📖 Overview

AI FAQ Assistant is an intelligent chatbot that enables users to ask questions in natural language and receive accurate answers from a predefined FAQ knowledge base.

Unlike traditional FAQ pages that require users to manually search through long lists of questions, this chatbot automatically finds the best possible answer using multiple search strategies.

The application provides a clean, responsive, and user-friendly interface for a seamless question-answering experience.

---

🎯 Problem Statement

Traditional FAQ systems become difficult to use as the number of questions increases.

Users often experience:

• Searching through lengthy FAQ pages
• Difficulty finding relevant answers
• Different wording than stored questions
• Poor user experience

The AI FAQ Assistant solves these challenges by providing an intelligent conversational interface capable of understanding user intent and retrieving the most relevant answer.

---

💡 Solution

The chatbot processes each user query through multiple search techniques before selecting the most appropriate response.

Instead of relying on a single search method, it combines:

• ✅ Exact Matching
• ✅ Fuzzy Search
• ✅ Keyword Matching

This approach increases search accuracy while maintaining fast response times.
