We make legal AI models that are effective. efficient. scalable.

We’re setting the standard for effective, efficient, and scalable foundational legal AI — one model at a time.

We lead the pack in foundational legal AI.

Our flagship Kanon 2 Reranker and Kanon 2 Embedder models are the most accurate legal information retrieval models in the world. Together, they rank first on Legal RAG Bench and the Massive Legal Embedding Benchmark (MLEB).

Our Kanon 2 Enricher model is the first ever hierarchical graphitization model, capable of transforming unstructured documents of any length into rich, highly structured knowledge graphs with sub-second latency.

We’re also the creators of semchunk, the world’s most popular semantic chunking algorithm, used by Microsoft, IBM, The World Group, and Docling.

We solve real problems.

Guided by our own frustrations working in the legal tech industry, we’re focused on solving the most time-consuming problems legal tech professionals face each day.

Whether it’s as simple as pulling dates from contracts or as complex as searching thousands of cases for a critical citation, we’ve either got a model ready or have already working on one.

Retrieval

Turn complex legal queries into highly relevant search results with Kanon 2 Embedder and Kanon 2 Reranker, our state-of-the-art legal retrieval models.

Enrichment

Transform unstructured documents of any length into rich, highly structured knowledge graphs with Kanon 2 Enricher, the first hierarchical graphitization model.
