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.
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.
The AI migrated a password reset flow at work, and it was slower than doing it by hand
The AI migrated a password-reset flow in a real work codebase over half a day, producing decent code but slower than doing it by hand after babysitting and cleanup.
This only partly worked. Worth knowing before you try it.
My noon job scan checks every link is live before it sends me the list
His scheduled the AI scan runs at noon daily over about 15 job sites plus any others it finds, matching UK product owner and knowledge management roles at £45,000 to £65,000 against his uploaded CVs. It drops anything posted more than 48 hours ago, anything hybrid sold as remote, and anything it has sent before, and it checks each link is still live, ideally on the company's own site.
The AI drafts the reply to my weekly ad report on its own
An outside agency runs some of his advertising and sends a report with the numbers every week. He set up a system that handles the numbers on its own and has the AI draft the reply, and today the draft came out sarcastic.
The AI published my Bluesky post from my phone through my PC
He set up a chain from his phone to the AI to his Windows PC and a background browser. The PC published a post to Bluesky and checked it had gone up, while his other screen work kept running separately.
Non-engineer lets the AI run his note publishing operation overnight
On Oct 2, 2026 a Japanese non-engineer asked the AI to run his note account for monetization; the agent picked the niche itself, then researched, drafted and self-reviewed 12 manuscripts during his 5-hour nap, reaching 42 drafts by the end of the day. It now plans topics, writes drafts, creates header images, registers the posting schedule in Google Calendar and prepares X and Threads announcements, batched a week ahead for his approval. The AI’s own safety feature stopped it from pressing the X post button; he keeps five jobs human: purpose, identity details, the final post button, personal experience and publish approval.
The AI could not get past the robot check on delta.com
A Delta flyer asked the AI to check that he was using all his Delta benefits. The AI could not get past the robot check screen on delta.com, even when he took over the browser and clicked it himself. Every login try was blocked.
This one went wrong. See what happened before you try it.
The AI’s animated demo explained the night sky to his 5-year-old better than anything he found
The AI whipped up an animated demo to teach his 5 year old why the sky is not black, a better explanation than existing ones he found.
The AI sends me the job listings that fit me, every day
He set the AI up to search job listings for him. Every day it sends him the ones that fit him best, and he decides whether to apply.
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.
