 # 📰 QuickFactChecker – Fake News Detection
 
 ## 📌 Project Overview
-QuickFactChecker is a machine learning–based web app that helps detect whether a news article is **real** or **fake**.  
-It uses different models (e.g., Naive Bayes, LSTM) trained on the **LIAR dataset** to evaluate credibility and assist users in identifying potentially misleading information.

 ## ✨ Features
-- ✅ Fake news classification using ML models (Naive Bayes, LSTM).  
-- ✅ Interactive web app built with **Flask** and **HTML templates**.  
-- ✅ Preprocessed dataset included (`train.tsv`, `test.tsv`, `valid.tsv`).  
-- ✅ Notebooks for **data analysis & experimentation** (`liar-data-analysis.ipynb`, `dataset.ipynb`).  
-- ✅ Easy setup with `requirements.txt`.
