eDiscovery platforms manage the electronic discovery process for litigation and investigations — collecting, processing, reviewing, and producing electronically stored information (ESI) in response to legal holds, regulatory requests, and litigation obligations. Core capabilities include data collection from email, cloud, mobile, and enterprise systems, data processing and deduplication, AI-powered document review (technology-assisted review / TAR / predictive coding), privilege detection, production formatting, and audit trail documentation for defensibility. The category spans enterprise eDiscovery suites (Relativity, Everlaw, Reveal, Nuix) and managed eDiscovery service providers that combine platform with review services.
