Isaacus

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

Isaacus is a legal artificial intelligence research company building AI models for the legal technology industry.

Our products include Kanon 2 Embedder (the world's best legal embedding model), the Massive Legal Embedding Benchmark (MLEB) (the world's largest legal embedding benchmark), and semchunk (the world's most popular semantic chunking algorithm, used by Microsoft, IBM, and the World Bank).

Our models can be accessed via our online platform or through self-hosted enterprise deployments.

Follow us on LinkedIn and Reddit to say up-to-date on our latest news.
