ONTOLOGY BUILDER

Build the Structural
Backbone of AI

Design ontologies, taxonomies, and knowledge graphs visually. Export to YAML or JSON and feed them directly into LLM agent pipelines, RAG systems, and domain classifiers.

Four ways to work

Every path leads to a
precise ontology

Import

Upload Ontology

Import an existing YAML or JSON ontology and watch it transform into an interactive knowledge graph on the visual canvas.

Discover

Learn from Documents

Upload a batch of real documents — the AI identifies recurring entities, maps their structure, and assembles an ontology automatically.

Design

Build Visually

Create ontologies of any complexity with an intuitive drag-and-drop canvas. Connect nodes, define edge types, and add constraints — no code.

Run & Iterate

Fire a prompt through your ontology, trace every routing decision in detail, and measure performance. Runs are saved — compare iterations and improve.

Capabilities

Everything you need to design
precision ontologies

Visual Graph Editor

Drag-and-drop canvas powered by React Flow. Connect nodes, define edges, and see your ontology come alive in real time.

Taxonomy Management

Structure complex domains with classes, properties, values, dimensions, and constraints. Six node types, seven edge types.

YAML / JSON Export

Export your ontology as structured YAML or JSON — ready to plug into LangGraph agent pipelines, RAG systems, or LLM routers.

Multi-Domain Support

Hiring, finance, healthcare, legal, product — any domain. Tag ontologies, filter by domain, and manage them from a single dashboard.

Import & Parse

Upload existing YAML or JSON ontologies. Automatic node positioning, edge inference, and domain detection from file structure.

AI Pipeline Ready

Designed as the structural backbone for agent clusters. Router → Cluster agents → Combiner → Scorer. Your ontology drives every step.
