What It Does

Your 24/7 AI Agent on WhatsApp

India has 500M+ WhatsApp users. Our AI chatbot puts you inside their most-used app — answering questions, capturing leads, booking appointments and sending reminders — automatically.

Unlike generic bots, our system uses RAG (Retrieval Augmented Generation) to give accurate answers from YOUR business data — product catalogue, FAQs, price list, policy documents.
