Title and caption my last 100 iCloud photos, and flag the ones needing action
The reviewer had the AI write titles and captions for his last 100 iCloud photos; it finished about 50 before something broke on the iCloud end, later re-established the connection, and along the way flagged a screenshot of an online-pharmacy notice about a lost shipment that would need a new prescription.
This only partly worked. Worth knowing before you try it.
Phone recordings land in my notes, transcribed by the AI

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.
Audit my own AI usage and show me where I waste tokens

The cron job reported ok — its message was never delivered (failure)
An AI cron job's Telegram delivery failed on a transient network error, but the stored run record still said status ok with delivered false, consecutiveErrors stayed at 0, and nothing retried or alerted — the scheduled message simply vanished. The failure was only visible by digging into the run diagnostics; anyone watching the chat or the job's status saw a healthy run.
This one went wrong. See what happened before you try it.
Build me a chess dashboard with a snarky coach
In the same interview, Alex Cornell mentions the AI built him a chess dashboard that analyzes his games with a snarky coach persona (segment from 29:39). It sits alongside his golf tracking as one of the personal dashboards he actually lives with.
