Understanding The Problem & Our Approach

The Challenge

The enterprise received 100K+ support tickets monthly with 45-minute average resolution time and 60% customer satisfaction due to generic automated responses.

Legacy Systems Scalability Issues Data Silos

Our Solution

We deployed an enterprise AI chatbot with multi-language NLP, knowledge base auto-learning, sentiment-aware routing, live agent handoff, and conversation analytics.

End-to-End Technical Workflow

Customer query intake, RAG knowledge retrieval, GPT-4 response generation, confidence-based escalation, and CRM ticket creation.

01

Query Intake

Customer message received; language detected and conversation history appended to context window.

Input: Customer Message
Output: Contextualised Query
02

Knowledge Retrieval

LangChain embeds query and retrieves top-5 relevant knowledge base chunks from Pinecone vector store.

Input: Query Embedding
Output: Relevant KB Chunks
03

Response Generation

GPT-4 generates a grounded response using retrieved KB context with citation references and confidence score.

Input: Query + KB Context
Output: AI Response + Confidence
04

Escalation & Ticketing

Low-confidence or negative-sentiment responses trigger human agent handoff with conversation history pre-loaded in Zendesk.

Input: Low Confidence / Negative
Output: Zendesk Ticket + Agent

RAG Knowledge Pipeline

Knowledge base articles chunked, embedded with text-embedding-ada-002, and indexed in Pinecone for semantic retrieval at 10ms.

Hallucination Guard

Response grounding check compares GPT-4 output against retrieved chunks using NLI model, flagging unsupported claims for review.

Proactive Intent Routing

Intent classifier pre-routes known high-volume topics (password reset, order status) to deterministic handlers before invoking LLM.
