Project Overview
Contract redlines are easy to miss in a wall of legal text. ClauseLens diffs an original and a revised contract, scores each change by risk, and explains what actually changed and why it matters, in plain language, not legalese.
Upload both versions, click analyze, and get back a structured risk report with a clear recommendation per change instead of a raw redline you have to interpret yourself.
