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.

  • Instant replies to customer queries 24/7
  • Hindi + English + Hinglish understanding
  • Lead capture — name, number, requirement
  • Appointment / slot booking automation
  • Order status, tracking, delivery updates
  • Product catalogue browsing via chat
  • Payment reminders and follow-up sequences
  • Escalate complex queries to human agent
