Yochai is a Socratic AI "chevruta" or learning guide, powered by a foundational library of 1,000+ primary sources from the Jewish canon, (and a knowledge graph of 2.5M entities, and 16M entity relationships, 375,000 searchable passages, and 17,000 canonical concepts that we developed around our own ontology). Yochai, uniquely, takes you directly to the sources and pushes you to discover and articulate your own insights about them.

we open sourced our knowledge graph so others can build on our foundation
