What Features Would You Like to See in an AI Daily Planner?

You'd have to prove to me that I could trust it first - with the high rate of hallucination and other general inaccuracies in ai outputs that I've seen, they ain't gonna cut it.

Even 95% accurate isn't enough if it means missing a meeting I was supposed to be at or a task I was supposed to do, or wasting time running around trying to find out about the damn meeting I've been prompted to attend, which doesn't exist.

We are developing an AI-powered day planning platform with features like AI-generated to-do lists tailored to your calendar, automatic creation of subtasks, conversion of tasks into actionable steps, and ambience generation. When you first hear "AI daily planner," which feature would you expect to be powered by AI?
