Legal Lens

An AI-powered tool for automatic contract analysis, extracting key clauses, highlighting risks, and streamlining legal document review.

🚀 Features

• Extracts key legal clauses (salaries, penalties, fees, liability, dispute resolution, etc.).
• Uses OpenAI GPT-4 to identify risky clauses.
• Highlights text physically in the PDF using an orange marker.
• Processes PDFs page by page to avoid API limits.

📌 Installation

1. Clone this repository

git clone https://github.com/juliuspleunes4/legallens.git
cd legallens

2. Install dependencies

pip install -r requirements.txt

3. Set up environment variables

Create a .env file in the root directory with the following text:

OPENAI_API_KEY=YOUR_API_KEY_HERE

📄 Usage

1. Place the PDF file you want to analyze in the root directory.
2. Name it input.pdf.
3. Run the script:

   python main.py

4. The output PDF with highlighted clauses will be saved as legallens.pdf.

🛠️ Troubleshooting

⚠️ OpenAI Rate Limit Error

• The script will automatically switch to gpt-3.5-turbo if gpt-4 exceeds its token limit.
• If API calls still fail, try reducing the PDF size or splitting it into smaller sections.

⚠️ Incorrect Highlighting (single letters instead of full sentences)

• Ensure your PDF contains selectable text rather than scanned images.

⚠️ Missing Dependencies

• Run pip install -r requirements.txt again to ensure all necessary packages are installed.
