That's the lawyer's job, to guide you through ! If they're not doing that, then find a different lawyer.

The whole point is we are talking about legal document review here.

Reviewing legal documents necessarily involves an active discussion with a lawyer, it is not something you can turn up with pre-prepared questions for.

A 100 page legal document (i.e. one with lots of stuff implied by structure and lots of specific subconditions and lots of case-specific stuff that might make more sense in conjunction with the examples in the appendix) sounds like the sort of thing AI would be wrong about far more often than it was right...

At least reading a short contract or EULA I'd be pretty confident an AI-based system would have lots of similar contracts and plain English explanations in its corpus and correctly identify the boilerplate exclusions and even if it misinterpreted stuff like IP assignments and ability to modify the agreement it might be slightly better than Ctrl-F at figuring out which clauses do this. Although from what I can see the current incarnation is working on a paragraph by paragraph basis so doesn't even necessarily apply definitions defined in the section above correctly...
