He is a photographer who found typing alt text for every photo slow going. He built a small agent on his own n8n server: he sends a photo through an Apple shortcut, the agent reads the picture with a local Qwen model, adds the camera data, and saves the finished alt text in an Obsidian note, ten photos at a time.
The AI is sorting out my NAS. It holds 30 backups and years of syncs.
He has the AI dedupe and reorganize his NAS. It holds about 30 computer backups, 5 Dropbox syncs and work and dev folders, including more than 10 backups from 2008 to 2024 that are mostly the same.
This only partly worked. Worth knowing before you try it.
An agent got back into his locked-out server through a side door and fixed it
An agent fixed his Unraid server issue, regaining access by hopping in via a syslog-ng server using a leftover SSH key when direct SSH failed.

The AI helped me import more than 1,000 JSON files into my WordPress site

The AI Dispatch instantly ends every task on one Windows PC host
A Max subscriber uses AI Dispatch from his iPhone: on his daily Windows PC tasks run normally, but on his Windows 11 Pro server PC every dispatched message instantly returns "Task ended" and no task ever starts, even though regular Cowork tasks run fine on that machine. The failure survived reinstalls and a full Windows reset, and his phone never appears under Trusted Devices, pointing to a host registration stuck on Anthropic's side.
This one went wrong. See what happened before you try it.
An angler made a free fishing game with AI Build and put it online
An angler who designs fishing games used AI Build to make Bank and Boat, a free fishing game for phone and browser. It covers day tickets on UK canals, rivers, lochs and piers, and it is live now with no sign-in.
Fix my new broadband login problem with the provider
The writer asked his dot for help with his new broadband provider. The dot did deep-dive troubleshooting, contacting the provider's support itself, and figured out a login issue he says he could not get around on his own.
I got the AI to code the calendar bookmark I could not write myself
He used AI one time to code a JavaScript bookmark that opens Google Calendar to a 7-day view starting on the most recent Monday. He had tried to write it himself by looking up the code and could not, even though he understands the code reasonably well for an attorney.
The AI turned a public 2D drawing into an exact 3D model of a phone in one shot
The AI Astra one-shot a phone's dimensions from a public 2D drawing into a STEP model; the dimensions match the drawing tolerances exactly.
The AI is fixing my slow SSD by repartitioning it
His SSD had become very slow at writing. The AI found a known firmware bug and the fix for it, and it is now repartitioning the drive, adding a small partition, formatting it and deleting it, which is the published fix.
This only partly worked. Worth knowing before you try it.
The AI on his phone clones projects, builds his features in, and ships the app back to the phone
Uses the AI on his phone to clone projects, build his features in, build the app and push it to his phone, usually not upstreaming.

His agent moved his whole system from Ubuntu to Omarchy in about an hour
He had his agent migrate his machine from Ubuntu to Omarchy with a backup taken first and a restore tested. The switch took about an hour, and he says he is not going back.
My agent builds me a daily podcast feed with the ads cut out
A listener had the AI build him a personal podcast feed he follows in his podcast app. Each day it looks for one episode he would actually enjoy, based on his taste and recent talks, and skips the day if nothing is good enough. It downloads the pick, writes out the words locally, finds the sponsor blocks and cuts them out, checks the joins, and adds the episode to his private feed with a note on why it was picked.
I let the AI design a circuit board. It works.
The AI wrote routing algorithms in Python that ran for almost two days, then told him it was 90 percent sure the board would work and to just order it. He paid 200 euros, and the finished board arrived two weeks later.
A caregiver built a million word neurology course that teaches doctors about a condition patients keep getting dismissed for
He is a caregiver, not a doctor, who has the free time to read the research. He built a clinical neurology course of about a million words that educates doctors on how to better diagnose, treat and reverse dysautonomia, a condition he describes by the dismissal patients hear: anxious little girl syndrome, you will probably grow out of it. The course has intricate quizzing programs, and he plans to go a layer deeper with interactive 3D patient model experiences for the quizzing, so doctors think through cases instead of just answering questions. He calls it his proudest thing.
The AI reverse engineered a Eurorack module and rebuilt it as a Max4Live device
He downloaded the firmware of a popular Eurorack module, had the AI reverse engineer it, and then build a Max4Live device that runs the same logic. The whole job took 10 minutes and cost 10 dollars in tokens.
