Medical team using a Leyli knowledge graph
Biomedical knowledge engine demo Leyli Biomedical Knowledge Engine Demo

Turn biomedical documents into knowledge graphs, GraphRAG context, and source-traceable AI evidence.

Extraction Models

Choose biomedical NER and relation extraction settings.

GLiNER detects many biomedical entity types with configurable labels.

Enhanced hybrid combines biomedical patterns, sentence evidence, and ontology validation.

Ontologies

Select ontology sources for concept linking and surgical knowledge grounding. UMLS and SNOMED CT are active today; the other surgery ontologies are included as local-ready slots for the next loaders.

Input Sources

Select one or more places your documents come from. Add as many sources as needed.

No sources added. Paste text or upload files below.

Document Content

Use direct upload, file sources, folder sources, or pasted text.

No files selected. Paste text below or choose files.
