Legal AI for problems, not pitch decks
Legal doesn't need more chatbots. It needs tools that integrate with what lawyers already use and solve real problems. We start with the fundamentals everyone ignores: formatting, error checking, consistency. Then we build outward, leaving no aspect of legal drafting unaddressed.
