I look up some information about a service provided by some institute and wish to create a task, reminding me to call them up this morning and make an appointment. Later on, I will want to turn it into an event with time and location.
The smart assistant gathers all the info and creates a structured
text, which could be read by any person, or presented nicely in an app or browser add-on.
When I create the reminder task it already knows the title, and puts the structured info into the details. And when I create the event all the fields are correctly filled.
The smart paste can also work by presenting you the options of all current info, with the default being what seems to be the correct option.
The text can be in a hierarchical structure so that when there are multiple telephone numbers for instance, each will have a "label" of what it is. AI can help determine from the web page what kind of phone it is, mobile or landline, and whose number it is.
The same goes for creating bookmarks or filling in a bibliography as a researcher.
If there is highlighted text it can also store the beginning and end of the text for reconstruction as a link to highlighted text.
The important part of this idea is that the clipboard contains text which can be used in a smart app, to easily fill in fields in forms and to set up services without going back and forth between the copied screen with the information, and even not having to navigate again and again through different pages of results, with your flight date and number at one URL, and your frequent flying points retrieved from a different page. (And your personal info in a third, private, page)
