Complete Discovery Source adds custom AI analyses in Relativity aiR for Review

Complete Discovery Source on Aug. 25, 2026 said it is expanding its AI offerings with custom analyses in Relativity aiR for Review, a no-code tool for legal document review. The feature is designed to help legal teams define their own analyses in plain language, run them across large document sets and keep outputs defensible within existing RelativityOne workflows.

Why it matters: - Legal teams can now build AI-driven review workflows around the specific questions in a matter, rather than relying only on predefined categories. - The update is aimed at helping teams handle document review, fact investigation, data extraction and image analysis at scale without adding technical complexity. - The feature is included in the standard RelativityOne subscription, which lowers the barrier to adoption for existing users.

What happened: - Complete Discovery Source announced the expansion of its AI offerings with custom analyses in Relativity aiR for Review. - The announcement was made Aug. 25, 2026 in New York. - The no-code feature lets legal professionals define, deploy and scale document review analyses in plain language. - CDS said the tool works across entire document sets without coding or technical configuration.

The details: - Custom analyses help legal professionals identify and classify key content across millions of documents. - Teams can create analyses for document classification, data extraction and image analysis. - The platform includes an iterative prompt experience so teams can test and validate outputs before running at scale. - CDS said the capability works within clients’ existing RelativityOne environments. - The company said the feature operates inside existing workflows and does not require a separate tool. - CDS said its experience designing and managing RelativityOne workflows helps clients adopt the new capability while maintaining consistent, defensible processes. - Relativity’s purpose-built analyses remain part of the platform alongside the new custom option. - The company directs readers to more information on the CDS partnership with Relativity.

Between the lines: - The release positions CDS as a services partner that helps legal teams move from general-purpose AI features to matter-specific review strategies. - The emphasis on defensibility, validation and workflow continuity reflects the legal sector’s focus on review quality as well as speed. - By pairing custom analyses with RelativityOne, CDS is trying to make advanced AI feel like an extension of existing review operations instead of a separate technology project.

What's next: - CDS said clients can begin using the new capabilities within their existing RelativityOne environment. - The company is expected to use the feature to broaden AI support across review and investigative workflows for legal matters. - CDS will continue promoting its partnership with Relativity as part of its legal data solutions offering.
