Section 4 of 12

Inconsistent term

Definitions — 6.2

AI proofreading checks a legal document for internal errors that are easy to miss: broken cross-references, inconsistent defined terms, numbering gaps, contradictions and language mistakes. CASUS Proofread does this section by section and fixes each issue as a tracked change in Word.

CASUS Proofread checks cross-references, clause numbering, the consistent use of defined terms, contradictions between provisions, and spelling and language. Every finding names the type of issue and comes with a correction.

Proofread checks whether a document is internally correct and consistent. Risk Review assesses legal and commercial risks from the perspective of the party you represent. Both use the same section-by-section engine and work well together.

You apply a correction with one click, either as a tracked change or directly in the document. You can also edit or skip every proposal, so nothing changes without your approval.
