Luminance Discovery uses next-generation AI to enhance and expedite a range of investigations, arbitrations and litigation matters, from eDiscovery and Early Case Assessment (ECA) to requests for personal information such as Data Subject Access Requests (DSARs).

AI Powered Analysis: Luminance’s AI reads and forms a conceptual understanding of documents, representing this analysis across a series of interactive widgets and 3D visualisations, helping lawyers to quickly find what they are looking for.

Early Case Assessment: With AI-powered ECA, lawyers can quickly and easily apply powerful searches and filters to cull irrelevant documents and find what matters. Luminance understands documents on a conceptual level, allowing lawyers to search for conceptually similar documents to the one under review in just one click. 

Technology Assisted Review: Luminance’s AI can observe the coding actions of the team and then flag where the coding of a document appears anomalous compared to how similar documents have been coded in case this warrants a further review. Luminance can also predict how relevant as-yet uncoded documents will be, ensuring lawyers can focus their time effectively.

Conceptual Understanding: With no prior training needed, Luminance’s heatmap organises the entire dataset by conceptual similarity, with each tile representing conceptually alike documents. The depth of colour of each tile illustrates how many of these documents have been reviewed, making sure lawyers can allocate resources to under-investigated areas quickly.

PII Detection: Luminance can detect Personally Identifiable Information (PII) and redact all examples of certain critical and confidential types of information, for example, users could redact all addresses across their entire project.
