Leyli
Build Knowledge Once.
Power Every AI.
Leyli transforms complex documents and enterprise information into structured, ontology-grounded knowledge that people, AI systems, and intelligent agents can inspect, reuse, and trust.
Watch Leyli in action.
A short public beta walkthrough of Leyli's knowledge engine, using biomedical documents as the first proof of source-traceable, graph-based, AI-ready knowledge.
Most AI systems retrieve information.
Leyli builds knowledge.
Leyli helps teams move beyond document search and isolated GraphRAG workflows by creating trusted knowledge that can be reused across people, products, LLMs, and AI agents.
Knowledge, not documents
Most AI systems retrieve chunks of text. Leyli transforms documents into structured, connected knowledge that can be explored, inspected, and reused across applications.
Explainable by design
Every entity, relation, and generated answer remains connected to its original source evidence. Users can inspect exactly where knowledge comes from instead of trusting a black box.
Ontology-aware intelligence
Leyli links extracted knowledge to domain ontologies such as UMLS and SNOMED CT. This creates consistent concepts, semantic understanding, and richer context across enterprise data.
Infrastructure for AI
Leyli is not another chatbot. It is the knowledge infrastructure that enables GraphRAG systems, enterprise AI applications, and agentic AI workflows.
Trustworthy AI starts with trustworthy knowledge.
A simple path from information to knowledge.
Leyli connects source material, domain meaning, graph structure, and delivery formats in one explainable pipeline.
The homepage shows the short version. The Technology page explains the complete workflow and architecture.
One Knowledge Engine.
Unlimited domains.
Leyli transforms domain knowledge into explainable, AI-ready systems. The domain changes; the engine stays reusable.

Leyli is currently in Public Beta. We are inviting a limited number of researchers, AI teams, healthcare innovators, and enterprise organizations to explore the platform, provide feedback, and help shape its future.
Built from Hamburg for trustworthy AI.
Leyli was created to solve a fundamental problem: valuable organizational knowledge is often trapped inside documents, disconnected systems, and domain-specific language. Our mission is to make expert knowledge computable, explainable, and reusable for people and AI. We are building knowledge infrastructure that helps AI systems move beyond text retrieval toward structured, evidence-backed understanding.
