There's now a website that allows you to upload research papers and use AI to answer questions.
So basically you upload the paper, and you're allowed to ask questions based on the contents.
I've only quickly uploaded some test papers and looks promising. It looks like it's relatively new and is a bit slow so there may be future releases to improve on it.
You're allowed to have a restricted free account with so many uploads etc.

Might be worth checking it out. It could potentially help understanding research papers by explaining results in layman's terms.
Hope it helps.
