What RelativityOne is

RelativityOne is a vendor cloud platform for legal work, including litigation, investigations, and other legal data challenges. It supports e-discovery from collection through production, with review tools for emails, spreadsheets, chats, prompt-and-response conversations, and PDFs. Review work can use a native file viewer, email threading, and automated redaction. Productions can be prepared as TIFF, text, metadata, load files, or native files with placeholders.

Administrators can manage permissions for users, system administrators, workspaces, and individual objects such as views, tabs, and fields. Security Center, a monitoring application, is included. Relativity says its claiR, Assist, aiR Review, Privilege, and Case Strategy capabilities are included with committed data volume, with no separate AI licenses or per-user fees. The platform can be extended through open APIs, App Hub, and its partner ecosystem; MCP connects external AI applications including Claude, Gemini, Copilot, and GPT Enterprise.

RelativityOne is available on web, Windows, macOS, iOS, and API, and customers can choose data location in 17 countries. Licensing is pay as you go or based on one- or three-year commitments. Pricing is on request; Data Breach Response, Translate, FOIA, and Legal Hold are licensed separately.
