AI Chatbot for a city

// The problem

The city office was buried in repetitive citizen questions — opening hours, fees, waste, events — and foreigners could not navigate Czech-only information. Human capacity could not scale forever.

// The solution

We deployed a multilingual AI assistant that answers strictly from trusted sources: RAG over the city's official documents plus live queries against the city database. Answers are moderated and cited, so a citizen can verify the source. Production-hardened (Azure Key Vault, error alerting).

// Results
  • Multi-agent swarm engine — self-healing text-to-SQL, replies within 3 seconds
  • One of the first live civic chatbots in the Czech Republic
  • Multilingual — also helps foreigners and expats
  • Won a regional hackathon (Innovation Day)
