OntoBoom is the AI-assisted IDE for ontology modeling.

Design ontologies visually, validate them in real-time, and export production-ready RDF + SHACL for your knowledge graphs and AI systems.

“Ontology engineering is becoming mainstream because AI systems need structure, not just embeddings.”

Graph RAG systems need explicit relationships to reason over.

AI agents need semantic models to understand domain constraints.

Knowledge graphs need well-defined schemas to scale reliably.

Ontology tooling hasn't kept up with modern development.

Academic tools with steep learning curves and unintuitive interfaces

Manual, error-prone workflows that slow down iteration

Validation that happens too late, after the damage is done

Disconnected from modern AI workflows and development practices

Ontology modeling shouldn't feel like configuring research software from 15 years ago.

A modern modeling environment — built for builders.

OntoBoom isn't a graph database. It's not a marketplace. It's the IDE where ontologies are designed visually and iteratively, with AI-powered assistance, then exported to your production systems.

Key Features

Visual Ontology Canvas

Drag-and-drop classes, properties, and relationships. See your ontology structure at a glance with an intuitive graph editor.

AI Copilot

Accelerate your workflow with intelligent suggestions, automatic error detection, and instant fixes. Build ontologies 10x faster.

Validation Built In

Real-time validation catches issues as you design. No more discovering broken ontologies after deployment.

JSON-First Workflow

Work with a clean JSON representation that's easy to version control, diff, and integrate with your existing tools.

Schema Import

Import from DDL/SQL, CSV, JSON, XML Schema, Turtle, JSON-LD, and RDF/XML. Convert existing schemas instantly.

Multi-Format Export

Export to Turtle, JSON-LD, RDF/XML, OWL, SHACL shapes, and Cypher for triple stores and graph databases.

REST API

Programmatic access to your ontologies. Generate API tokens for external apps, pipelines, and automated workflows.

MCP Protocol

Connect Claude Desktop and AI assistants directly to your ontologies via Model Context Protocol.

Use Cases

Graph RAG Grounding

Build the semantic schema that powers retrieval-augmented generation. Define entities and relationships that give your LLM structured context to reason over.

Knowledge Graph Design

Design enterprise knowledge graphs with proper class hierarchies, property constraints, and data validation rules before loading your first triple.

AI Governance & Constraints

Encode business rules and domain constraints that AI systems must respect. Turn implicit knowledge into explicit, enforceable schemas.

Domain Modeling for Agents

Give AI agents a formal understanding of your domain. Model concepts, relationships, and constraints that help agents make better decisions.
