RelativityOne

RelativityOne is Relativity's cloud-based SaaS platform built to help legal teams organize complex data, uncover critical information, and act with confidence. Developed by Relativity—a Chicago-headquartered company with offices in Kraków, London, and Sydney—the platform has served the legal industry for over 25 years, according to the company's website. It targets law firms, corporate legal departments, federal and state agencies, litigation service providers, and cyber insurers.

What It Is

RelativityOne is an AI-powered legal intelligence platform that consolidates e-discovery, document review, legal hold, contract review, early case assessment, and data breach response into a single cloud environment. It is the SaaS successor to Relativity's on-premises software, and Relativity actively encourages existing on-prem customers to migrate to it. The platform is FedRAMP-authorized for government use and is positioned as the primary product in Relativity's portfolio.

The Relativity aiR Suite

A core differentiator of RelativityOne is the built-in Relativity aiR family of generative AI products, each targeting a specific legal workflow:

• aiR for Review — AI-assisted document review to surface relevant materials faster
• aiR for Privilege — Automated identification and logging of privileged documents to reduce clawback risk
• aiR for Case Strategy — Generates actionable insights to sharpen litigation strategy
• aiR for Data Breach Response — Accelerates identification of sensitive data in breach incidents
• aiR Assist — Described on the site as "coming soon," focused on uncovering hidden insights

The company states that aiR for Review, aiR for Privilege, and aiR for Case Strategy are included in the RelativityOne platform at no additional cost.

Platform Capabilities and Use Cases

Beyond the aiR suite, RelativityOne covers the full legal data lifecycle:

• Legal Hold — Defensible, repeatable preservation workflows
• Collection — Native data collection including a recently announced integration with the Claude Compliance API for collecting Claude Enterprise data, alongside existing support for ChatGPT and Gemini enterprise data
• Early Case Assessment — Pre-review data culling and analysis
• Second Requests — Regulatory merger review support
• Contract Review — Complex contract analysis via Relativity Contracts
• Investigations — Internal and external investigation support

The platform also offers the Relativity App Hub, an ecosystem of third-party and custom applications for specialized data challenges.

Integrations and Ecosystem

Relativity maintains a strategic technology partnership with Microsoft and has announced a Purview Sync feature enabling direct, automated data transfer from Microsoft Purview eDiscovery (Premium) to RelativityOne. The platform natively collects data from Claude (Anthropic), ChatGPT (OpenAI), and Gemini (Google), covering the three leading enterprise AI tools according to Relativity's blog. Audio and video transcription is available natively within the platform, converting A/V files into searchable text.

Audience and Deployment Model

RelativityOne is delivered as a cloud SaaS platform, removing the infrastructure burden from customers. Relativity targets a broad legal market including AmLaw 200 law firms, Fortune 500 corporations, federal agencies, state and local governments, and academic programs. The company offers a dedicated academic program providing hands-on legal technology experience for law, paralegal, forensics, and data science students. Relativity also maintains a global partner network of service providers and offers a partner portal, partner learning resources, and a partner program with defined roles and benefits.

Update: Claude Integration and Recent Capabilities

Relativity's blog and homepage highlight several recent product additions. The Claude Compliance API integration—announced via press release—enables native collection of Claude Enterprise conversation data, completing coverage of all three major enterprise AI platforms. The Purview Sync feature provides a direct pipeline from Microsoft Purview eDiscovery (Premium). A/V Transcription was added natively to RelativityOne, making audio and video content searchable within the platform. Anthropic also announced 20+ connectors for the legal industry, including one allowing Claude to interact directly with RelativityOne for administrative tasks. These updates signal an active product roadmap focused on expanding AI data sources and deepening generative AI capabilities within the platform.
