How it Works ?

1. Setup and Configuration:

• Streamlit Page Configuration: The page is configured with a custom theme including background, text, and primary colors.
• Groq API Key: The application retrieves the Groq API key from the environment variable GROQ_API_KEY.

2. Database Initialization:

• SQLite Connection: The application connects to an SQLite database (user_profiles.db).
• Tables Creation: If not already present, it creates two tables: users for user authentication data and user_profiles for storing user queries and AI-generated responses.

3. Session State Initialization:

• Session Variables: It initializes session state variables to keep track of the user's login status, user ID, and username.

4. User Authentication:

• Signup: Users can create a new account by providing a username, email, and password. The password is hashed using SHA-256 before being stored.
• Login: Existing users can log in using their email and password. Upon successful login, session state variables are updated with the user's information.

5. AI Model Initialization:

• Chat Models: Two AI models are initialized using the Groq API:
• chat for legal advice with the llama3-70b-8192 model.
• llm for document generation with the llama3-8b-8192 model.

6. Prompt Templates:

• Legal Advice Prompt: A prompt template for legal advice is defined.
• Document Generation Prompt: A prompt template for document generation is defined.

7. User Interface:

• Main Interface: Once logged in, users are welcomed and presented with a text area to input their queries or document content.
• Option Selection: Users can select either "Get Legal Advice" or "Generate Document" from a dropdown menu.

8. Processing User Input:

• Legal Advice: Upon clicking "Give Advice," the user input is processed through the legal advice model. The generated response is displayed and saved in the database.
• Document Generation: Upon clicking "Generate Document," the user input is processed through the document generation model. The generated document content is displayed and saved in the database.

9. Display User History:

• Query and Response History: The application retrieves and displays the user's previous queries and responses from the database.

10. Closing the Database Connection:

• Connection Closure: The database connection is closed at the end of the script to ensure proper resource management.
