THE GOOD:
I haven't seen anything else quite like this tool, which can combine several documents for review and analysis.

THE BAD:
The results can be insightful, but can also be EXTREMELY UNRELIABLE. It will get simple things like page numbers dead wrong. You'll correct it, and it will provide some indication that it is learning ("...I won't make that mistake again...") and then it will immediately make the same mistake. In my experience it gets page numbers wrong more than half the time. It's still a net positive. It provides good summaries, but make sure you know the gist of everything it's reviewing...you'll have to do A LOT of manual QC.
