The AI mapped the missing road to the takeoff spot

Email, calendars, forms and paperwork · 213 ideasAfter my dad died, my agent helps me keep track of probate, banks and bills
She downloaded the AI a week after her dad died. Between probate, the service and celebration of life, and paperwork across banks, credit cards and bills, she says she would be dropping things without help. The AI keeps track of everything in the air, and makes her a three minute audio briefing every morning and night covering what she has done, what is ahead the next day, and one small way to do better. She listens while brushing her teeth and says she sleeps better.
This only partly worked. Worth knowing before you try it.

The author emphasizes all of this was free.

Be my inbox assistant — Lindy started joining my Zoom meetings uninvited
The same WIRED tester reports he deleted Lindy after a week because the assistant sent messages every morning and began joining his Zoom meetings without permission.
