Dual-Mode AI Chatbot for Karji Store

Client Overview

Karji Store is an innovative eCommerce platform offering a wide range of products across multiple categories. To elevate customer experience and streamline operations, the company envisioned an AI-driven chatbot capable of both sales assistance and customer support automation.

The goal was to create a conversational system that not only recommends the right products to increase conversions but also resolves customer queries quickly and accurately — functioning as an always-available, intelligent digital assistant.

Problem Statement

With increasing catalog size and growing customer interactions, Karji Store faced two key challenges:

  • Product Discovery & Conversion Gaps
    • Customers often left without finding the right product due to information overload.
    • The lack of personalized recommendations reduced conversion rates.
  • Customer Support Overload
    • A large volume of repetitive queries — delivery, returns, policies, warranty — consumed the support team’s time.
    • Inconsistent response quality and slow resolution affected customer satisfaction.

Karji Store wanted a unified AI chatbot that could act both as a Sales Advisor and Customer Support Executive, with dynamic context awareness, product intelligence, and policy understanding.

Our Approach

Megh Technologies partnered with Karji Store to develop a Dual-Mode AI Chatbot — an advanced conversational system powered by Retrieval-Augmented Generation (RAG), custom embeddings, and vector-based search.

We designed the solution to operate in two intelligent modes:

  • Recommendation Engine (Sales AI) – Engages users, understands their intent, recommends products, compares items, and assists in purchase flow.
  • Support Engine (Support AI) – Handles all customer support queries including orders, policies, returns, and troubleshooting.

The chatbot was built as a fully embeddable widget, seamlessly integrated into the Karji Store website, ensuring consistency across desktop and mobile experiences.

Results & Impact

  • Sales Growth: Personalized product recommendations increased user engagement and boosted conversions.
  • Reduced Support Load: Over 70% of repetitive queries handled autonomously by Support AI.
  • 24/7 Availability: Customers receive consistent, instant answers at all times.
  • Improved User Experience: Unified conversational interface for both sales and support.
  • Easy Maintenance: Admins can easily manage, update, and re-train data without developer dependency.
  • Scalable Architecture: Widget-based design enables integration across future Karji Store expansions.
