Ontologies give agentic systems the structure they need to reason and act reliably
By defining how concepts connect, ontologies transform unstructured data into machine-readable knowledge.
Agents can then interpret, reason, and explain their actions with greater accuracy and transparency.
Streamlined Data Integration
Organize and manage your data more effectively, facilitating collaboration and decision-making across your organization.
Improve data integration and interoperability across different systems and departments, enabling smoother communication and collaboration among various parts of your organization.


Empowering Automation and AI with Ontologies
Ontologies lay the groundwork for smart systems like AI and automation.
By organizing data and establishing connections, they enable algorithms to reason and automate tasks, leading to smoother operations and increased efficiency.
Build your ontology from your data
Effortlessly create your first ontology by automatically integrating relevant concepts and relationships from diverse unstructured data sources, such as csv, txt and pdf.
Our system ensures the integrity and coherence of your ontology by carefully vetting suggested additions, filtering out noise, and prioritizing relevance.

How it works?
Here's what we offer in four steps:
1. Upload data
Simply upload your datasets.

2. Kickstart ontology & Analyze
Add a few important concepts related to your company and identify areas for ontology enrichment.

3. Enrich
Review and approve suggested enrichments, or customize them to better fit your needs.

4. Apply
Apply the enriched ontology to your projects, gaining deeper insights and improving data understanding.
