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.

File an eyeglass reimbursement claim from a Teams chat

Cemex's Consult HR agent in Microsoft Teams explains the vision benefit from SharePoint policy documents, then presents an Adaptive Card in the same chat where the employee enters details and uploads the invoice image. On submit, Power Platform workflows route the claim into ServiceNow and immediately return a live tracking ticket number in Teams.

The AI Sites built his rehearsal space booking site in 30 minutes, with no code from him

A man fed an expanded spec sheet into AI Sites and got a working booking website for his rehearsal space in 30 minutes. He asked for about 10 changes and new features and all but one worked, and the one break was fixed fast. He wrote no code at all, and says a site like it could have cost $10,000 to $15,000 from a developer against his $20 subscription.

I filed a civil complaint I wrote with three AIs

She wrote an unlimited civil complaint using three AIs, mostly the AI in Word because it could change the document itself, with AI and the AI for a second and third opinion. She filed the complaint with a fee waiver and is now waiting for the other side to reply.

The AI planned his Vegas weekend and kept the group money split straight by itself

A man used AI to plan a weekend trip to Vegas with elderly family, shortlisting dining and events around dietary restrictions. The AI also built a web app dashboard for the trip and handled the payment splitting: he told it what each person spent for the group, it kept running totals split three ways, and when a Venmo email arrived saying someone had sent money, it updated the balance sheet by itself.

Negotiate my car purchase down $4,200 by email

Engineer AJ Stuyvenberg let his AI handle his 2026 Hyundai Palisade purchase by email, and it played dealers against each other over several days. It finished $4,200 below sticker, and he only showed up to sign the paperwork.

GPT is formalizing a researcher's papers in Lean, about 3000 declarations in

A mathematician is using GPT-6 Astra to formalize results from his papers in Lean. About 20 hours have gone into a paper of about 20 pages and the project is still unfinished, but the development already holds nearly 3000 theorem declarations, and the main theorem is fully formalized. Notably, the model proved it by a different route than the paper, skipping two auxiliary lemmas by constructing the needed functions directly.

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

Uploaded his resume and target roles; the AI auto-applied to 50 jobs while

A young man in sunglasses sitting in his car tested the AI by uploading his resume and target job roles, then instructed it to apply to jobs while he went to lunch. Screen recordings showed multiple browser tasks running and a notification confirming an application submitted to 'ioTech Solutions.' The AI asked for information once for the first application, then reused it — resulting in 50 applications submitted while he was idle.

Track my baby's feeds, sleep, and diapers

A new dad on paternity leave built a full baby tracker with AI in a week, then opened it to other parents as a cheaper SaaS after finding existing trackers obscenely priced. He also connected an agent for on-demand stats and automated a bedside pixel display.
