Oxford Semantic Technologies launches RDFox Mantix

Oxford Semantic Technologies launches RDFox Mantix to speed up the development of trusted AI built on human expertise

OXFORD, UK – 29 September 2026 - Oxford Semantic Technologies today announced the launch of RDFox Mantix, a visual collaborative companion to RDFox, its high-performance knowledge graph and reasoning engine.  

Designed to make RDFox’s powerful capabilities accessible for more people to use, Mantix helps domain experts, technical teams and semantic specialists work together to build knowledge-based AI systems.  

Generative AI has made it easier than ever to interact with information using natural language, but many business applications require the answers AI generates to be grounded in an organisation’s own data, definitions, rules and expertise.  

Knowledge-based AI does just that, allowing companies to get all the benefits of LLMs, but with answers that are reliable, controllable and auditable.  

A shared visual environment for direct collaboration

Building knowledge-based applications requires different kinds of expertise – from domain knowledge and technical skills to specialist semantic expertise. Bringing those skills together effectively can take time and create bottlenecks.

RDFox Mantix bridges this gap by providing a shared visual environment where domain experts, technical teams and semantic specialists can now collaborate directly to build knowledge graphs much more quickly.

A generative-AI interface also translates natural language questions into queries RDFox can process. The LLM helps express the question; the answer comes from RDFox, grounded in the organisation's data, semantics and explicitly captured business logic.

Key features include:

• Visual Model:  Intuitive visual tools allow users to explore and develop knowledge models, map data and create rules without needing to code.

• Collaborative Environment: Domain experts, technical teams and semantic specialists can contribute their expertise more directly.  

• Generative AI assisted interaction: Use natural language to ask questions that are translated into queries RDFox can answer.

Peter Crocker, CEO of Oxford Semantic Technologies said:  

“Organisations have enormous amounts of valuable knowledge - not just in their data and systems, but in the expertise of their people. RDFox already gives organisations a powerful way to put that knowledge to work through AI. With Mantix, we're making those capabilities easier for more people to access and use, helping domain experts, technical teams and semantic specialists work together more effectively and accelerate the path from idea to business value."

RDFox Mantix is available immediately as an add-on companion for new and existing RDFox customers.
