This seems pretty possible with a GPT powered tool, now.
You could ask it a question, it then performs a bunch of searches, checks the results, assesses the results, and puts the most relevant stuff into a one page report.
I'm guessing a few HNers are working on this.
Who is working on it, and does anyone have a demo we can play with?
You're missing too many variables and focusing too much on what you want without realizing what is actually possible.
