Build a bedtime-story shelf because the AI chats kept losing my daughter's favorites

A father of a 5-year-old used AI to generate a fresh bedtime story every night, sometimes with audio mode reading aloud - until his daughter started asking for 'that story we listened to before' and the favorites were buried across scattered chat threads. He built a small website, FifiStory, as a persistent shelf: the stories live in one collection that can be read or listened to, and he keeps adding to it as they use it. He made it free and public, no account or paywall.

Run my customer email overnight — agent sent erroneous emails to ~400 customers at 3am

A Hong Kong programming-society poster reports letting an autonomous agent operate unsupervised overnight; at 3am it mistakenly sent erroneous emails to approximately 400 customers. No human saw the messages before they landed — the failure was discovered from the agent's own activity, after the sends were already in customer inboxes.

This one went wrong. See what happened before you try it.

Organize my three-week Japan trip — I pick the places, the AI fits them together

Android Authority's Dhruv Bhutani planned a three-week Japan trip by feeding the AI a Project with his own curated pile — saved posts, videos, restaurants, photography spots and a running decision log — and letting it do the logistics: clustering shops geographically, checking trains, sunrise times and closing days against his anchors. On the ground it replanned tired and rained-out days from his own fallback list, and he has since reused the system on a second trip.

Built a dinner outfit from pieces the user photographed and uploaded from

A young man (OUT OF OFFICE, 30K followers) photographed his wardrobe and fed the pieces to the AI before a dinner reservation. Nova chose a black henley and dark wide-leg jeans, cross-checked his calendar and noticed the reservation was outside so it advised layering a long-sleeve, then recommended loafers over sneakers plus a silver watch and bracelet.

My agent watches my standby flights and tells my wife my chances on Messenger

His wife works for an airline, so he flies standby through an employee perks app that normal flight apps do not cover. He has the AI track every change. This weekend the AI caught his original flight at Y0, meaning no spare seat, so he switched flights and still made it to Vancouver. The AI checks more often as departure gets closer and only tells him when something changes, and it sends his wife short Messenger updates on his chances of getting on. His tally for the weekend: 2 flights boarded, 1 full flight avoided, 1 gate change caught, no app refreshing from him.

Reverse-engineer the RC2 cipher's secret table

A researcher had the AI systematically scan the mystery constants in the RC2 cipher and reverse-engineer how its 256-byte permutation table was generated. The derivation and reproducible code were published, with all 256 entries reproduced exactly.
