My wife and I have a shared family calendar through iCloud for appointments, events, kid stuff. One of us (I won’t say who) doesn’t always keep it up to date.
I want a family agent that you can text something like “School meeting at 6pm next Tuesday” or even just forward a screenshot of a school flyer, and it parses the details and adds it to the shared calendar automatically. Just text it like you’d text your spouse and it shows up on the calendar.
