It hit me while I was standing in the grocery store with my phone out. I don’t use note-taking apps anymore. My shopping list was sitting in a persistent chat with ChatGPT, right where it had created it for me after helping me plan my family’s meals for the week. It even specified my daughter’s favorite yogurt.This wasn’t a one-off. I had slowly started using ChatGPT as a productivity tool for every part of my personal life.
