Start by verifying your email to access the AI-powered PDF assistant securely, enabling personalized usage tracking.

Follow these steps:

1. Input Email: Enter a valid email address in the designated field on the landing page, with format validation ensured.
2. Submit Email: Click the 'Submit Email' button to verify. Invalid formats trigger an alert.
3. Gain Access: Successful validation unlocks the main interface and AI-driven PDF tools.

Ensure a valid email format to proceed.

Step 2: Uploading Your PDF - Ready for Analysis

After accessing the app, upload your PDF document. The system supports various document types for comprehensive analysis.

Steps to upload:

1. Find the Upload Section: Look for the 'Drag and Drop' or 'Browse Files' option, choosing what suits you.
2. Choose Your PDF: Select the PDF from your device, ensuring it meets the size limit specified.
3. Process the File: The system converts the PDF into searchable text chunks. Larger files may take longer.

Check if the document’s text is selectable, as this affects the AI’s processing accuracy.

Step 3: Querying and Receiving Answers

With the PDF uploaded, interact with the AI PDF assistant to unlock its full potential. Here’s how:

1. Find the Query Field: Enter questions about the PDF’s content in the designated area.

   Clear, specific questions yield optimal results.

2. Submit Query: Send your question, and the AI analyzes it against the document’s content.
3. View AI Response: The system delivers a concise, accurate answer, powered by RAG and GPT-4 integration.

Precise queries and instant responses revolutionize learning, with AI referencing the PDF for tailored insights.

Technical Backbone: Code and Architecture

The system’s intuitive interface and AI power rely on a robust architecture, integrating Streamlit for the front-end, Langchain for the framework, and FAISS for embedding storage.

Key technologies include:

• Streamlit: Powers an accessible app front-end.
• Langchain: Provides a framework for Large Language Model applications.
• FAISS: Stores vector embeddings for efficient similarity searches.

This architecture ensures RAG’s accuracy and the interface’s intuitive design.
