Relativity DISCO Everlaw Own the Corpus

The real moat here is not the AI feature, it is owning the evidence set before strategy work begins. Relativity, DISCO, and Everlaw already sit where litigation teams load, review, search, and tag the documents for large matters, so when they add timelines, witness summaries, deposition summaries, and draft writing, they are generating strategy from the same corpus lawyers already trust and pay to manage. Crimson is strongest earlier in the dispute, before a matter hardens into full eDiscovery workflow.

• Relativity has the clearest inside the review room advantage. aiR for Case Strategy runs inside RelativityOne, turns saved searches into fact chronologies, and then reuses those facts for witness summaries and deposition outlines. Relativity has disclosed more than 1 million documents processed and more than 800,000 facts extracted.

• DISCO is pushing the same play across review and case prep. Cecilia Q&A answers questions against the live eDiscovery database with inline citations, while Case Builder adds AI timelines and deposition summaries. DISCO also layers in Auto Review, so evidence finding and first pass review stay in one operating environment.

• Everlaw is coming from a slightly more open angle, but the core logic is the same. Its AI tools sit on top of Storybuilder, review, ECA, and larger data set analysis, so teams can move from collecting documents, to finding evidence, to drafting memos and outlines without exporting the record into a separate workspace.

This market is heading toward litigation systems where document review, factual investigation, and case theory formation collapse into one loop. The winners will be the platforms that become the default home for the record, because once the corpus lives there, every new AI workflow becomes easier to adopt and harder to displace.
