From Zero to ChatGPT: The Complete Journey of Building Your Own AI Chatbot (VOL-1)

Learn Conversational AI, NLP, Large Language Models, and Build Intelligent AI Chatbots from Scratch

Author: Anshuman Mishra

Artificial Intelligence has fundamentally transformed the way humans interact with technology. From simple rule-based virtual assistants to advanced conversational systems powered by Large Language Models (LLMs), chatbots have evolved into intelligent digital assistants capable of understanding language, answering questions, generating content, solving problems, and assisting millions of users across industries.

Today, conversational AI powers customer support, healthcare, education, finance, e-commerce, software development, research, productivity tools, and countless business applications. Technologies like ChatGPT have demonstrated that modern AI systems can engage in natural conversations, assist with complex reasoning, generate high-quality content, write code, summarize information, and support decision-making in ways that were unimaginable only a few years ago.

From Zero to ChatGPT: The Complete Journey of Building Your Own AI Chatbot (VOL-1) is a practical, project-oriented, and beginner-friendly guide that teaches readers how modern conversational AI works and how to build intelligent chatbots from the ground up using Python, Natural Language Processing (NLP), Deep Learning, and Large Language Models.

Whether you are a student beginning your AI journey or a software developer interested in building intelligent conversational applications, this book provides a structured learning path from the history of chatbots to integrating modern LLM-powered assistants.
