Ontological Legal Research is now live in the US, after Legora described the approach in September. It pairs primary law Legora collects directly, including slip opinions from court websites within 24 to 48 hours, with a prebuilt ontology linking defined terms to the cases that interpret them, overruled cases to the decisions that overruled them, and rules to their exceptions. Legora says the structure makes its Agent 40% faster on an internal set of thousands of research questions, and its AI native citator comes next.
Buyer relevance. Research grounded in how authorities relate to each other, not just text similarity, is a direct answer to AI citing overruled law. The 40% figure measures speed on Legora's own test set, so buyers should ask for accuracy results too.
