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.

- 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
