What it is

It parses contracts to output severity-rated risk assessments, key terms tables, market benchmarks, and specific redline language. It also handles missing provisions and internal consistency checks across NDAs, SaaS agreements, and M&A documents.

Who it's for

It suits developers, legal professionals, and technical founders who work with contracts inside AI coding assistants. It does not suit non-technical users who require a standalone graphical software application without command line tools.
