I always thought one of the best promises of AI was to be able to feed it a 'jargon heavy' document (business contract, corporate policy, congressional bill, etc.), and have it spit out the real meaning in plain language.

"Don't sign this because you are screwed if x, y, or z happens!" would be a good summation in many cases.

Has anyone had much success with this kind of AI interaction?

I've generally found it better at doing the opposite: taking readable, concrete terms and obfuscating them into LinkedInish.

In this study it was randomly generated phrases.
