Two approaches to CLM

Summize delivers a full AI-powered CLM platform, supporting the entire contract lifecycle from intake and drafting to negotiation, execution, and ongoing management.

FAQs
No – Luminance is primarily an AI-drive contract analysis and review point solution. It excels at due diligence and bulk review but lacks the workflow orchestration needed for a full contract lifecycle. Summize is a comprehensive CLM platform designed to manage the entire journey of a contract, from initial intake and automated triage to drafting, signature and renewal.
Luminance focuses on document analysis rather than active lifecycle management. Summize provides a proactive contract repository that includes automated obligation tracking, renewal alerts and spend management. This ensures that once a contract is analyzed, the data is used to prevent revenue leakage and ensure compliance, which standalone review tools can’t do.
Luminance is a specialized tool used almost exclusively by legal teams for deep analysis. Summize is built for frictionless workflows, enabling teams like sales and procurement to interact with contracts directly in the tools they already use, like Microsoft Teams, Outlook, Slack, Salesforce and more. This cross-functional adoption means that legal oversight is embedded in the business, rather than being a bottleneck in a separate analysis tool.
Yes. While Luminance focuses on review and analysis, Summize provides contextual AI that powers the whole workflow. This includes instant contract summarization, AI-powered clause extraction and automated risk scoring – Summize doesn’t just analyze the contract, it uses that intelligence to accelerate approvals and simplify negotiations.
Luminance is a fit for one-off projects like M&A due diligence or massive litigation reviews where deep discovery is the priority. However, for day-to-day operations, Summize is the better option. If you need to manage high volumes of contracts, improve business-wide adoption and automate the end-to-end lifecycle from request to renewal, Summize provides the operational infrastructure that analysis-only tools lack.
