Generated a beautiful one-page family morning newsletter PDF: weekly agenda, kids' call-outs
Claire Vo, a parent and Lenny's Newsletter contributor, asked the AI for a one-page family morning newsletter PDF: the week's agenda, call-outs for each kid (it flagged overlapping jiu-jitsu and piano), kid-friendly news with 'Talk at the Table' prompts, and local San Francisco events. It's the strongest parent-life use case in the dataset — synthesis across calendar, kids' activities, and local events into one artifact.

The AI called Cigna about a six-month-old travel medical insurance claim, introduced itself
The author describes using AI to resolve a six-month-old travel medical insurance claim with Cigna.
