The Challenge

A Spanish automation agency needed a bilingual (English/Spanish) AI assistant that could answer complex technical questions from their internal SharePoint knowledge base and external documentation — without hallucinations.

Our Solution

  • Built a Copilot Studio agent with custom topic flows and language detection routing
  • Integrated Azure AI Search with hybrid vector + keyword retrieval for accurate document grounding
  • Connected SharePoint as a live knowledge source via Power Automate custom connectors
  • Implemented GPT-4 embeddings for semantic search and GPT-4 completion for response generation
  • Added external REST API integrations for real-time data from third-party systems
