The Problem

Knowledge graph tools weren't made for you

Traditional ontology editors like Protégé, TopBraid, or enterprise tools like Collibra assume you already speak the language of semantic web standards, RDF triples, and Description Logic. They're powerful, but they're built for specialists.

Steep learning curve

Weeks of training before you can create anything useful

Overhead everywhere

Accounts, installations, configurations, licenses

Expert-only territory

Domain experts can't contribute without IT help

The Solution

Modeling should feel like thinking

Termboard strips away the complexity. You draw boxes, connect them with lines, and add descriptions. That's it. Behind the scenes, you're building standards-compliant semantic models.

Create terms

Click to add concepts. Give them names. Add descriptions in plain language.

Draw connections

Drag between terms to create relationships. Label how they relate.

Share & export

Export to Excel, JSON-LD, OWL, PowerPoint, PDF, or images.

Simple Interface, Serious Capabilities

Power when you need it, hidden when you don't

Automatic Quality Checks

14 built-in validations catch common mistakes: duplicate names, circular hierarchies, missing descriptions. No expertise needed to build quality models.

Your Data Stays Yours

100% browser-based. Nothing is uploaded. Nothing is tracked. Your models live in your browser or on files you control.
