What does LLM Sandbox by Dioptra do?
LLM Sandbox by Dioptra is an AI-powered contract review tool that automates the redlining process in Microsoft Word. It analyzes legal documents against your custom playbooks, executed agreements, and standard forms to generate precise redlines that reflect your organization's specific legal requirements. The tool works directly within familiar Word workflows, eliminating the need to switch between different platforms or learn complex new software.
What sets LLM Sandbox by Dioptra apart is its remarkable accuracy—achieving 95% accuracy on your paper revisions and 92% on counterparty papers according to their testing. The system can distill custom playbooks from your existing materials, search and extract terms across your contract portfolio, and generate comprehensive issues lists and risk summaries. It also includes a secure AI assistant for quick contract-related questions and offers enterprise-grade security with SOC2 Type II compliance and private LLM deployment options.
This tool primarily benefits legal professionals, contract managers, and enterprise legal teams who regularly review agreements. Real-world use cases include accelerating contract negotiations by generating initial redlines in minutes instead of hours, maintaining consistency across organizational contracts, and quickly identifying non-standard terms in counterparty documents. Large law firms and corporate legal departments report saving up to 80% of their contract review time while maintaining high quality standards.
