Example of CRAWLGPT in action!

🔧 Requirements

• Python >= 3.8
• Operating System: OS Independent
• Required packages are handled by the setup script.

🚀 Quick Start

1. Clone the Repository:

   cd CRAWLGPT
   

2. Run the Setup Script:

   python -m setup_env
   

   This script installs dependencies, creates a virtual environment, and prepares the project.

3. Update Your Environment Variables:

   • Create or modify the .env file.
   • Add your Groq API key and Ollama API key. Learn how to get API keys.

   GROQ_API_KEY=your_groq_api_key_here
   OLLAMA_API_TOKEN=your_ollama_api_key_here
   

4. Activate the Virtual Environment:

   source .venv/bin/activate  # On Unix/macOS
   .venv\Scripts\activate  # On Windows
   

5. Run the Application:

   python -m streamlit run src/crawlgpt/ui/chat_app.py
