Isaacus enrichment outperforms everything we've tested, from the biggest LLMs down to static extraction methods. It's the most accurate way we've found to turn unstructured legal documents into structured knowledge graphs, and we couldn't be happier with it.

Kanon 2 Embedder and Reranker have been rock-solid in production. They handle Danish legal text remarkably well and are a perfect fit for a complex search engine like Lovguiden.

Webb Henderson is walking its own path on legal AI and Isaacus has been a key enabler of that strategy. Their enrichment, classification, retrieval and extraction tools have let us build a world-class legal AI capability. We're excited to deepen the partnership as Isaacus moves into legal research with the Blackstone Graph.
