Generative AI is changing how people interact with the internet. Users now expect conversational experiences instead of structured filters. At Scout24, we built HeyImmo to meet this shift.
This talk covers HeyImmo, an AI-driven conversational assistant that replaces filter-based interactions across our platform. Beyond search, it helps users estimate property value, find agents, and explore financial options – all through natural language. We’ll discuss our technical stack (OpenAI model combination, MCP-based modular architecture), quality measurement framework (three-dimensional evaluation using Golden Answer datasets), and organizational setup (distributed development across product teams with central AI platform team).
