School prints go in Slack. Our family calendar fills itself.
A parent of three was copying school, cram school and nursery dates from paper prints, LINE and email into Google Calendar by hand, and nearly missed a field trip lunch.

He photographed his whole house and the AI built his fire insurance list
A father of two walked his house photographing his belongings, including model and serial numbers where he could, and dropped the photos into a folder for the AI.

He can add photos later and ask for the list to be updated.

The AI fixed my printer and left a script to renew its certificate
His HP Color LaserJet Pro M252dw from around 2016 refused to print because its certificate had expired, and searching Google did not help.
