What exactly do the questions do and what are they for?

The questions allow the end user to answer a question. The answer to this question will be sent to the LLM in order to provide additional information that may be required for it to complete its review.

Imagine for example that you are reviewing a license agreement and that you want the AI to make sure that the liability cap is limited to 20x the monthly license fees.

What if the monthly license fee is not set out in the document? Then the AI has no way of knowing how to respond to that question. In this case, it can help if the AI can pull in that information directly from the user.
