Luminance is an AI legal document review platform used by over 500 law firms and legal departments globally for high-volume document review tasks — M&A due diligence, contract portfolio review, regulatory compliance review, and litigation document review. Its foundation is a machine learning model trained specifically on legal documents to understand the structure and content of contracts and legal agreements.
The diligence capability processes large volumes of contracts and extracts key provisions, flags unusual terms, and presents a structured overview of a deal's legal exposure — work that would traditionally require teams of lawyers reviewing documents manually. M&A transactions with hundreds of contracts become manageable in a fraction of the time.
Luminance AUTOPILOT is the most distinctive feature — AI autonomous negotiation of standard contract types (NDAs, standard commercial agreements) where the AI identifies issues in incoming contracts, redlines them based on the organisation's preferred positions, and can complete the full negotiation lifecycle with minimal lawyer involvement for straightforward agreements.
At 500+ customers including Linklaters, A&O, and Hogan Lovells, Luminance has strong enterprise law firm validation and competes directly with Kira Systems and Evisort in the contract review and diligence space.
Luminance AI runs as document analysis llm software built around text and document workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web.
