For the past month or so I've been slowly having claude build something in the same ballpark. Basically something to nag you to take care of grown-up things so your boss/spouse/local municipality doesn't have to.
I was going to call it "Nagatha Christy", but the joke gets old after 48 hours. At the moment, its called "Jarbis" (old Simpsons reference).
For me, checklists are useful but I suck at creating them, maintaining them, etc. I want this thing to be able to look at my calendar/email/groupme and be able to say things like:
"Hey, you have 2 kid birthday parties this weekend and a soccer game - you're bringing snacks. You want me to update your shopping list?"
or
"The dentist office just sent out a reminder - you have an appointment on Thursday that's not on the calendar. It conflicts with your daily standup. You want me to create a task for you to resolve it?"
Its using: - AWS CDK - Telegram as primary chat interface - Trello/Jira/Something Custom - Integrations into GoogleCalendar and GMail - Ability to use Claude/OpenAI and different models
FWIW, if someone figures out how to create a reliable "secretary in a box" that I don't have to DIY but doesn't scream data-collection-watering-hole (facebook) I'd _happily_ pay $200 / mo for it. ;-)
