About

Isaacus is a foundational legal AI research company.

We build legal AI models for legal tech companies that help them ship smarter products, faster.

Our core offering includes soon-to-be-released state-of-the-art legal embedding and legal reasoning models, alongside our already-in-use lightweight legal classification and text extraction models.

We’re also proud supporters of open legal data and software, maintaining the Open Australian Legal Corpus, the only open database of Australian law, as well as semchunk, the world’s most popular semantic chunking library, downloaded over 600k times a month.

We acknowledge the Wurundjeri people, and pays respect to their elders, past and present, who are the traditional owners of the unceded land on which Isaacus is based.

We honor the memory of Sir Isaac Isaacs and all those who fight for justice.
