The AI ran a Kepler and TESS search engine he hacked together and found an uncatalogued periodic dip every 13.77 days around KIC 5689121, a possible 2.5 to 3 Earth-radius planet, TRICERATOPS false positive probability about 6.9 percent (result report, not a product pitch).
This only partly worked. Worth knowing before you try it.
I built an app to move my notes between my Boox and my Samsung
He takes notes on both a Boox and a Samsung device and the two formats did not mix. He built an Android app with AI that converts both formats back and forth, so he can move his notes between them.
My AI reads my email so I do not have to
He does not read his emails anymore. His AI, Mrs. Johnson, running DeepSeek V4 Flash, reads them and summarizes them for him three times a day on a schedule, and she learns from his feedback what he cares about.
Her agent 'Jarvis' runs her day (gym, meals, proposals) and built a
Lennster named his agent 'Jarvis' to stay organized through a life overhaul: it checks his daily calendar (walking, content, gym, lunch, proposals, dinner, work), found protein-meal restaurants in Jimbaran (Healthy Tribes, Menega Cafe, Fit Bowl Bali), and built a 'Specimen Split Tracker' logging weights, reps, and PRs (Zercher squat, Bulgarian split squat, neck curls).
He designs his own furniture with AI and gets cutting blueprints in a couple of hours
A hobbyist designs his own furniture in OpenSCAD with AI, reusing code from earlier pieces. A new design takes a couple of hours including the PDF blueprints, drawn like shop instructions, that he prints so the person cutting his wood panels cannot go wrong.
Turned an anonymized GEDCOM of ~3,000 people into a 300-frame animated pedigree
A genealogist handed his AI an anonymized GEDCOM with about 3,000 individuals. The AI wrote a Python program drawing 300 frames into a 10-second MP4 animated pedigree (ancestors fade in by birth order, glow while alive, dim at death, living shown as 'Living'), then produced an 11x17 300-DPI print from a single frame.
The AI found a never saved Pages document in the iCloud cache
A Mac user deleted a Pages document by mistake before ever saving it, so it was not in the Trash or Time Machine. The AI searched the whole disk, including iCloud cache files, and located a copy in the CloudKit cache folder, and the document was recovered.
The AI turned an archived adventure game into a web version, then a 3D one
He pointed the AI at an Internet Archive copy of an old adventure game and got a web version of Neuromancer, then a 3D version.
Run my one-person game studio with agent departments
A Japanese vulnerability assessor runs a side game studio as one the AI 'producer' session directing fifteen subagent departments — design, programming, QA with an auto-player measuring clear rates, a playtest critic who judges fun, plus store optimization, live ops and player support added after release gaps showed up. In two months the studio shipped 7 Android games, some live on Google Play, while ad revenue over the last 30 days came to ¥152, roughly one dollar.
