looking for: AI-driven copy scraper/analyzer

Problem:
"MVP just made $1000 a month" - when you see that on a basketball website it means something very different than when you see it on indiehackers ;)

Now I'm looking for a tool where I can enter a website or forum and it gives me a better idea of what "version of English" they use: Uncover technical terms, frequently used language etc.

The reason is simple: I've found it easier to explain what I'm working on by listening to individual people first and then describing it in the language they use. I'd like to apply that when posting in forums as well.
