PDF Quizzer (Flask)

A simple Flask web app where users can upload a PDF or enter a topic name. The app summarizes the content and generates a small multiple-choice quiz. Users can answer and get instant grading.

Features

• Upload PDF and extract text with PyPDF2
• Enter a topic (uses Wikipedia content)
• Frequency-based extractive summarization (NLTK)
• Auto-generated MCQ quiz and instant grading
• Minimal modern UI

Setup

1. Create a virtual environment (Windows PowerShell):

python -m venv .venv
.\.venv\Scripts\Activate.ps1

2. Install dependencies:

pip install -r requirements.txt

3. Run the app:

$env:FLASK_SECRET_KEY = "change-me"
python app.py

Open http://localhost:5000 in your browser.

Notes

• Quiz generation is heuristic; results depend on input quality.
• Wikipedia scraping has rate limits; avoid heavy usage.
• If NLTK downloads fail on first run, re-run the app while online.
