Case study
AI video sales agent
An AI video sales agent that answers website visitors on live calls, with an end-to-end RAG pipeline and real-time video on LiveKit.
The problem
What needed solving
Website visitors with early questions had to wait for a sales rep. The business wanted them to get answers straight away on a live video call with an AI agent.
What I did
How I approached it
- Built the RAG pipeline end to end, including the chunking strategy and embeddings, so the agent answers from the company's own product content.
- Built the real-time video call experience on LiveKit.
- Made the agent show relevant product images and videos on screen as the conversation moves.
