What is Document Diff Analysis?

Mechanical comparison is solved; interpretive comparison is not. Knowing that a paragraph changed matters far less than knowing that a liability cap moved, a deadline shortened or an exclusion appeared — and the second requires understanding what the text does rather than how it reads. This is where AI assistance is genuinely valuable and genuinely risky, because a missed material change is worse than no summary at all. Where Centralpoint's AI layer summarizes a comparison, the versions retrieved and the rules that governed the analysis are retained with the answer, so a reader can check the summary against the underlying text rather than accept it. Governance-tier skills can require escalation on document classes where a missed change carries real consequence, which keeps the assistance bounded — the reviewer remains accountable for the document rather than for the summary they were shown.
