Extract
Entities, relations, semantic types, source spans, and training annotations.
Start here
Start with Leyli Biomedical Knowledge Engine.
Analyze biomedical documents, inspect ontology-grounded knowledge, and explore the controlled concept layer that supports trustworthy AI. The Biomedical Demo is the main workflow; the ontology workspace lets you see how concepts, hierarchies, relationships, and terminology support the engine.
Recommended path
1. Load sample or upload2. Select UMLS/SNOMED CT3. Analyze4. Inspect graph and evidence5. Export GraphRAG/API outputs
Ontology workspace
The Ontology Studio is Leyli’s supporting workspace for browsing controlled vocabularies, concept hierarchies, relationships, and multilingual terminology. It makes the semantic layer behind the Knowledge Engine inspectable.

What you will see
A working Knowledge Engine with an inspectable ontology layer.
Biomedical is the first public proof because it demands precision, terminology, ontology grounding, and source evidence.
Ground
UMLS and SNOMED CT concept context for biomedical terminology.
Inspect ontology layer
Browse concept details, hierarchies, relationships, and multilingual labels that support ontology-grounded analysis.
Deliver
GraphRAG packages, JSON/CSV/GraphML exports, ETL outputs, and API-ready structures.
