In the RATIONAL project, one central challenge was front and center: the expertise of ChefLine employees existed predominantly in their heads, not in a database.

Our approach: all available sources, including recipes, operating manuals for different appliance generations, service handbooks, and videos, were systematically unlocked, cleaned, and consolidated into a unified knowledge base. The RAG system now makes this knowledge accessible through natural language queries.

The decisive effect: when experienced employees leave the company, their knowledge remains in the system and available.
