With millions of questions each month, any deflection to a LLM-powered chatbot would significantly improve their top and bottom line. Traditional question-answer engines were ineffective for millions of SKUs. In addition, product knowledge was spread across product specs, user manuals, online blogs, images, and videos, making it difficult to manage and retrieve information efficiently.
