We’re excited to launch the EXCALIBUR project and welcome you to our community of researchers, developers, and stakeholders committed to advancing trustworthy and responsible artificial intelligence.

What is EXCALIBUR?

EXCALIBUR is an EU-funded research initiative that bridges regulatory principles with technical innovation. Our mission is to democratize access to tools and methodologies for building explainable, fair, and accountable AI systems-making trustworthy AI accessible to everyone.

Our Approach

Our project is built on three interconnected pillars:

1. Regulatory-to-Technical Mapping
We translate international AI ethics frameworks and regulatory requirements into concrete technical specifications. Learn more about our objectives and methodology.

2. LLM-powered Explainability & Fairness
We develop advanced, model-agnostic tools that generate human-readable explanations and fairness assessments. Explore our core framework and components.

3. Open Tools & Stakeholder Validation
We’re building an open-source platform with intuitive visualizations and an iterative design process involving real users. Check out our software and tools in development.

Our Journey

The project combines rigorous in-lab experimentation with real-world case studies in the wearables domain, where trust, clarity, and fairness are especially critical. We follow a citizen-science approach to ensure our tools meet authentic user needs.

Get Involved

Whether you’re a researcher, developer, or stakeholder interested in trustworthy AI, there are many ways to engage with us:


EXCALIBUR is implemented under the Hellenic Foundation for Research and Innovation (ELIDEK) through the National Recovery and Resilience Plan “Greece 2.0”, funded by the European Union – NextGenerationEU.
