Introduction

Chatbots and AI-based conversational systems are intelligent solutions designed to automate customer interactions across websites, mobile apps, and messaging platforms. These systems use Natural Language Processing (NLP), Machine Learning (ML), and automation frameworks to understand user queries and provide accurate responses. They help organizations improve customer experience, reduce response time, and enable 24/7 support across digital channels.
