Overview

Relativity, launched in 2001, built its reputation on document management and review during litigation discovery long before generative AI existed, and has since layered AI-assisted review and analysis capabilities onto RelativityOne, its cloud platform running on Microsoft Azure.

That two-decade head start shows up in scale: legal teams use Relativity to organize, review, and analyze the massive data volumes involved in complex litigation and investigations, a use case distinct from the personal-injury or contract-drafting focus of newer legal AI entrants like Harvey or EvenUp.

Pricing runs on enterprise contracts scoped to data volume and user count, standard for e-discovery platforms operating at this scale. For a legal team managing e-discovery and investigations involving large data volumes, Relativity's established, AI-augmented platform addresses that directly.
