1.Client Background

A growing fintech startup offering digital lending and investment services was facing an overwhelming volume of customer support tickets. With a lean support team, response times exceeded 36 hours during peak periods. Most queries were repetitive—about KYC, EMI due dates, transaction failures, or how to use the app.

They wanted to deploy an AI chatbot to automate at least 60% of Tier-1 queries without sounding robotic or compromising on accuracy.

2. The Challenge

The chatbot needed to work across multiple platforms (website, mobile app, WhatsApp), understand user intent in English and Hindi, and access real-time customer data such as loan status or investment portfolio. It also had to escalate to live agents gracefully when needed.

Additionally, because the fintech firm was regulated under RBI guidelines, any system accessing financial data had to follow strict security, logging, and audit controls.

3. Our Approach

Warke Technologies designed a modular NLP-driven architecture with financial domain understanding. We conducted conversation flow workshops with the client’s support staff and manually labeled historical chat data to train the intent engine. The system was built with fallback layers to ensure no query went unresolved.

We prioritized empathy in language and added mini-tutorials (text + gifs) for app-related questions, reducing dependency on helpdesk tickets.

4. Solution Delivered

We implemented a scalable, AI-Powered Omnichannel Chatbot with secure data access, including:

• Natural Language Understanding (NLU) Engine:
• Trained on 200+ financial intents (e.g., “How do I check my EMI?”, “My payment failed”)
• Dual-language support with Hinglish handling and regional syntax tolerance
• Platform Integrations:
• Embedded in web app, mobile app (React Native), and WhatsApp
• Omnichannel session continuity — customers could switch platforms without restarting
• Real-Time Data Integration:
• Secure connection to user account info (loan due date, investment status, profile KYC)
• Dynamic answers with context: “Your next EMI of ₹3,290 is due on July 10”
• Smart Escalation Engine:
• Escalate to human agent if intent is unknown, emotion detected (anger, urgency), or conversation exceeds 3 turns
• Ticket creation with chat history for smooth handoff
• Admin Dashboard:
• Query volume trends, unresolved intent log, training data curation
• Conversation quality scoring and NPS feedback capture

5. Technologies Used
