We lead the pack in foundational legal AI.

Our flagship Kanon 2 Embedder model is the most accurate legal embedding model, ranking first on both Legal RAG Bench and the Massive Legal Embedding Benchmark (MLEB).

Kanon 2 Embedder is 26% more accurate at legal information retrieval than its most widely used general-purpose competitor, while remaining 30% faster.

We’re also the creators of Kanon 2 Enricher, the first hierarchical graphitization model, and semchunk, the world’s most popular semantic chunking algorithm, used by Microsoft, IBM, The World Group, and Docling.
