It's not just for people doing interesting things. It just helps people answer questions about stuff. The stuff can be interesting or boring or dangerous or silly. The last question I tested the ACH tool on was "Did William Shakespeare really author all of the works he was credited for?" - You can use this stuff to research whatever you want. That's the point of it - it's no one's business what you are interested in getting to the bottom of.

Description on the repo says it's for journalism, but I build similar rigs that I use for research in companies that have entered bankruptcy proceedings.

Commonly there is a lot of information and it might as well be unstructured, and then I need to get answers quickly because my clients aren't going to pay me for going about it slowly.
