Enterprise RAG Platform + WhatsApp AI Assistant (1M+ Docs)

Knowledge-Graph RAG Engine & Multimodal WhatsApp Assistant

The client had a 1M+ document knowledge base that employees couldn't reliably search, with no way to trust an AI answer without checking its source. ScaleVexo built a hybrid RAG platform combining semantic search, keyword search, and knowledge-graph reasoning for accuracy on exact terms and multi-hop questions alike. Every answer carries a confidence score — low-confidence cases escalate to a human instead of the model guessing. The same knowledge layer powers a WhatsApp assistant supporting text and voice notes, with full admin visibility into documents, conversations, and escalations.
