How many documents can I cross-reference at once?

You can upload a primary document and compare it against a secondary reference document to identify discrepancies, missing clauses, or conflicting information between the two.

Does this tool just do a simple text difference comparison?

No, unlike a standard 'diff' tool, our AI understands context. It can identify if the same concept is discussed using different terminology or highlight if a critical topic from Document A is entirely missing from Document B.

Is this useful for comparing different versions of a contract?

Absolutely. It's highly effective for version control, allowing you to ensure that negotiated changes were actually implemented and that no unexpected alterations were sneaked in.
