Dioptra: AI Contract Redlining Add-In for Word

Dioptra brings AI-powered contract redlining straight into Microsoft Word, letting legal teams draft, compare, and review agreements against playbooks in seconds.

Overview

Dioptra is an AI redlining assistant built directly into Microsoft Word, designed to take the manual grind out of contract review. Instead of jumping between tools, legal teams can prompt the assistant to compare clauses, research precedent, draft language, and redline documents against playbooks, executed contracts, standard forms, or past examples—all without leaving their familiar Word environment. This makes it especially useful for high-volume agreements like NDAs and MSAs, where consistency and speed matter. By combining natural language prompts with structured playbook logic, Dioptra bridges the gap between rigid template-based review and fully manual redlining. It can flag gaps against a company's standard positions, extract key terms automatically, and suggest edits in real time, effectively acting as an always-on junior associate embedded in the document itself. For teams managing repetitive contract lifecycle tasks, this can dramatically cut turnaround time while improving consistency across reviewers.
