It learns from you.
At first it helps you by giving you all kinds of headlines and phrases and words applicable to the situation.
As time advances, it learns "how" you like to phrase things, who and what you know, and gets better at giving you relevant suggestions.

I'm not talking about summarizing a whole page of text. Just a phrase.
Example: "I need to give the book back to the library tomorrow morning."
Summarize: Action: Set event in calendar: Confirm Time: tomorrow morning: Default to 10, but ask if thats ok. Headline: Library: Ask which. Choose from short list Ambiguities: - bookname: ask. - if doesn't know set reminder to find bookname: Confirm with option to cancel (as not important) .-- pashute, Sep 07 2022 Thinking is hard.
