A Python-based prototype that processes PDF promotional materials for spellchecking, grammar checks, and basic formatting consistency using Google's Gemini API for multimodal (text + image) analysis.

Features

• Upload PDF promotional materials
• Analyze each page for spelling/grammar errors and formatting issues
• Review flagged issues in a web UI
• Accept or reject suggestions
• Generate a summary report

Setup

Prerequisites

• Python 3.8 or higher
• Google Gemini API key

Installation

1. Clone this repository:

   git clone <repository-url>
   cd pdf-promo-checker
   

2. Install dependencies:

   pip install -r requirements.txt
   

3. Download Poppler binaries for Windows:

   • Download from https://github.com/oschwartz10612/poppler-windows/releases/
   • Extract the contents to the bin directory in the project
   • The application will automatically find the binaries in the correct location
   • No need to add to PATH as the application will use the local binaries

   Note: The application is configured to use Poppler binaries from the bin/poppler-24.08.0/Library/bin directory. If you download a different version, you may need to update the path in pdf_processor.py.

4. Create a .env file in the project root with your Google Gemini API key:

   GOOGLE_API_KEY=your_api_key_here
   SECRET_KEY=your_secret_key_here
   

Running the Application

1. Start the Flask application:

   python app.py
   

2. Open your browser and navigate to http://localhost:5000

Usage

1. Upload a PDF file using the web interface
2. Wait for the analysis to complete
3. Review the flagged issues
4. Accept or reject suggestions
5. Generate a summary report
