AI Sales Agent: Multilingual Lead Qualification

A conversational sales assistant that talks to leads in English, Hindi, or Hinglish, answers their questions, handles objections, books site visits, and passes the conversation to a human when needed.
Demo: a real-estate agent ("Priya" from the fictional Northstar Homes, Sector 79, Gurugram). The same agent can be adapted to clinics, coaching institutes, e-commerce, or any business that gets repeated enquiries.

The problem

Leads message at all hours, and slow or inconsistent replies lose sales. Many Indian customers also prefer to chat in Hindi or Hinglish, which most chatbots handle badly.

What it does

Chats naturally in English, Hindi, and Hinglish. It replies in the language the lead uses.
Qualifies leads. It asks the right questions, such as whether the buyer is looking for themselves or as an investment.
Answers from project details. Configurations, pricing, and location are given consistently.
Handles objections. It responds to hesitation about price or timing instead of ending the chat.
Books site visits. Interested leads move toward a confirmed appointment.
Escalates to a human. Complex or sensitive conversations are handed over.
Remembers the conversation. Session-based memory keeps replies in context.
Streams replies live. Answers appear word by word, like a real chat.
Tested. Checked against 8 structured test scenarios.

Where this fits

Real estate lead qualification
Clinic and coaching-institute enquiry handling
E-commerce pre-sales support
WhatsApp-style first-response bots for small businesses
