What is Luminance?

Luminance is a leading legal AI platform that uses specialized language models to analyze, draft, and manage legal documentation. The technology automatically processes contracts, due diligence materials, and eDiscovery data while highlighting risks, anomalies, and clause deviations. In-house legal teams and law firms use the platform to drastically accelerate workflows and streamline legal operations.

At its core is Lumi, a proprietary legal LLM trained specifically on legal texts to deliver deep contextual understanding. Luminance supports the complete contract lifecycle, from initial drafting and negotiation to post-execution repository management. With seamless integrations into tools like Microsoft Word and email clients, it fits directly into established legal workflows.

Beyond contract analysis, Luminance provides powerful eDiscovery and compliance auditing capabilities for M&A transactions and litigation. The platform identifies anomalies across vast document sets and automatically categorizes clauses against predefined corporate standards. This helps organizations minimize legal risk while reducing the time spent on routine document reviews.

Typical use case

An enterprise legal department preparing for an acquisition needs to audit hundreds of supplier contracts for change-of-control and liability terms.
