Discovery in the LLM Era: 10 Million Documents in an Afternoon

Reveal Brainspace and Relativity aiR have made document review a different job. Litigators describe the new workflow.

Document review used to be the first job for any law school graduate — a rite of passage measured in late nights and contract-attorney hourly rates. In 2026 it is an LLM job, with a partner-tier lawyer reviewing the model's flagged subset and signing the privilege log.

Reveal Brainspace and Relativity aiR both ship continuous active learning workflows that converge on responsive document populations in hours rather than the weeks that traditional technology-assisted review required.

The defensibility question has turned out to be more tractable than the early skeptics predicted. Every retrieval, every model version, every prompt template, and every reviewer adjudication is logged in a way that opposing counsel can subpoena.

The downstream effect on legal hiring pipelines is starting to register at the law school level. The traditional entry-level associate work that subsidized first-year salaries is being structurally hollowed out.
