RelativityOne (often called RelOne) and Everlaw are cloud-based eDiscovery platforms used to manage electronic evidence in litigation and investigations. Both support review, analytics, collaboration, and production. Their differences are better understood as workflow and implementation considerations, not a universal judgment that one is superior. This article compares published capabilities, identifies practical trade-offs, and suggests questions to ask during a demonstration.

Predictive coding is a technology-assisted review (TAR) method that learns from human reviewers’ document decisions and uses those examples to rank or classify other electronic documents. Rather than reading every document in arbitrary order, a review team can focus first on documents the model predicts are more likely to matter. It is a workflow combining legal judgment, software, and quality control; not a substitute for the legal team.
