It would be great if one could come up with a human interface to Mathematica documentation (or possibly this site) in the spirit of ChatGPT? 

We have Wolfram alpha to answer direct mathematical questions in plain language but it is not (?) directly interfaced to the language's help system which is becoming a bit big to browse.

At some stage this is a question for Wolfram but...
>  can we as a community define the precise requirement of such an interface? Or write a prototype which grep within the documentation?

The output could be as extensive as Wolfram alpha.


In some sense this question is  the opposite of that [answer][1] which gives details beyond what is in the (standard) documentation.
