Chatbots are rapidly transforming how users interact with technology—across websites, apps, customer support systems, and even voice assistants. This comprehensive self-paced course on Chatbot Architecture is designed to teach you how to design, build, and deploy conversational AI systems that are context-aware, scalable, and user-centric.
 
Whether you're creating a simple FAQ bot or a multi-turn LLM-powered assistant, chatbot development today involves more than just scripting responses. It requires thoughtful architecture, including natural language understanding (NLU), dialogue management, context persistence, integration layers, and AI services like LLMs, RAG, and memory systems.
 
In this course, you'll explore the architectural components of modern chatbots, including intent classification, entity extraction, memory stores, vector-based retrieval, tool calling, and human handoff mechanisms. You’ll build bots using tools like Rasa, Dialogflow, LangChain, OpenAI GPT, FastAPI, and Streamlit.
 
What is Chatbot Architecture?
 
Chatbot architecture refers to the underlying design, modules, and systems that power intelligent, dynamic conversational agents. This includes message pipelines, NLP processing, API integrations, memory management, fallback strategies, and deployment layers.
 
This course helps you understand and implement these components to build real-world bots that go beyond static responses—bots that remember, search, reason, and respond intelligently.
 
How to Use This Course
 
  1. Start with Core Concepts – Understand how chatbot workflows and pipelines operate.
  2. Build from Scratch – Create bots with and without LLMs using open-source tools and cloud APIs.
  3. Apply Conversation Design – Learn how UX impacts architecture.
  4. Integrate External Tools – Connect your bot to databases, APIs, search, and memory layers.
  5. Capstone Projects – Create your own intelligent assistant for specific domains (e.g., education, finance, internal support).

Interview Questions Back to Top
1. What are the core components of chatbot architecture?
NLU (intent & entity extraction), Dialogue Management (flow control), NLG (response generation), integrations (APIs), and front-end interface.
 
2. What is the role of a Dialogue Manager?
It handles the flow of conversation by maintaining state, managing context, and deciding what the bot should do next.
 
3. How does RAG improve chatbot capabilities?
RAG allows the chatbot to retrieve relevant documents or facts from a vector store and use them as grounding for generating accurate responses.
 
4. What is intent classification and how is it done?
Intent classification identifies what the user wants. It’s typically done using ML classifiers trained on labeled phrases or transformer-based models.
 
5. How do bots maintain context across conversations?
Using memory mechanisms like slot-filling, session state, vector memory, or summarization-based memory.
 
6. What is the difference between rule-based and AI-based chatbots?
Rule-based bots follow predefined paths; AI-based bots use machine learning or LLMs to respond flexibly based on understanding.
 
7. What is fallback handling in chatbots?
A strategy to gracefully handle unclear inputs or errors—such as asking for clarification, rephrasing, or offering default options.
 
8. What are tools in LangChain agents?
Tools are external functions or APIs that the LLM can use to perform actions like search, math, or API calls based on user input.
 
9. How can you evaluate chatbot performance?
Using metrics like conversation success rate, fallback rate, user retention, satisfaction scores, and intent recognition accuracy.
 
10. How do you deploy chatbots to production?
Deploy using APIs (FastAPI), frontends (Streamlit, React), connect to platforms (Slack, WhatsApp), and host using cloud platforms with monitoring.
