Show HN: Kanon 2 Enricher – the first hierarchical graphitization model

3 days ago

Kanon 2 Enricher is the world’s first hierarchical graphitization model, transforming unstructured documents into structured knowledge graphs with sub-second latency.
Isaacus Legal Graph Schema (ILGS) is released, a knowledge graph schema for legal documents, available under CC BY 4.0 license.
Kanon 2 Enricher is available via Isaacus API and has been tested by notable firms like Harvey, KPMG Law, and Clifford Chance.
An interactive 3D map of Australian High Court cases since 1903 was created using Kanon 2 Enricher and Kanon 2 Embedder.
Kanon 2 Enricher can extract, disambiguate, and link entities, deconstruct document hierarchies, and annotate text without generative hallucinations.
The model is computationally efficient, running locally on consumer PCs, outperforming LLMs like Gemini 3.1 Pro and GPT-5.2.
Applications include financial forensics, legal research, and regulatory analysis, with real-world use cases from the Isaacus Beta Program.
Kanon 2 Enricher’s architecture includes 58 task heads and 70 loss terms, enforcing strict schema constraints.
Future plans include the Blackstone Graph, a public legal knowledge graph, and Kanon 3 Enricher with custom extraction support.
Kadi, the first legal reasoning model, is expected by the end of the year.
