What is Relativity?
A litigation team receives a preservation notice on a Monday morning — 4.2 million documents from a former employee's email archive, Slack export, and shared drive. Without a structured review platform, identifying the relevant 3% of documents in time for a discovery deadline would require hundreds of attorney hours. Relativity is the platform most Am Law 200 firms reach for in that moment. Relativity is an AI-powered eDiscovery platform used by law firms, corporate legal departments, Fortune 100 companies, and federal agencies including the U.S. Department of Justice to organize, search, and review large data sets across litigation, internal investigations, regulatory requests, and data breach response. RelativityOne, its cloud-based SaaS product, uses consumption-based pricing charged per GB of data per month with no per-user seat fees — a model verified in April 2026 across independent sources, with costs ranging from approximately $500 to $25,000 per month depending on data volume and commitment tier. Pay-as-you-go, one-year, and three-year flex commit options are available, with volume discounts on longer commitments. The platform's generative AI layer, Relativity aiR, assists attorneys with document relevance assessment, privilege review, and issue identification — generating rationale for AI recommendations that reviewers can evaluate rather than simply accept. The most recent IDC MarketScape report positioned Relativity as a Leader in global eDiscovery vendor evaluation. RelativityOne is available in 17 countries with 24/7/365 human support and the largest ecosystem of third-party service provider integrations in the eDiscovery market. Relativity is not the right tool for organizations with straightforward document storage or basic legal management needs. Law firms handling standard transactional work, contract management, or practice management without significant litigation discovery volume will pay a premium for capabilities they will rarely use — purpose-built contract review tools or standard document management platforms are more cost-efficient for those workflows.
Relativity is an AI eDiscovery platform trusted by Am Law 200 firms, Fortune 100 corporations, and the U.S. DOJ to manage document review, legal hold, and case analytics at scale.
Relativity is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.

Final Verdict
For corporate legal departments and Am Law 200 firms managing high-stakes litigation with data volumes in the tens of millions of documents, Relativity's AI review tools and 24/7/365 support structure compress the manual attorney hours required for relevance and privilege review — a measurable ROI driver when associate billing rates are the primary cost lever in document review projects. The limitation to flag for smaller firms is cost transparency: Relativity's consumption-based pricing requires careful data volume forecasting to avoid unexpected cost escalation mid-matter, and the per-GB model can make smaller or intermittent matters more expensive per document than anticipated.
