This project is an Internship Major Project focused on developing a simple AI-based chatbot using Python and Flask.
The chatbot provides predefined responses to user queries through a web-based chat interface. The project demonstrates foundational concepts of backend web development, RESTful APIs, and basic conversational logic.
This project is developed strictly for learning, academic, and internship demonstration purposes, not for production deployment.
- To understand the fundamentals of chatbot development
- To learn the Flask framework for backend application development
- To implement client-server communication using HTTP requests
- To design a simple and interactive chat-based web interface
- To understand request–response flow in web applications
The AI-based chatbot application consists of:
- A Flask backend server that handles incoming user messages
- A predefined response system implemented using Python logic and dictionaries
- A REST API endpoint (
/chat) that accepts user messages and returns responses - A simple frontend built using HTML, CSS, and JavaScript
- Real-time interaction between frontend and backend using AJAX / Fetch API
When a user types a message:
- The message is sent to the Flask server
- The server processes the input
- A predefined response is selected
- The response is returned and displayed in the chat interface
Intent MatchingThe bot is pre-programmed with high-value answers. Below is a representation of how the developer-defined responses are structured:
| User Query (Inbuilt Intent) | Bot Knowledge (Programmed Response) |
|---|---|
| What is Python? | Explains Python as a popular high-level programming language known for its simplicity and versatility. |
| What is AI? | Defines Artificial Intelligence as machines designed to perform tasks that typically require human intelligence. |
| I am sad | Provides empathetic emotional support, reminding the user that they are strong and that tough times are temporary. |
| Tell me a joke | Returns a lighthearted, pre-selected joke (e.g., “Atoms” or “Skeleton” joke) to engage the user. |
- Python – Core programming language
- Flask – Backend web framework
- HTML – Structure of the web interface
- CSS – Styling of the chatbot UI
- JavaScript – Client-side logic and API calls
- JSON – Data exchange format
- Git & GitHub – Version control and project hosting
- The frontend sends user input to the Flask backend using HTTP POST requests
- Flask processes the message using predefined logic
- A matching response is selected
- The response is sent back to the frontend
- The chat interface updates dynamically
- This project was developed as part of an AI / Python Internship Major Project
- It focuses on concept clarity and practical implementation
- The project demonstrates basic AI concepts without using advanced NLP models
This chatbot uses simple rule-based logic and does not use advanced AI or NLP models. It is intended only for educational and internship learning purposes.
- Understanding of Flask-based backend development
- Knowledge of REST API creation and usage
- Experience in frontend–backend integration
- Basic understanding of chatbot logic and flow
- Improved confidence in Python web applications
- Integration of NLP libraries (NLTK, spaCy)
- Database support for conversation history
- Machine learning-based response generation
- User authentication and session management
