Clausio is a Microsoft Word plugin for contract review. It compares the client's version against your firm's template, highlights every change, and flags risky clauses by severity — critical, high, medium, low. For each flagged clause, it generates a counter-proposal in legal language, ready to approve or edit. No copy-pasting. No switching apps. Everything happens inside Word's task pane. Lawyer approves every suggestion before anything changes. Free 14-day trial for law firms.
