Grok Voice Agents with RAG

Build intelligent voice agents that can answer questions from your documents, manuals, FAQs, and knowledge bases.

What is RAG?

RAG (Retrieval-Augmented Generation) allows your voice agent to search through your uploaded documents and use that information to answer caller questions accurately. Instead of making up answers, the AI references your actual content.

Example: Upload your product catalog, and callers can ask "How much does the Pro plan cost?" - the agent will find and quote the exact price from your documents.
