The agent found an unused Verizon perk to shift one plan onto and cancelled three auto-renewing subscriptions, reporting about $720 in savings within an hour.
Three days into AI Duet, the time saved came from it acting first. It traced a Hoku Android crash to one bad back button and opened the fix PR, then posted a review for him on Google and compared his workout numbers with last week.
After reading the AI’s summary of an embargoed PR pitch, Ulanoff had it draft a reply. The first draft overpromised a meeting, so he had it strip the meeting references to just agreeing to the embargo and getting images and details.
Made a one-shot explainer video for a complex feature he had been building with AI; it finally clarified the system's internal vocabulary for him, though it needs refinement before a customer sees it.
He added a feature to his blog that uses GPT-6 Luna to look at each daily comic and add a note about what is in it. Doing all 270 comics cost about 20 cents in total.
Josh Pigford started FirstIndex, a service that gets companies found on Google and in an AI app answers, at $1,000 a month. Within a month it was at about $570,000 a year in recurring revenue with about 30 clients, and the AI does most of the delivery work.
The AI reads the reviewer's Strava trend data, which is normally shown as charts a screen reader cannot use, summarizes it in words, and correlates it with his data from the Apple Health app.
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.
