⚙️ Installation & Setup

Prerequisites

  • Python 3.8 or higher
  • Groq API key
  • Git

1️⃣ Clone the Repository

git clone https://github.com/danieladdisonorg/AI-Lawyer---RAG-with-DeepSeek-R1.git
cd AI-Lawyer---RAG-with-DeepSeek-R1

2️⃣ Set Up Virtual Environment

On macOS/Linux:

python -m venv venv
source venv/bin/activate

On Windows:

python -m venv venv
venv\Scripts\activate

3️⃣ Install Dependencies

pip install -r requirements.txt

4️⃣ Configure Environment Variables

Create a .env file in the project root:

echo "GROQ_API_KEY=your_groq_api_key_here" > .env

Or set it as an environment variable:

export GROQ_API_KEY="your_groq_api_key_here"

🚀 Usage

Running Locally

  1. Start the application:
streamlit run frontend.py

  1. Open your browser and navigate to http://localhost:8501

  2. Upload a legal document (PDF format)

  3. Ask questions about the document using natural language

  4. Download reports generated by the AI analysis

Example Queries

  • "What are the key terms and conditions in this contract?"
  • "Summarize the main legal obligations for each party"
  • "What are the potential risks mentioned in this document?"
  • "Explain the termination clauses in simple terms"

📜 How It Works

1. Document Processing

  • Upload: User uploads PDF legal documents
  • Extraction: Text is extracted using pdfplumber
  • Chunking: Documents are split into manageable sections

2. Vector Database Creation

  • Embedding: Text chunks are converted to vector embeddings
  • Indexing: FAISS creates searchable vector index
  • Storage: Vectors are stored for efficient retrieval

3. Query Processing

  • User Input: Legal questions are received via Streamlit interface
  • Retrieval: Relevant document sections are found using vector similarity
  • Context: Retrieved information provides context for AI response

4. AI Response Generation

  • DeepSeek R1: Advanced reasoning model processes query and context
  • Groq API: High-speed inference for real-time responses
  • Structured Output: Responses are formatted for legal clarity

5. Report Generation

  • Analysis: AI generates comprehensive document analysis
  • Formatting: Results are structured in professional format
  • Download: Users can download PDF reports

🔑 API Configuration

Groq API Setup

  1. Get API Key: Visit Groq Console and create an account
  2. Generate Key: Create a new API key in your dashboard
  3. Configure: Add the key to your environment variables or .env file
