This is what I mostly want. I want to keep track of things and when I have half done the work I want to note that and split the to-do and things like that. I want to say things to notes and have it write it down like me. I use Reminders app with my wife and use LLM to manage it. This would make me end up using Notion for personal life perhaps, but it has to be good. Problem with first-party agent is that I'm stuck with garbage agent because either:

* they have decided to "have our own model" (always garbage model)

* they have decided to "collaborate with X" (and this model rapidly gets outdated)
